I’ve been considering doing a few smaller experimental batches and I’ve been wondering, would force carbonating 3 gallons of beer in a 5 gallon corny keg be a waste of CO2? In particular I’m trying to decide wether or not it would justify purchasing a 3 gallon keg specifically for these batches. 3 gallon kegs are even more expensive than 5 gallon kegs most places I see them, and I already have a few extra 5 gallon corny kegs I could use if it wouldn’t make much of a difference.
