What is Draft Beer? Understanding the Basics
Draft beer, also known as draught beer, is beer served from a keg or cask rather than a bottle or can. Unlike packaged beer, draft beer is typically fresher and has a fuller flavor due to minimal exposure to light and oxygen.
This type of beer is stored in kegs and served through pressurized taps, which helps maintain its carbonation and taste.
Draft beer comes in various types, including keg beer, which is carbonated with CO₂, and cask ale, which is naturally carbonated and unfiltered, offering a smoother mouthfeel.
Many people prefer draft beer for its fresh taste and unique pouring experience.
Draft vs. Draught Beer: What’s the Difference?
When ordering beer, you might see it labelled as either “draft” or “draught.” While these terms are often used interchangeably, they have subtle differences that vary by region and serving style. Let’s break down the main distinctions.
1. Terminology and Regional Preference
- Draft Beer: The term “draft” is primarily used in the United States to refer to beer served from a keg, tap, or cask. It’s a general term encompassing any beer served fresh from a pressurized system, typically found in bars and pubs.
- Draught Beer: Used more commonly in the United Kingdom and Commonwealth countries, “draught” historically referred to cask-conditioned ales served using a hand-pump system. Today, it also includes kegged beer but is associated with a more traditional beer-serving style.
2. Serving Method
- Draft Beer: Served through pressurized taps, usually with added CO₂, which keeps the beer fresh and provides a crisp, carbonated mouthfeel.
- Draught Beer: Frequently served through a hand pump or gravity system, especially for traditional ales in the U.K. This method results in softer carbonation and a smoother, more authentic flavour, especially for cask ales.
3. Carbonation and Flavor
- Draft Beer: Known for its crisp and refreshing quality, draft beer typically has added CO₂, offering a stable and consistent flavour profile.
- Draught Beer: If cask-conditioned, draught beer has natural carbonation from secondary fermentation, giving it a gentle effervescence and allowing for more complex flavours to develop.
Final Thoughts
While both draft and draught beer are served fresh from a keg or cask, draft generally refers to American-style, pressurized beer, while draught emphasizes a traditional, authentic serving method popular in the U.K. and Commonwealth countries.
Whether you prefer the crispness of the draft or the nuanced flavours of draught, knowing these distinctions can enhance your appreciation of each pour.
Key Differences Between Draft and Bottled Beer
When it comes to enjoying beer, the choice between draft and bottled beer can significantly affect the flavour, freshness, and overall experience. Here are the key differences:
Storage and Dispensing:
- Draft Beer: Stored in kegs and dispensed through taps, draft beer typically maintains freshness and carbonation levels better than bottled beer. The pressurized environment of a keg helps preserve the beer’s intended flavour profile until served.
- Bottled Beer: Packaged in bottles, which can be susceptible to light and oxygen exposure, bottled beer often has a shorter shelf life. The cap can introduce oxygen when opened, potentially affecting the taste over time.
Freshness:
- Draft Beer: Generally considered fresher, draft beer is often served directly from the keg to the glass, minimizing exposure to air and light, which can degrade flavour. Many craft breweries even serve their beers on draft within days of brewing.
- Bottled Beer: While many bottled beers are also crafted with care, the time between brewing, bottling, and consumption can lead to less freshness compared to draft beer. Some styles of beer, like IPAs, are best consumed fresh, making draft a more appealing option.
Flavor Profile:
- Draft Beer: The serving process can enhance the beer’s aroma and flavor. The larger serving size and proper pouring techniques in bars can contribute to a better-tasting experience.
- Bottled Beer: Flavor can vary due to bottle conditioning or pasteurization, which may alter the beer’s original taste. However, many bottled beers, especially craft options, are brewed with an emphasis on unique flavours and ingredients.
Carbonation Levels:
- Draft Beer: Typically has a smoother and creamier mouthfeel due to the nitrogen or CO2 dispensing methods used in bars. The controlled environment allows for consistent carbonation levels.
- Bottled Beer: Carbonation can vary depending on the bottling process and whether the beer is bottle-conditioned. This can lead to a different mouthfeel and experience when drinking.
Availability and Variety:
- Draft Beer: Often showcases local breweries and limited-edition releases that may not be available in bottles. Bars frequently rotate their draft selections to offer customers new experiences.
- Bottled Beer: Widely available and can be purchased for home consumption, offering a broader selection of styles and brands, including those that may not be on draft.

How Draft Beer is Made and Stored
Production Process of Draft Beer
The production of draft beer follows the same basic brewing principles as bottled beer but is tailored for optimal freshness. The brewing process involves:
- Mashing: Combining malted grains with water to extract sugars.
- Boiling: Adding hops to impart bitterness and aroma.
- Fermentation: Yeast converts sugars into alcohol and carbon dioxide.
- Conditioning: Beer is allowed to mature, which develops its flavour.
This production method emphasizes quality, and many breweries produce draft beer specifically for tap systems, ensuring it retains its freshness from brewery to glass. If you want to learn the beer-making process check out our guide on: How Beer is Made: A Detailed Step-by-Step Guide
Keg and Cask Storage
Key Differences Between Keg and Cask Storage
Let’s break down the main differences to see how each storage method affects the beer experience:
Carbonation
- Keg: Uses external CO₂ to maintain a consistent level of carbonation, resulting in a crisp, refreshing mouthfeel.
- Cask: Carbonation is naturally produced through fermentation in the cask, giving the beer a softer, more subtle effervescence.
Temperature Requirements
- Keg: Stored at colder temperatures (36–38°F) to retain freshness and consistency. This setup is typical for beers that benefit from a crisp, cold serve.
- Cask: Stored at cellar temperatures (50–55°F) to enhance natural conditioning. These warmer temperatures allow the beer’s flavours to develop and mellow, making them more pronounced upon serving.
Serving Temperature
- Keg: Typically served at 38–42°F, giving it a refreshing, chilled quality that’s popular in warmer environments and with highly carbonated beer styles.
- Cask: Served around 50–55°F, providing a more balanced, nuanced flavour experience, especially suited for traditional ale styles.
Handling and Dispensing
- Keg: Requires a pressurized tap system with CO₂ for dispensing, which maintains carbonation throughout the serving process.
- Cask: Dispensed by gravity or through a hand-pump system (beer engine), preserving the natural carbonation without adding external gases.
Shelf Life
- Keg: Due to refrigeration and pressurization, kegs have a longer shelf life, sometimes lasting weeks or even months if unopened.
- Cask: With a shorter shelf life (around 3–7 days once tapped), cask beer is best consumed fresh to capture its authentic flavour profile.
Flavor Profile
- Keg: Offers consistent, stable flavours that are preserved over time. CO₂ pressurization keeps the taste reliable and well-carbonated.
- Cask: Known for its dynamic flavour profile that evolves with time. Natural conditioning gives it a unique, evolving character that adds depth and complexity to each pint.

The Unique Qualities of Draft Beer
Freshness and Flavor Profile
Draft beer is celebrated for its freshness, which significantly impacts its flavour profile. The reduced exposure to light and oxygen helps retain the beer’s intended taste, allowing the unique characteristics of the ingredients to shine through.
For instance, hoppy IPAs can showcase their aromatic profiles, while malty stouts can deliver rich, chocolatey notes.
Draft Beer Alcohol Content
The alcohol content of draft beer varies based on the style, typically ranging from 4% to 8% ABV (alcohol by volume). However, some craft beers can exceed this range, reaching up to 12% or more.
Understanding alcohol content is important for responsible consumption and can enhance the overall drinking experience.
The flavor of draft beer can be distinctively richer than that of bottled beer, due to its unpasteurized and minimally processed nature.
The American Society of Brewing Chemists notes that draft beer’s natural carbonation helps accentuate flavours, making it especially appealing for beer connoisseurs.
Dispensing Draft Beer: The Equipment & Techniques
Kegs, Taps, and Beer Lines
The quality of draft beer is heavily influenced by its dispensing equipment. Key components include:
- Kegs: These store the beer and maintain its freshness.
- Taps: The system used to pour beer from kegs; they should be cleaned regularly to prevent off-flavors.
- Beer Lines: The hoses that connect kegs to taps; must also be kept clean to avoid contamination.
Regular maintenance of this equipment is essential for ensuring that every pour is as fresh as possible.
Types of Draft Beer Dispensers
Draft beer is dispensed using either CO2 or a nitrogen mix.
- CO2 Systems: Provide a crisp, carbonated experience and are most common for beers that benefit from higher carbonation levels.
- Nitrogen Systems: Create a smoother, creamier mouthfeel, which is ideal for stouts and porters . Understanding the differences in dispensing can help consumers choose the right beer for their preferences.
Tap Cleaning and Maintenance
To maintain the quality of draft beer, regular cleaning of the tap system is vital. Tap lines should be cleaned every two weeks to prevent the build-up of bacteria and residue, which can lead to off-flavours.
Ensuring a clean tap system not only enhances flavor but also promotes better customer experiences.
Types of Draft Beer: Keg, Cask, and More
Draft beer is widely appreciated for its fresh, vibrant flavours, but did you know there are various types of draft beer, each served from different systems and offering unique characteristics?
From traditional cask ales to the pressurized kegs commonly used in bars, each draft beer type offers a unique experience.
Here’s a closer look at the main types of draft beer and what makes each one distinct.
1. Keg Beer
Keg beer is one of the most popular types of draft beer, widely served in bars, restaurants, and pubs. Stored in a pressurized container, it’s typically kept at a controlled temperature and served using CO₂ or mixed gas, maintaining freshness and carbonation.
This system allows for a consistent, crisp pour every time, making it ideal for a wide range of beer styles.
- Common Styles: Lagers, IPAs, stouts, and more
- Flavor Profile: Clean, with balanced carbonation and consistent freshness
- Serving Method: Dispensed through a tap system using CO₂ or nitrogen for a controlled pour
2. Cask Ale
Cask ale, also known as “real ale,” is a traditional British beer style that’s naturally carbonated and conditioned in the cask itself, without additional CO₂. Served through a hand pump or by gravity (without added gas), cask ale is unpasteurized and often served at cellar temperature, offering a smoother mouthfeel and complex flavors.
- Common Styles: English ales, bitters, porters
- Flavour Profile: Naturally carbonated, with a softer texture and nuanced flavors that develop over time
- Serving Method: Poured through a hand pump or by gravity, without added gas, offering a more traditional, authentic experience
3. Nitro Beer
Nitro beers are pressurized with nitrogen instead of CO₂, giving the beer a creamy, smooth mouthfeel and a cascading effect in the glass. Nitrogen’s smaller bubbles make for a softer carbonation, ideal for richer beer styles that benefit from a velvety texture.
Nitro taps are commonly used for stouts and porters but have expanded to other styles for a unique draft experience.
- Common Styles: Stouts (e.g., Guinness), porters, cream ales
- Flavor Profile: Smooth, creamy, with a thick head and a rich texture
- Serving Method: Dispensed with a nitrogen tap system for a cascading pour and creamy finish
4. KeyKeg
The KeyKeg is a newer draft beer system that utilizes a lightweight, recyclable keg with an inner bag. Beer is stored in this bag, and when gas pressure is applied, the bag pushes the beer out without direct contact with the gas, preserving its natural flavor profile.
KeyKegs are popular for their convenience and sustainability, as they’re easy to transport and fully recyclable.
- Common Styles: Wide variety, especially popular with craft breweries
- Flavor Profile: Retains freshness, with no CO₂ contact, preserving the beer’s original taste
- Serving Method: Uses an inner bag system where gas pressure pushes the beer out, reducing oxygen exposure
