Plastic kegs are an emerging option in the market, often used for one-way applications such as festivals or events where kegs are not returned. They are lightweight and less costly but generally lack the durability and reusability of metal kegs. While they can be used for certain beverages, many purists prefer metal kegs for beer due to the potential for off-flavors in plastic.
Ultimately, the choice of keg material depends on your specific needs, usage frequency, and budget. Understanding the pros and cons of each material can help you determine the best option for storing and dispensing your beverages while ensuring quality and customer satisfaction.
Keg Types by Use
Kegs are designed for various applications, with the primary types being draft beer kegs, cask ales, and soda kegs. Draft beer kegs are the most common, used for dispensing beer on tap. They come in several sizes, including half-barrel and sixth-barrel, and are compatible with various draft systems. These kegs are designed to maintain carbonation and freshness, making them ideal for bars and restaurants.
Cask ales, often referred to as real ale, are typically stored in casks rather than modern kegs. These kegs allow for natural carbonation and are often used in traditional pubs. The cask ale system emphasizes the importance of serving fresh beer, usually at cellar temperature. Home brewers often experiment with this method, appreciating the artisanal aspects of cask conditioning.
Soda kegs, or Cornelius kegs, are commonly employed for carbonated beverages, including soft drinks and cocktails. These kegs are generally smaller and made of stainless steel, designed to hold pressurized liquids.

Each keg type serves a specific purpose, and using the appropriate one guarantees an optimal experience for both the server and the consumer.
Draft Beer Systems
A draft beer system consists of several interconnected components that work together to deliver beer from kegs to taps. Key elements include the keg, coupler, lines, faucets, and a CO2 tank. The coupler is crucial as it connects the keg to the beer lines, allowing beer to flow while keeping the keg pressurized. Different couplers exist for various keg types, including D-system, S-system, and others, each designed for specific keg brands.
Beer lines transfer the beverage from the keg to the tap. Their material and diameter significantly impact the beer’s quality and temperature. Ideally, beer lines should be made of food-grade materials and kept as short as possible to minimize friction and maintain the beer’s carbonation. Regular cleaning of the lines is critical; dirty lines can lead to off-flavors and spoilage.
Faucets, typically chrome or stainless steel, dispense the beer and should be cleaned regularly to prevent contamination. The CO2 tank provides the necessary carbonation, ensuring that the beer maintains its fizz and quality. Understanding these components and how they interact is essential for optimal draft beer service and quality control.
In addition, investing in a quality draft beer system can significantly impact your beverage service. Studies indicate that establishments with well-maintained draft systems can see better customer satisfaction and increased sales.
