How much ullage in a 9 gallon container?


In a 9 gallon barrel is the amount of beer exactly 9 gallon or do they allow 10% ullage


There should be more than 9 gallons in a 9 gallon cask. There will be approx 4 pints or so of finings, bottoms etc left in the container when 9 gallon of good ale has been removed.

Do you have a better answer? Leave a reply or an opinion
