Here's a set of questions for everyone. I have a 15 gallon rye barrel. I am going to fill it with barleywine. I think, with the equipment on hand, I can make 10 gallons. Should I try to make 15 gallons in order to minimize the head space? Would oxygenation be a problem? Should I go from primary into secondary, then into the barrel, or primary, into the barrel for a week, then keg it? I'm thing primary, then a cold secondary, followed by a week in the barrel, then into kegs. Any thoughts? Thanks.
