I took a 19 year old barley wine to the brew your own seminars in Asheville in 2019. I shared it with Denny, Drew and Marshall during the session they were presenting. It was in a flip top grolsch style bottle that had been stored under our stairs at room temperature in Houston. At times this also meant room temps in the upper 80s when we were traveling during the summer. A friend babysat this beer at his house when we were out of the country for a year. The beer was tasty. Oxidized but still pleasant. Light on carbonation. It was better when it was younger but aged well, which I am also attempting to do.
