A friend sent me a batch 81 recently. Though their beer is top-notch, their site is pretty bootleg. Rather reminds me of 1999. Accordingly, their vintage list only goes to 59. Anyone happen to know when this was bottled? Also, don't be afraid to jack this thread to ask about batch numbers that you have, assuming they're after 59. Before, 59, not only are you extremely lucky, but you can find it here: http://www.hairofthedog.com/adam_vintages.html. Thanks, guys.
I'm not sure how often they put out new batches of Adam, but IIRC, the newest batches of Adam I've seen around are 83 or 84. So, I'm guessing 81 is sometime mid to late 2011. There is a thread dealing with this topic in the Northwest forum, but nobody seems to have a good answer. According to one post in there, the HotD website is supposed to be under construction, and all of the updated batch info will be available "soon."
