I'm not sure why the Reserve is not sold more broadly; it's extraordinary stuff. I do understand that it's a limited production and only seasonally available, commencing some time in late fall to early winter and then ending some time late winter or early spring. If I can get tix to our game (Duke @ UVa; we gave up our season tix somewhere in the middle of the Mike London regime out of a mixture of depression and disgust, the disgust coming from infamously re-seating season ticketholders who had been going to games before the hiring of George Welsh, a decision I'm starting to regret), I plan to go by Blue Mountain Brewery (calling ahead is advisable given the limited availability, if your only reason to be there is to snatch up some Reserve) after a visit to Blue Ridge Pig.

Stores stock whatever they want of what Blue Mountain is producing; Blue Mountain may want to give brew lovers a wider exposure. Hence the live music as well. And the frequent tastings. That is savvy marketing, IMO.
