A new WSO2 white paper entitled "Practical SOA for the Solution Architect" positions SOA as a

... common sense discipline that is as relevant today as it has been ever since the information age began.

With this in mind, the paper tries to

... provide a practical approach to using SOA that is easily grasped and immediately applicable. It is also vendor-neutral since it deals with universally applicable concepts and also logical components that are likely to be found in any vendor’s product line-up.

The paper focuses on two most relevant aspects for a Solution Architect:

  • At the technology level, Solution Architects need to understand the right tools for the job.
  • At the data level, they need know how to reduce or eliminate unnecessary dependencies between systems.

When it comes to the technology (tools) layer, there are three core SOA technology components that are most frequently used, according to the paper:

  • The Service Container
  • The Broker
  • The Process Coordinator

These components that Solution Architects need to put together existing and planned functional components to create an end-to-end business solution should be used as follows:

  • The service container is a platform housing new services implemented as part of the solution
  • The service broker is a tool allowing to expose functionality of existing enterprise application as a service. It serves as a combined adapter/transformer/mediator for existing functionality
  • The process coordinator is used for implementing business processes, tying together execution of services.

According to the paper, in addition to these three, additional components commonly used in SOA implementations include: rules engines, data access tools, registry/repository tools, management and monitoring tools, governance tool, custom events processing, presentation support, etc.

The paper goes further, explaining that simply choosing correct technical components is not sufficient to ensure SOA success:

We need to ensure that the gains we have made through the use of appropriate SOA technology components are not negated by tightly-coupled data design.

It provides the following four rules that should be obeyed in order to achieve a SOA design with low data coupling:

  • Identify implicit data and make it explicit - hide the changes occurring inside a system to shield others by simply ensuring continuing adherence to their contracts.
  • Eliminate needless dependencies between systems - you should try and eliminate dependencies that don’t make sense.
  • Keep domain data and message data loosely coupled - rely on data mapping rather than data generation or derivation to achieve this.
  • Standardize vocabulary within a logical domain, not across the entire organization - trying to standardize vocabulary across an enterprise as a whole can be like "boiling an ocean"

The paper also provides several examples from the banking and insurance industry to explain practical applications of described concepts

It concludes by stating that:

These simple yet powerful ideas are key to effective SOA design, and you now have these conceptual tools in your repertoire of skills... [they] enable you to hit the ground running with your next project, so you can intuitively design a solution that conforms to SOA principles.

Although it is difficult to disagree with the conclusions of the white paper, and the importance of principles it defines, it does not really bring anything new compared to existing SOA publications. On the technical side, it is basically telling that the execution of services that can be either built from scratch leveraging service containers or by exposing existing legacy applications through the adapter/transformer/mediator pattern should be orchestrated by business processes. This same technical solution is a foundation of the modern ESBs. On the data side, the idea of "canonical" enterprise data model was introduced by EAI about 15 years ago and was widely adopted by many SOA implementations. As for implicit to explicit conversion and eliminating unnecessary dependencies - those are directly related to existing service design patterns - loose coupling of services and hiding service implementation behind well defined interfaces.

On another hand, reminding these principles to SOA practitioners is always useful.

Killexams : service-oriented architecture

The modularization of business functions for greater flexibility and reusability. Instead of building monolithic applications for each department, a service-oriented architecture (SOA) organizes business software in a granular fashion so that common functions can be used interchangeably by different departments internally and by external business partners as well. The more granular the components (the more pieces), the more they can be reused.

A service-oriented architecture (SOA) is a way of thinking about IT assets as service components. When functions in a large application are made into stand-alone services that can be accessed separately, they are beneficial to several parties.

Standard Interfaces

An SOA is implemented via a programming interface (API) that allows components to communicate with each other. The most popular interface is the use of XML over HTTP, known as "Web services." However, SOAs are also implemented via the .NET Framework and Java EE/RMI, as well as CORBA and DCOM, the latter two being the earliest SOA interfaces, then known as "distributed object systems." CICS, IBM's MQ series and other message passing protocols could also be considered SOA interfaces. See Web services.

Killexams : Development of a SOA Manifesto

Steve Ross-Talbot points out that there's some new work going on in defining a SOA Manifesto. Along with Steve the working group consists of people from IBM, Oracle, Red Hat and others. According to the SOA Manifesto pages, the manifesto will be ...

A formal declaration of the principles, intentions and ambitions of service-orientation and the service-oriented architectural model.

And as well as eventually being published on http://soa-manifesto.org/, there's also a meeting of the working group coming up very soon:

The "Towards an SOA Manifesto" Working Group is dedicated to producing the SOA Manifesto. The SOA Manifesto will be announced for the first time at 4:45 PM CEST on October 23, 2009 during the closing conference keynotes at the

2nd International SOA Symposium in Rotterdam, The Netherlands.

As Steve points out:

As a participant I started to look into what is out there and I must admit I am really surprised at how little there is for SOA. Of course we have patterns and principles and even governance [1, 2] for SOA but as yet no one has written a manifesto personal or otherwise to share with the industry as a whole.

He then goes on to discuss a couple of key areas where Steve thinks the working group needs to focus.

  • To ensure "that executive sponsors across industries understand what [SOA] means to them." This includes the impact of SOA on their revenue and costs (after all, successful SOA should be driven by business needs.) Furthermore the realities of SOA lifecycles (e.g., an iterative approach to getting what is actually needed, which may not be what was initially requested) should be "effectively articulated to business sponsors [to] help them make decisions."
  • As a community we need to arrive at a consensus that helps people understand what service-orientation really means, the principles behind it (business as well as architecture), and what constititutes a SOA (perhaps related to one of the SOA reference models?) Although this may seem obvious, as Steve goes on to point out "[...] in my world I often have to deal with people who equate WS-* to SOA and equate ESB to SOA. Which of course is not the case. They may help and even constrain and SOA but they not make one."

It will certainly be interesting to see what comes out of the working group efforts in the next few weeks. However, if you could provide input to it, what would that include?

Killexams : Semiconductor optical amplifier (SOA) helps high-precision measurements of atmospheric CO2 column

image: Schematic diagram of the developed SOA assisted LHS. view more 

Credit: XU Zhenyu

Recently, a research team led by associate Prof. XU Zhenyu from Hefei Institutes of Physical Science, Chinese Academy of Sciences suggested a new method to detect atmospheric greenhouse gas column with high-resolution laser heterodyne spectroscopy.

The method, which was in Optics Letter and highlighted as an Editor's Pick, solved the challenge of the increase of the collected effective radiation power limited by the restricted solid angle as described by optical antenna theory.

In the past years, Laser Heterodyne Spectrometer (LHS) was taken as a complementary tool to ground-based Fourier transform spectrometer in terms of the greenhouse gas column measurement, due to its high spectral resolution, small size and easy integration. However, for laser heterodyne spectroscopy, the signal-to-noise ratio (SNR) of heterodyne signal couldn't be enhanced by increasing the size of the optical receiver because of the optical antenna theory resulting in a limitation of the effective collected solar radiation power.

This would further limit the measurement accuracy of the greenhouse column abundances/vertical profiles.

The novel method proposed in this research improved LHS's SNR by utilizing a semiconductor optical amplifier (SOA) to resolve the issue with limited SNR induced by the optical antenna theory.

The research results showed that the precision of the greenhouse column measurement and the ability of weak light signal detection in terms of the developed SOA-assisted LHS, have achieved a great improvement compared to the traditional LHS.

This research work enhanced the performance of LHS, which showed great potential in the remote sensing of the atmospheric greenhouse gases.

"Our work improved SNR and the measurement precision of CO2 column abundance significantly. It would be promoted to mid-infrared LHR for high-resolution sensitive detection of atmospheric column or vertical profiles of more gas components," said DENG Hao, first author of this paper.

Killexams : Amazon changes e-book returns policy after discussions with SoA and Authors Guild

Amazon has agreed to change its e-book returns policy following discussions with the Society of Authors (SoA) and the US Authors Guild. 

The online giant’s returns policy for e-books currently allows readers to receive a full refund for up to 14 days, even if they have read the full work. The SoA claimed the use of this refund loophole has been encouraged by users on the social media platform TikTok, with videos on how to return books being viewed more than 17 million times.  

A petition was set up on Change.org to reduce the returns window to 48 hours, which attracted more than 78,000 signatures. High-profile authors including Jeanette Winterson and Ian Rankin also criticised the loophole and the impact this would have on authors’ profits.  

Amazon stressed at the time that its e-book return rates were “consistently low” and said it had policies and mechanisms in place to prevent this from being abused.  

The online retailer maintains there have been “no discernable spikes” in returns but confirmed a change in policy in an email on 21st September to the SoA and the Authors Guild. David Naggar, Amazon’s vice president of books and Kindle content, said: “We do hear all you have said over the course of our conversations on this syllabu and are planning to make meaningful changes... Most notably, we will de-activate self-service returns for any book read past 10%, adding substantial friction to the process.” 

He confirmed the company will introduce the change to all platforms that support Kindle, including e-readers, computers and smartphones. He said Amazon’s developers have, “reprioritized existing product roadmaps... and believe this improvement can be implemented by the end of the year”. 

A spokesperson from Amazon confirmed the statement from Naggar to The Bookseller and added: “We’re always listening to feedback to provide the best experience for customers and authors. While we continue to see low overall returns, we will de-activate the self-service return option for any book read past 10% by the end of the year.”

Commenting on the move, Nicola Solomon, SoA chief executive, said: “This is excellent news for authors, and a perfect example of what unions can achieve through lobbying together. We look forward to hearing more from David and his team at Amazon when their new system goes live. In the meantime, thank you to the many self-published authors who first brought this problem to our attention.”

Killexams : Basics Of JavaScript SEO For Ecommerce: What You Need To Know

JavaScript (JS) is extremely popular in the ecommerce world because it helps create a seamless and user-friendly experience for shoppers.

Take, for instance, loading items on category pages, or dynamically updating products on the site using JS.

While this is great news for ecommerce sites, JavaScript poses several challenges for SEO pros.

Google is consistently working on improving its search engine, and a big part of its effort is dedicated to making sure its crawlers can access JavaScript content.

But, ensuring that Google seamlessly crawls JS sites isn’t easy.

In this post, I’ll share everything you need to know about JS SEO for ecommerce and how you can Strengthen your organic performance.

Let’s begin!

How JavaScript Works For Ecommerce Sites

When building an ecommerce site, developers use HTML for content and organization, CSS for design, and JavaScript for interaction with backend servers.

JavaScript plays three prominent roles within ecommerce websites.

1. Adding Interactivity To A Web Page

The objective of adding interactivity is to allow users to see changes based on their actions, like scrolling or filling out forms.

For instance: a product image changes when the shopper hovers the mouse over it. Or hovering the mouse makes the image rotate 360 degrees, allowing the shopper to get a better view of the product.

All of this enhances user experience (UX) and helps buyers decide on their purchases.

JavaScript adds such interactivity to sites, allowing marketers to engage visitors and drive sales.

2. Connecting To Backend Servers

JavaScript allows better backend integration using Asynchronous JavaScript (AJAX) and Extensible Markup Language (XML).

It allows web applications to send and retrieve data from the server asynchronously while upholding UX.

In other words, the process doesn’t interfere with the display or behavior of the page.

Otherwise, if visitors wanted to load another page, they would have to wait for the server to respond with a new page. This is annoying and can cause shoppers to leave the site.

So, JavaScript allows dynamic, backend-supported interactions – like updating an item and seeing it updated in the cart – right away.

Similarly, it powers the ability to drag and drop elements on a web page.

3. Web Tracking And Analytics

JavaScript offers real-time tracking of page views and heatmaps that tell you how far down people are reading your content.

For instance, it can tell you where their mouse is or what they clicked (click tracking).

This is how JS powers tracking user behavior and interaction on webpages.

How Do Search Bots Process JS?

Google processes JS in three stages, namely: crawling, rendering, and indexing.

As you can see in this image, Google’s bots put the pages in the queue for crawling and rendering. During this phase, the bots scan the pages to assess new content.

When a URL is retrieved from the crawl queue by sending an HTTP request, it first accesses your robots.txt file to check if you’ve permitted Google to crawl the page.

If it’s disallowed, the bots will ignore it and not send an HTTP request.

In the second stage, rendering, the HTML, CSS, and JavaScript files are processed and transformed into a format that can be easily indexed by Google.

In the final stage, indexing, the rendered content is added to Google’s index, allowing it to appear in the SERPs.

Common JavaScript SEO Challenges With Ecommerce Sites

JavaScript crawling is a lot more complex than traditional HTML sites.

The process is quicker in the case of the latter.

Check out this quick comparison.

Traditional HTML Site Crawling JavaScript Crawling
1 Bots obtain the HTML file 1 Bots obtain the HTML file
2 They extract the links to add them to their crawl queue 2 They find no link in the source code because they are only injected after JS execution
3 They obtain the CSS files 3 Bots obtain CSS and JS files
4 They send the downloaded resources to Caffeine, Google’s indexer 4 Bots use the Google Web Rendering Service (WRS) to parse and execute JS
5 Voila! The pages are indexed 5 WRS fetches data from the database and external APIs
6 Content is indexed
7 Bots can finally discover new links and add them to the crawl queue

Thus, with JS-rich ecommerce sites, Google finds it tough to index content or discover links before the page is rendered.

In fact, in a webinar on how to migrate a website to JavaScript, Sofiia Vatulyak, a renowned JS SEO expert, shared,

“Though JavaScript offers several useful features and saves resources for the web server, not all search engines can process it. Google needs time to render and index JS pages. Thus, implementing JS while upholding SEO is challenging.”

Here are the top JS SEO challenges ecommerce marketers should be aware of.

Limited Crawl Budget

Ecommerce websites often have a massive (and growing!) volume of pages that are poorly organized.

These sites have extensive crawl budget requirements, and in the case of JS websites, the crawling process is lengthy.

Also, outdated content, such as orphan and zombie pages, can cause a huge wastage of the crawl budget.

Limited Render Budget

As mentioned earlier, to be able to see the content loaded by JS in the browser, search bots have to render it. But rendering at scale demands time and computational resources.

In other words, like a crawl budget, each website has a render budget. If that budget is spent, the bot will leave, delaying the discovery of content and consuming extra resources.

Google renders JS content in the second round of indexing.

It’s important to show your content within HTML, allowing Google to access it.

Go to the Inspect element on your page and search for some of the content. If you cannot find it there, search engines will have trouble accessing it.

Troubleshooting Issues For JavaScript Websites Is Tough

Most JS websites face crawlability and obtainability issues.

For instance, JS content limits a bot’s ability to navigate pages. This affects its indexability.

Similarly, bots cannot figure out the context of the content on a JS page, thus limiting their ability to rank the page for specific keywords.

Such issues make it tough for ecommerce marketers to determine the rendering status of their web pages.

In such a case, using an advanced crawler or log analyzer can help.

Tools like Semrush Log File Analyzer, Google Search Console Crawl Stats, and JetOctopus, among others, offer a full-suite log management solution, allowing webmasters to better understand how search bots interact with web pages.

JetOctopus, for instance, has JS rendering functionality.

Check out this GIF that shows how the tool views JS pages as a Google bot.

Similarly, Google Search Console Crawl Stats shares a useful overview of your site’s crawl performance.

The crawl stats are sorted into:

  • Kilobytes downloaded per day show the number of kilobytes bots obtain each time they visit the website.
  • Pages crawled per day shows the number of pages the bots crawl per day (low, average, or high).
  • Time spent downloading a page tells you the amount of time bots take to make an HTTP request for the crawl. Less time taken means faster crawling and indexing.

Client-Side Rendering On Default

Ecommerce sites that are built in JS frameworks like React, Angular, or Vue are, by default, set to client-side rendering (CSR).

With this setting, the bots will not be able to see what’s on the page, thus causing rendering and indexing issues.

Large And Unoptimized JS Files

JS code prevents critical website resources from loading quickly. This negatively affects UX and SEO.

Top Optimization Tactics For JavaScript Ecommerce Sites

1. Check If Your JavaScript Has SEO Issues

Here are three quick tests to run on different page templates of your site, namely the homepage, category or product listing pages, product pages, blog pages, and supplementary pages.

URL Inspection Tool

Access the Inspect URL report in your Google Search Console.

Enter the URL you want to test.

Next, press View Tested Page and move to the screenshot of the page. If you see this section blank (like in this screenshot), Google has issues rendering this page.

Repeat these steps for all of the relevant ecommerce page templates shared earlier.

Run A Google Search

Running a site search will help you determine if the URL is in Google’s index.

First, check the no-index and canonical tags. You want to ensure that your canonicals are self-referencing and there’s no index tag on the page.

Next, go to Google search and enter – Site:yourdomain.com inurl:your url


This screenshot shows that Target’s “About Us” page is indexed by Google.

If there’s some issue with your site’s JS, you’ll either not see this result or get a result that’s similar to this, but Google will not have any meta information or anything readable.

Go For Content Search

At times, Google may index pages, but the content is unreadable. This final test will help you assess if Google can read your content.

Gather a bunch of content from your page templates and enter it on Google to see the results.

Let’s take some content from Macy’s.

Macy's content

No problems here!

But check out what happens with this content on Kroger. It’s a nightmare!

Though spotting JavaScript SEO problems is more complex than this, these three tests will help you quickly assess if your ecommerce Javascript has SEO issues.

Follow these tests with a detailed JS website audit using an SEO crawler that can help identify if your website failed when executing JS, and if some code isn’t working properly.

For instance, a few SEO crawlers have a list of features that can help you understand this in detail:

  • The “JavaScript performance” report offers a list of all the errors.
  • The “browser performance events” chart shows the time of lifecycle events when loading JS pages. It helps you identify the page elements that are the slowest to load.
  • The  “load time distribution” report shows the pages that are fast or slow. If you click on these data columns, you can further analyze the slow pages in detail.

2. Implement Dynamic Rendering

How your website renders code impacts how Google will index your JS content. Hence, you need to know how JavaScript rendering occurs.

Server-Side Rendering

In this, the rendered page (rendering of pages happens on the server) is sent to the crawler or the browser (client). Crawling and indexing are similar to HTML pages.

But implementing server-side rendering (SSR) is often challenging for developers and can increase server load.

Further, the Time to First Byte (TTFB) is slow because the server renders pages on the go.

One thing developers should remember when implementing SSR is to refrain from using functions operating directly in the DOM.

Client-Side Rendering

Here, the JavaScript is rendered by the client using the DOM. This causes several computing issues when search bots attempt to crawl, render, and index content.

A viable alternative to SSR and CSR is dynamic rendering that switches between client and server-side rendered content for specific user agents.

It allows developers to deliver the site’s content to users who access it using JS code generated in the browser.

However, it presents only a static version to the bots. Google officially supports implementing dynamic rendering.

To deploy dynamic rendering, you can use tools like Prerender.io or Puppeteer.

These can help you serve a static HTML version of your Javascript website to the crawlers without any negative impact on CX.

Dynamic rendering is a great solution for ecommerce websites that usually hold lots of content that change frequently or rely on social media sharing (containing embeddable social media walls or widgets).

3. Route Your URLs Properly

JavaScript frameworks use a router to map clean URLs. Hence, it is critical to update page URLs when updating content.

For instance, JS frameworks like Angular and Vue generate URLs with a hash (#) like www.example.com/#/about-us

Such URLs are ignored by Google bots during the indexing process. So, it is not advisable to use #.

Instead, use static-looking URLs like http://www.example.com/about-us

4. Adhere To The Internal Linking Protocol

Internal links help Google efficiently crawl the site and highlight the important pages.

A poor linking structure can be harmful to SEO, especially for JS-heavy sites.

One common issue we’ve encountered is when ecommerce sites use JS for links that Google cannot crawl, such as onclick or button-type links.

Check this out:

<a href=”/important-link”onclick=”changePage(‘important-link’)”>Crawl this</a>

If you want Google bots to discover and follow your links, ensure they are plain HTML.

Google recommends interlinking pages using HTML anchor tags with href attributes and asks webmasters to avoid JS event handlers.

5. Use Pagination

Pagination is critical for JS-rich ecommerce websites with thousands of products that retailers often opt to spread across several pages for better UX.

Allowing users to scroll infinitely may be good for UX, but isn’t necessarily SEO-friendly. This is because bots don’t interact with such pages and cannot trigger events to load more content.

Eventually, Google will reach a limit (stop scrolling) and leave. So, most of your content gets ignored, resulting in a poor ranking.

Make sure you use <a href> links to allow Google to see the second page of pagination.

For instance, use this:

<a href=”https://example.com/shoes/”>

6. Lazy Load Images

Though Google supports lazy loading, it doesn’t scroll through content when visiting a page.

It resizes the page’s virtual viewport, making it longer during the crawling process. And because the  “scroll” event listener isn’t triggered, this content isn’t rendered.

Thus, if you have images below the fold, like most ecommerce websites, it’s critical to lazy load them, allowing Google to see all your content.

7. Allow Bots To Crawl JS

This may seem obvious, but on several occasions, we’ve seen ecommerce sites accidentally blocking JavaScript (.js) files from being crawled.

This will cause JS SEO issues, as the bots will not be able to render and index that code.

Check your robots.txt file to see if the JS files are open and available for crawling.

8. Audit Your JS Code

Finally, ensure you audit your JavaScript code to optimize it for the search engines.

Use tools like Google Webmaster Tools, Chrome Dev Tools, and Ahrefs and an SEO crawler like JetOctopus to run a successful JS SEO audit.

Google Search Console

This platform can help you optimize your site and monitor your organic performance. Use GSC to monitor Googlebot and WRS activity.

For JS websites, GSC allows you to see problems in rendering. It reports crawl errors and issues notifications for missing JS elements that have been blocked for crawling.

Chrome Dev Tools

These web developer tools are built into Chrome for ease of use.

The platform lets you inspect rendered HTML (or DOM) and the network activity of your web pages.

From its Network tab, you can easily identify the JS and CSS resources loaded before the DOM.

Ahrefs

Ahrefs allows you to effectively manage backlink-building, content audits, keyword research, and more. It can render web pages at scale and allows you to check for JavaScript redirects.

You can also enable JS in Site Audit crawls to unlock more insights.

The Ahrefs Toolbar supports JavaScript and shows a comparison of HTML to rendered versions of tags.

JetOctopus SEO Crawler And Log Analyzer

JetOctopus is an SEO crawler and log analyzer that allows you to effortlessly audit common ecommerce SEO issues.

Since it can view and render JS as a Google bot, ecommerce marketers can solve JavaScript SEO issues at scale.

Its JS Performance tab offers comprehensive insights into JavaScript execution – First Paint, First Contentful Paint, and page load.

It also shares the time needed to complete all JavaScript requests with the JS errors that need immediate attention.

GSC integration with JetOctopus can help you see the complete dynamics of your site performance.

Ryte UX Tool

Ryte is another tool that’s capable of crawling and checking your javascript pages. It will render the pages and check for errors, helping you troubleshoot issues and check the usability of your dynamic pages.

seoClarity

seoClarity is an enterprise platform with many features. Like the other tools, it features dynamic rendering, letting you check how the javascript on your website performs.

Summing Up

Ecommerce sites are real-world examples of dynamic content injected using JS.

Hence, ecommerce developers rave about how JS lets them create highly interactive ecommerce pages.

On the other hand, many SEO pros dread JS because they’ve experienced declining organic traffic after their site started relying on client-side rendering.

Though both are right, the fact is that JS-reliant websites too can perform well in the SERP.

Follow the tips shared in this guide to get one step closer to leveraging JavaScript in the most effective way possible while upholding your site’s ranking in the SERP.

Killexams : Amarone — A Guide to the Basics

Amarone has a well-earned reputation for power. After all, it's not uncommon to find bottles that clear 15.5% ABV and approach 16% or more. But the best examples are about much more than sheer strength: They are layered, deeply complex reds that are inextricably tied to the land in which their constituent grapes are grown. Because of the unusual technique employed in their production, these wines have the ability to showcase an entirely different aspect of both the varieties in the blend and the terroir in which their roots are sunk.

What is Amarone Wine?

Amarone is a rich, expressive red wine from the Veneto region of northeastern Italy. Its full name is Amarone della Valpolicella, and it's produced from a blend of grapes including Corvina, Corvinone, Rondinella, and (less commonly these days) Molinara. These are the same grapes that go into Valpolicella, the more traditionally produced red wine (harvest grapes, crush them, macerate the juice and skins, ferment the juice, etc.). However, for Amarone, those grapes are dried following harvest, and it's the raisinated fruit that gets pressed and fermented. This drying of the grapes concentrates the sugars and completely changes the balance of juice and skin. The combination of both means that there is more sugar for the yeast to ferment into alcohol, leading to more powerful wines. There is also more tannin, since the skins play a more significant role. Amarone, in fact, loosely translates to "big bitter."

Where Does Amarone Wine Come From?

Amarone comes from Valpolicella, which is in the Veneto region of northeastern Italy. There are four main types of wine that are produced there: Valpolicella, which is made like most other red wines; Valpolicella Ripasso, for which red wine is then refermented with the dried skins of grapes that were crushed for Amarone, which lends Ripasso greater power and complexity than ordinary Valpolicella yet less assertive power than Amarone itself; Amarone; and Recioto della Valpolicella, a sweet wine from the region. Within the category of Amarone della Valpolicella, there are several distinctions, including Amarone della Valpolicella Classico (sometimes called Amarone Classico della Valpolicella) and Amarone della Valpolicella Superiore.

All Amarone wines are produced using the grape-drying technique, which is called appassimento in Italian. For an excellent expression of Valpolicella that's not Amarone, check out Le Ragose Valpolicella Classico Superiore Ripasso, whose bright red cherry and black raspberry notes are anchored by leather, tobacco, cocoa powder, and dark woodsy spices.

Why Should You Drink Amarone Wine?

Amarone is a thoroughly unique wine not just in Italy, but in the entire world. Of course, there are other wines that are produced using the grape-drying or appassimento method, but Amarone brings together the unique characteristics of its various Valpolicella terroirs and the character of its main constituent grape varieties to result in a wine that is unlike any other. At its best, Amarone is just as nuanced as it is powerful.

Amarone is also a remarkably age-worthy wine. Not all examples are meant to be laid down in a cellar for decades, and shifting consumer preferences mean that there are plenty of bottles that can absolutely be enjoyed in the short term, but Amarone is still a category with a preponderance of producers whose best wines can continue improving for decades. Still, the world of Amarone has changed: A generation ago, many of them were difficult to enjoy in their youth, with overwhelming tannic structures that more or less required several years' of age before they became pleasurable. But that has changed today, and consumers can enjoy many Amarones at various stages throughout their evolution in the bottle, and even in their youth.

For fans of richer foods, Amarone is a fantastic option. With braised meats like oxtails and short ribs, Amarone is a great pairing partner. Smoked meats and barbecue across the range of regional styles often find a phenomenal partner in Amarone: It can frame spice rubs brilliantly, and won't likely be overwhelmed by sweeter or more tangy sauces. It also is a great choice for creamy and hard cheeses, as well as dessert, especially chocolate-based ones and even cheesecake. Amarone also tends to work well with fruit-based desserts, assuming they aren't too sweet.

Because of its higher alcohol content, Amarone is best enjoyed at slightly less than room temperature, but too much of a chill will make the tannins come to the fore in too assertive a manner and seem bitter. To that end, a large glass, like a Cabernet Sauvignon or big-bowled universal glass, is a good choice, the better to facilitate vigorous swirling, which will help soften up those tannins and allow the underlying characteristics to shine through.

What Does Amarone Taste Like?

Amarone is a rich wine with a prominent tannic structure. It often smells as if it will be sweet, with ripe black and red cherries, blackberries, dried figs, raisins, coffee notes, and chocolate, but the first sip tends to prove the opposite: For all of the ripe, generous fruit, Amarone is a dry wine, and the sweet assumptions from the nose often result in a riveting sense of tension when the first sip proves the opposite to be true. Amarone can also be aged for an extended period of time in barrels, and depending on the nature of the wood that they're composed of, and how old they are, sweet spices like vanilla and cinnamon may also be present, as well as chocolate, cocoa powder, and coffee.

There are countless great Amarone wines on the market today. These five producers, listed alphabetically, are a perfect way to start exploring all that Amarone has to offer.

Bertani

One of the more well-known names in the world of Amarone, Bertani produces Amarone, Valpolicella Ripasso, Recioto della Valpolicella, and more. Their 2011 Amarone della Valpolicella Classico is remarkable: Powerful yet elegant, savory yet still with a maturing core of fruit, and boasting a long, harmonious finish. The palate here runs the gamut from dried figs and brambly berries to leather, olive pit, maduro cigar tobacco, and star anise, all of it haunted in the background by dried flowers.

Dal Forno Romano

Dal Forno is one of the legends of Amarone, an icon, and a producer of wines that have earned their place on top wine lists around the world. In vintages that aren't up to their exacting levels of excellence they just don't make an Amarone, and in the past 20 years they've chosen to skip 2005, 2007, and 2014. Their 2015 Amarone della Valpolicella Monte Lodoletta dramatically proves why this strategy is worth missing the occasional release: It's an unforgettable wine, complex and impossibly long, concentrated and impeccably balanced, and scented with tar, crushed flowers, and blackberry liqueur that pave the way for a palate that drips with blackberry liqueur, black cherries, candied violets, very high-cacao dark chocolate, espresso beans, Chinese five-spice powder, and dried figs. The finish shimmers with black licorice and leather and lingers for a full minute. Now or in two decades (or more, easily), this is a wine of astounding accomplishment.

Famiglia Pasqua

With roots stretching back nearly a century (it was founded in 1925), Pasqua is a thoroughly forward-thinking company, with a focus on not just the liquid inside the bottle but the aesthetics of the packaging itself. Their 2017 Amarone della Valpolicella is a silky, polished expression of Amarone, with kirsch-filled dark-chocolate ganache, cinnamon-dusted espresso, and dried black figs.

Masi

Masi produces one of the most familiar Amarone bottlings on the American market, the Costasera, but they also make the brooding-yet-expressive Vaio Armaron Amarone della Valpolicella Classico. It's grown on the Serego Alighieri estate, which was purchased in 1353 by Piero Alighieri, the son of Dante. The 2013 is outstanding, a dark-fruited wine that unfolds in layers of dried black figs, dark chocolate ganache, blackberries, licorice, and cafe mocha, all of it gently spiced with cinnamon and star anise.

Podere Poiana

The 2016 Amarone della Valpolicella is dense, deep, and rich, dramatic with raisins, sweet spices, melted chocolate ganache, rooibos, and Earl Grey tea flavors rolling through the long, dried-flower-flecked finish.
