New to craft beer? Want to try an ounce or two of several different styles — from the standard to the exotic — without committing to an entire glass? First Draft offers the freedom to do all of that. The place works like this: Walk in and lay down a credit card and your ID in exchange for a card or bracelet that operates the taps. Then walk over to the wall of forty taps, swipe your card and pour a little, or a lot, of any beer into your glass; you'll be charged by the ounce. Then clean your glass and try something else. Want to sample the latest Portland pale ale, a new sour, an obscure beer from a Colorado mountain town? Do it here.
