Ok, just brewed a rather large barley wine today that won't be cracked until this Christmas. After primary/secondary fermentation and racking into a Corny, how do I age? Just flush with CO2, put on enough pressure to keep a blanket and wait until Thanksgiving to carbonate? It will be sitting in the basement (in the 60s) from now til' then. This is my first barley wine but I assume the volumes of CO2 are on the low side based on my experience in the London pubs during the Christmas holidays.
