This 1996 “Old Blue Granite” barleywine ale, from Blind Pig Brewing in Temecula, CA (no longer in business). I stashed a sixpack of it in the cellar when it was released and after 22 years it’s still excellent. Any harshness from the hops has mellowed away, leaving a polished and earthy brew.
I still have a bottle left, and a big set of Sierra Nevada Bigfoot from subsequent years. I 'm a little sorry I stopped saving a sixpack a year of Bigfoot about ten years ago.
