Can you ferment 1 gallon of beer in a 5 gallon fermenter?
- Can you ferment 1 gallon of beer in a 5 gallon fermenter?
It is perfectly possible to brew 1 gallon of liquor in a 5 gallon container. The main concern is the air over the brew which, some might say, causes "oxidation" and thus produce off flavours in the brew.
- How big of a fermenter do I need?
Your fermenter should be at least twenty per cent larger than the quantity of beer you plan to brew. For example, for a 20 litre (five gallon) batch of beer, you need a fermenter with a capacity of at least 24 litres (6 gallons).
