So I had the opportunity to chat with the owner of a truly excellent beer bar and restaurant. He mentioned that he had a 1993 Cantillon Gueuze in his cellar. This got me thinking... if I want to have a 20 year old version of any beer I better get it soon so I don't have to wait even longer. I'm 23 right now and I like the idea of holding onto something very special for a very long time. Not forever, but maybe in 20+ years for a very special occasion. So my question is what beer would you buy right now to hold on to for that long?
