$300. I missed joining by just a couple people, but I've heard from several that it was barely worth it this year. However, a lot of the problems with releases and bottle counts were due to the contract brewing at Funkwerks and moving to Denver.
I have heard the price will remain the same and bottle allocations will be higher now that the taproom is open and brewing operations are expanding. That came from Scott B. who owns Mr. B's Liquor in LoDo. He is good friends with Chad so I am definitely taking the plunge for 2013.
I am also about 80% sure I'm going to buy a Bruery Reserve membership as well.
This is going to be an expensive month.
