So I had a chance to chat a little bit with Brendan Moylan last night, owner and founder of Moylan's Brewery and Marin Brewing Co.
I'm a big fan of Old Blarney Barleywine and their other beers and I am going to brew a barleywine at some time over the next few weeks, so I decided to ask him how long he prefers to age a barleywine before drinking them and his answer was somewhat surprising.
His response was this:
"Although I do like to occasionally drink a 5 or a 10 year old barleywine, I prefer to drink mine at 6 months so that I can still taste the hops."
I guess that answers my question about how long I should age mine before popping one open.
