I recently found three six packs of Barleywine I made back in March 2009. It's absolutely fantastic. As everyone's said, never wait to brew a barleywine, wait to drink it. The truth is, I generally start drinking mine about 3-4 months after brewing, but I try to limit it until it gets really aged. I strongly recommend you "lose" as six pack of it somewhere in your house. Future you will be very thankful.
