I've been making a blackberry melomel and it was in the primary 3 weeks then I racked the blackberries onto it and left it for 4 weeks. I just racked it off the fruit into a 5 gallon carboy for bulk aging. There's exactly 4 gallons of mead in the 5 gal carboy. Should I worry about oxidation during the bulk aging? I plan to leave in at least 8 months. Would it be better to bottle and age it that way?
