How Long Will a Keg of Beer Stay Fresh Once it is Tapped?
Draft beer, especially non-pasteurized, should be kept cold, preferably at about 38°F and consumed within 30 days. Temperatures above 45°F may cause the beer to turn sour and become cloudy. Beer dispensers that accommodate several sized kegs are great because they provide you the flexibility to tap the size keg you plan to use within a 30-day period.
