The Brooklyn Beer Experiment, I picked up a card letting me know that 1) Brooklyn is lacking in home brewing stores, and 2) two chefs are trying to do something about this! Though I have never tried to home brew anything, I know folks who have and assumed there was some store they were acquiring their hops and barley from. Apparently not.
Though they don't have a space yet, they do have a blog, www.brooklynhomebrew.blogspot.com. I know I'll be checking back often, and so should you.
