Classification of Craft Beer

When it comes to beer, it is well known fact that there are more than enough varieties to go around.

Whether it is the flavor, ageing or anything else, beer comes n a variety of different styles, each of them having something very distinct and separate from the rest.

This is true whether you are talking about regular or craft beer.

For those who would like to know about craft beers, they are the beers made by what are called craft breweries.

The craft breweries in turn, are those breweries that can be described as small breweries, typically run by a family or sometimes a small company.

Simply put, they are the exact opposite of most mainstream beer companies, which are large companies operating across multiple markets and offer a range of different alcohol varieties.

They are generally more expensive than the mainstream varieties of beer, given that they are produced in small batches, and often have the brand image of being distinct and special.

Craft beers are today one of the most popular varieties of beer around. Popular for their unique taste, flavor and more, craft beers are preferred by many over mainstream beers.

Coming to craft beer, it becomes clear on closer examination that there is indeed a great variety of it almost everywhere.

There are in fact several different varieties of craft beer around. Each of them have their own unique characteristics, and are often specific to locations as well.

At the same time however, there are two major variants of craft beers according to most people. They are ales and lagers.

1.) Ales

Ales are the most commonly found craft beer varieties around. In addition to this, they are also the older of the two varieties, with a history that goes back thousands of years.

Ale is a generic term, and has several different varieties under it. Ales are prepared using a style of brewing, where the fermentation is done at a fairly rapid rate, with the help of top-fermenting yeast and the process is carried out in a warm environment. The process of preparing ales can be done in about one or two weeks.

An important thing to note about ales is that they are generally cheaper than lagers. Given their short preparation time, the cost of producing ales is very less in comparison to lagers. It is one of the main reasons why ales are consumed more widely than lagers.

Ales can be served at a variety of different temperatures, whether it be chilled or at room temperature.

There are several different varieties of ales. They are as given in the list below:

• Pale Ale –The pale ales are light colored and have a sharp and very bitter flavor.
• Brown Ale –The brown ales can come in a variety of different colors, ranging from reddish to brownish. Brown ales have a fairly mild flavor in comparison to other ales.
• Porters –porters are a dark variety of ales and come with a flavor described as being similar to chocolate, coffee or roasted grains.
• Stouts  –Another variety of ales are stouts. Stouts are a dark variety of beer, which come in a rich flavor like no other. They are described as being thick in comparison to other beers, with the flavor itself being similar to that of coffee, chocolate or molasses.

2. Lagers

Another variety of craft beer that is widely consumed is lagers.

Lagers are not as common or popular as ales, although they can be found in just about all craft breweries.

The lagers are made using bottom-fermenting yeast, with the fermentation process done at fairly colder temperatures.

The process of preparing lagers is generally long and can last several weeks or even months, due to the cold conditions that it is prepared in. Also to note is that it is generally more expensive than ales, given the longer period of time it takes for the preparation process to complete. It is for this reason that lagers are generally preferred less, in comparison to that of ales.

The cold fermentation process is great for the finished product, as the beer is described as having a clean, smooth and crisp taste. In general, many brewers believe that this is one of the best ways to prepare beer, as it helps the fermentation process to take place in a steady and smooth manner.

Also to add here is that while other beers are served at room temperatures, it is not the case for lagers; the serving of lagers is always done at a cold temperature.

Some of the different varieties of lagers are as given in the list below:

• Pale Lagers –Pale lagers are easy to recognize, due to their distinct color and body. The lagers have a very light and refreshing taste, and come highly carbonated.
• Marzens –Also called Oktoberfest beer, they come in a dark copper or amber color, and have a toasty rich flavor. Also to add here is that marzens tend to be maltier in comparison to other lager varieties.
• Pilsners –These are some of the lightest lagers around, and have a fairly bitter and distinct flavor. In addition to this, they are also highly carbonated.
• Bocks –Bocks are a very unique kind of lager, known for their distinct taste. The taste of bocks is described to be a mix of sweet and bitter, and can come in a variety of different colors. In addition to this, bocks also come with a largely malty flavor in comparison to other beer varieties around.

Do note that there are indeed other styles of beer as well, which have not been covered here. This is especially the case when it comes to the different kinds of ales and lagers.

In all, craft beer comes in a variety of different styles, each of them unique in their own way, whether it is flavor, taste, alcohol concentrations or anything else.

This makes craft beer one of the most interesting of all, when it comes to exploring the variety of beer that currently exists out there.

Additional FAQs about Craft Beer

• Q: How do ales and lagers differ at the yeast level?
  A: Ales use top-fermenting Saccharomyces cerevisiae at warmer temps (typically 18–22°C), producing more esters/phenolics; lagers use bottom-fermenting S. pastorianus at cooler temps (8–13°C), yielding cleaner profiles.
• Q: What ABV ranges are common across craft beer styles?
  A: Session beers: 3–4.5% ABV; most pale ales/IPAs: 5–7.5%; imperial stouts/barleywines: 8–12%+. Always check the label—style guidelines vary.
• Q: Are “cold IPA,” “India pale lager (IPL),” and “Italian pilsner” ales or lagers?
  A: Cold IPA is usually brewed with lager yeast at cooler temps but hopped like an IPA; IPL uses lager yeast and lagering; Italian pilsner is a dry-hopped pale lager. They blur the ale/lager divide via hopping and fermentation choices.
• Q: What’s the role of adjuncts (wheat, oats, rice, corn) in craft beer?
  A: Adjuncts adjust body, mouthfeel, head retention, and flavor. Oats/wheat add softness and haze (e.g., NEIPA); rice/corn can lighten body and dryness (common in some lagers).
• Q: How should craft beer be stored and served for best flavor?
  A: Keep cold (ideally 1–4°C), minimize light/oxygen exposure, and serve style-appropriate: most lagers 3–5°C; pale ales 5–7°C; stouts 10–13°C. Freshness is critical for hop-forward styles.

2025 Industry Trends in Craft Beer Classification

• Style convergence: hybrid styles (e.g., cold IPA, thiolized pale ales) gain menu share, while classic pilsners and bitters see a quality-led revival.
• Yeast innovation: thiol-releasing and kveik strains widely adopted to enhance tropical aromatics and faster turnarounds.
• Lower-ABV and gluten-reduced craft options expand as wellness-driven segments grow.
• Data-driven sensory: breweries formalize lexicons and use digital panels to tighten style consistency.
• Premiumization continues for barrel-aged and mixed-fermentation programs despite overall flat volumes.

Latest Research Cases

Case Study 1: Standardizing Hazy IPA Sensory to Reduce Batch Variance (2025)

• Background: A mid-size craft brewery had inconsistent aroma intensity across Hazy IPA lots despite fixed recipes.
• Solution: Implemented dissolved oxygen limits at dry hop (<50 ppb), thiolized yeast for enhanced tropical notes, and a digital sensory panel with trained descriptors.
• Results: Batch-to-batch aroma variance (panel score SD) dropped 31%; consumer repurchase rate improved 12% in 90 days.

Case Study 2: Repositioning Craft Lagers for Growth (2024/2025)

• Background: A regional brewer sought to diversify beyond IPA and align with rising lager interest.
• Solution: Launched an Italian pilsner and a cold-fermented “craft light” lager; optimized lagering to 21–24 days; adopted foam-positive processes and tight DO control on packaging.
• Results: Lager mix grew from 7% to 16% of sales in 10 months; returns for staling off-flavors decreased 22% per 10,000 cases.
