I have had Duvel... (I still know where to get it locally)...very good stuff. But I've also had stuff like Bios Copper Ale and Rodenbach and several excellent Trappist brews. Westmalle & Orval are excellent, but possibly the best single beer I remember was a *fresh* bottle of Chimay blue top about 15 years ago.

I spent about an hour today choosing several IPAs from among maybe 25... including 6-7 I'd never heard of. (And I did get more 90 minute Dogfish Head)

I do have one treasure hidden away... a small bottle of the original Thomas Hardy's Ale from 1993. I drank a 1987 a couple of years ago, on my birthday. It was difficult saving it for 25 years, but it was delicious. I 'may' keep this one for 2-3 more years... but I want to be able to appreciate it, and I am aging too!
