Kegs are a popular choice for storing and serving beer in bars, restaurants, breweries, and at home. A keg is a cylindrical container that can hold a large volume of beer and keep it fresh for an extended period. Kegs can be made of stainless steel and consist of several parts that work together to maintain the quality of the beer.
The main body of a keg is called the barrel, which is made of stainless steel and has a double wall that helps keep the beer cold. The lid of the keg sits on top of the barrel and is secured by a latch or key. It seals the keg and prevents any product from escaping. The internal fittings of the keg include the spear, gas hose, which is a tube that extends into the keg and allows the beer to be dispensed, and the valve, which controls the flow of beer out of the keg.
Understanding the different parts of a keg is essential for anyone who wants to store and serve beer properly. By knowing how the barrel, lid, internal fittings, coupler, and beer taps work together, you can ensure that your beer stays fresh and maintains its quality. Whether you're a bartender, homebrewer, or just a beer enthusiast, learning about all the parts of a keg is a crucial step in enjoying great-tasting beer.
Understanding Kegs
Types of Kegs
Kegs come in different types and sizes, and each one is designed for a specific purpose. The most common types of kegs are the half-barrel keg, which holds 15.5 gallons of beer, and the pony keg, or quarter barrel, which holds 7.75 gallons of beer. There are also smaller kegs, such as the corny keg, or sixth barrel which holds 5 gallons of beer. Full kegs, on the other hand, can hold up to 30 gallons of beer.
Materials and Construction
Kegs are typically made of stainless steel, which is durable, corrosion-resistant, and easy to clean. The keg shell is the most important part of the keg, and it is usually made of two layers of stainless steel. The inner layer is polished to a mirror finish to prevent contamination, while the outer layer is insulated to keep the beer cold. The keg also has a lid, which is sealed with a gasket to prevent leaks. The lid has a pressure relief valve, which allows excess pressure and air to escape.
Beer Keg
Components of a Keg
A typical keg consists of several components and accessories, each playing a crucial role in the dispensing process.
Tap and Faucet
The tap and faucet are the most visible components of a keg. They are used to dispense beer from the keg. The tap or beer coupler is attached to the keg valve, while the faucet lever is attached to the tap handle. The valve holds the beer inside the keg while the faucet lever and tap allows it to flow. Keg taps come in different types, including Sankey couplers and keg couplers. The faucet lever is typically made of brass or stainless steel and has a lever that controls the flow of beer.
Beer Lines and Seals
The beer lines and seals are used to transport beer from the keg to the draft beer faucet. The draft beer faucet line is a tube that connects the draft beer faucet back to the keg. The line is typically made of food-grade plastic or vinyl. The seals are used to prevent leaks and maintain the pressure inside the keg. They are typically made of rubber or silicone and are placed between the various components of the keg.
Spear and Dip Tube
The spear and dip tube are used to pull and dispense beer from the keg. The spear is a metal tube that is inserted into the keg and is used to pull and inject gas into the keg. The dip tube is a metal tube that extends from the spear to the bottom of the keg. It is used to draw beer from the keg and transport it to the beer line.
In summary, a keg consists of several components, including the tap and beer faucet itself, beer lines and seals, spear, and dip tube. Each component plays a crucial role in the whole draft system and beer dispensing process, and it is essential to ensure that they are all in good working condition to avoid any issues during dispensing.
Kegging Equipment
Kegging equipment is essential for the storage, dispensing, and delivery of draft beer. From kegerators to CO2 tanks and regulators, there are many components that go into a good kegging setup for draft system. In this section, we will explore the different types of kegging equipment and how they work in draft beer system.
Kegerators and Draft Beer Systems
A kegerator is a refrigerator that is specifically designed to hold a keg of beer and dispense it through a two tap system. It is an excellent choice for homebrewers who want to enjoy draft beer without the hassle of filling bottles. A kegerator typically comes with a drip tray, CO2 tank, regulator, and beer lines. It is important to choose a kegerator that is the right size for your keg and has the necessary features for your draft beer dispensing needs.
CO2 Tanks and Regulators
CO2 tanks, accessories and regulators are essential accessories for carbonating and dispensing beer from a keg. The CO2 tank is filled with compressed gas, which is used to push it out of the keg. The regulator controls the flow and pressure of the gas, which affects the carbonation and dispensing of the beer. It is important to choose a regulator that is compatible with your CO2 tank and has the necessary features for your needs.
Hand Pumps and Dispensers
Hand pumps and dispensers are an alternative to CO2 tanks and regulators. They use air pressure to dispense beer from a keg, making them ideal for outdoor events or situations where electricity is not available. Hand pumps require manual pumping to dispense the beer, which can be tiring and affect the quality of the beer. Dispensers are a more convenient option that uses a pressurized air tank to dispense the beer.
Beer in Kegs
When it comes to serving beer, kegs are a popular choice among beer bar enthusiasts. They are durable, portable, and can hold a large amount of beer. In this section, we will discuss the different types of beer and beverages that can be sold separately stored in kegs, the importance of beer taps and lines in beer bar, and how flavors and quality can be affected.
Types of Beer
Kegs can hold a variety of beers, including craft brew beer, other beers, and imported beer. Draft beer is a type of beer that is not pasteurized, and it is typically served cold. It's a beer that is brewed by small, independent breweries, and it often has unique flavors and ingredients. Imported beer is a beer that is brewed in a different country and then imported to the United States.
Beer Taps and Lines
Beer taps and lines are important parts of a keg system. The tap is the device that dispenses the beer, and the lines are the tubes that transport the beer from the keg to the tap. It is important to keep the lines clean to prevent bacteria from growing, which can affect the taste of the beer.
Flavors and Quality
The flavor and quality of beer can be affected by several factors when stored in a keg. Carbonation is important for the taste of the beer, and it can be affected by the pressure inside the keg. Oxygen can also affect the taste of the beer, as exposure to oxygen can cause the beer to become stale.
When storing beer in a keg, it is important to consider the type of beer, the cleanliness of the system, the lines and tap, and the factors that can affect the flavor and quality of the beer in given keg.

Maintaining Your Keg
Preventing Leaks and Maintaining Pressure
To ensure the longevity of your keg, it is crucial to prevent leaks and maintain pressure. The first step in preventing leaks is to check for an airtight seal between the keg and the keg coupler. This seal must be tight to prevent any leaks. If there is a leak, it could be due to a faulty washer or keg coupler. It is essential to replace any damaged washers or keg couplers immediately to prevent beer wastage.
Maintaining pressure is critical to the flow of beer from the keg. To maintain pressure, check the carbon dioxide (CO2) tank regularly. If the pressure is too low, the beer will not flow through d system correctly, and if it is too high, it can cause the beer to foam excessively. It is recommended to keep the pressure between 12-14 psi for most kegs.
Cleaning and Care
Keeping your keg clean is essential to prevent any build-up of bacteria or unwanted flavors. Regularly cleaning and sanitizing your keg, along with its components, will ensure that your beer tastes fresh and delicious. It is recommended to clean your keg after every use.
Troubleshooting
If you encounter any issues with your keg, such as a slow flow of beer or excessive foam, there are a few things you can check. First, ensure that the keg is properly pressurized and that the CO2 tank is not empty. If the pressure is correct, check the beer faucet, handle, and the keg coupler list for any damage or blockages. Check the spears sometimes these can become loose with keg couplers and if they do ask your distributor for another keg.
