We opened a 3L bottle of 2009 Double Bastard at our company party last summer. It was incredible. Oddly enough, the 3L bottle of 2008 Hennepin was better.
Slight necro, but I just found a bottle of this that I was given 4-5 years ago. It's never sat in the light, but it has sat in 120+ degree temps. How is that going to affect the flavor?
