When I drank a 2007 back in 2014 I was shocked that it had a twist off cap. It was slightly oxidized but it honestly tasted like someone dropped a shot of whiskey in my glass. I couldn't believe how hot it still was. Had 2 bottles of 2008 that I drank in 2013 and 2014. I couldn't believe how well they held up. I have had a lot of beers that haven't aged well but BCBS is not one of them.
