When purchasing a keg (also called a "keg"), there are a few important aspects to consider to ensure you choose the right one for your needs and use it safely and efficiently. Whether for personal use, a party, or a catering business, here are the key points to consider when purchasing a keg:
1. KEG size and capacity
Kegs come in a variety of sizes, from small kegs of around 5 liters for home use to large kegs of 30 liters or more for catering. Consider in advance how much beer or beverage you need and how much space you have for storage and refrigeration. For larger parties, a 20- to 30-liter keg is usually suitable, while smaller parties are often well served with a 5-liter keg.
2. Material and durability
Most kegs are made of stainless steel, which gives them a long service life and high durability. Stainless steel is particularly hygienic and robust, providing optimal protection for the contents. Plastic kegs are lighter and often cheaper, but less durable and more prone to damage. For long-term use, stainless steel kegs are therefore the better choice.
3. Connection systems and compatibility
There are various connection systems you should consider to ensure your keg is compatible with your dispensing system. In Germany, the most common systems are the "flat" fitting, "basket fitting," and "basket" adapter. Check which system you need and whether your dispensing system is compatible with it. A keg with the wrong connection will not be usable without an adapter.
4. CO₂ supply and pressure control
Kegs typically require a CO₂ supply to pressurize the beverage and expel it from the keg. Make sure you have a suitable CO₂ cylinder and a pressure regulator on hand. The pressure should typically be between 1.5 and 3 bar, depending on the type of beverage and the ambient temperature.
5. Cooling
Beer and other beverages in kegs should be stored cool, ideally between 4 and 8°C. If you don't have a professional refrigeration system, mobile coolers, buckets of ice, or refrigerators for smaller kegs can be used. Please note that beer deteriorates more quickly at higher temperatures and the flavor may be affected.
6. Deposit system and return
Many kegs are sold under the deposit system, which means you pay a deposit upon purchase, which you get refunded upon returning the empty keg. Find out about the terms and conditions in advance and make sure you can return the keg in time after use to get the deposit back.
7. Cleaning and care
Especially if you're purchasing a keg for repeated use, cleaning is crucial. Stainless steel kegs are easy to clean and often dishwasher safe. Ensure the keg is thoroughly cleaned after each use to maintain hygienic conditions and prevent flavor changes in the beverage.
8. Security aspects
Kegs are pressurized, and improper handling can be dangerous. Ensure correct pressure setting and proper CO₂ handling. Never strike a keg directly, and ensure all closures and fittings are securely fastened to prevent leaks or pressure loss.
With these tips, you can choose a KEG that perfectly suits your application and, when handled properly, delivers the best results.
