In European countries where the metric system is used, kegs come in 25 and 50 liters as a standard. It is common to refer to the size not in liters but in beers. The standard beer size is .5 liters so a 50-liter keg would be 100 beers. However, beer kegs can come in many sizes:
The 1/4 keg, also known as the pony keg, contains 7.75 gallons and serves 82 12-ounce or 62 16-ounce beer. The 1/6 keg contains 5.16 gallons and serves 56 12-ounce or 42 16-ounce beers. Using this information, the size and number of kegs needed to serve a specific number of people can be estimated.
