To contribute to the cause, you just log on to the site and click "Fund a Beer." From there, you'll have the choice to select how many you'd like to pay for, whether it's one ($7.50), two ($15), or an entire six pack ($45). Your contribution is then banked and available to be redeemed at two different DC-area craft breweries: Atlas Brew Works or DC Brau Brewery.
Any federal employee who's over 21 and has an ID proving as much can stop by at any time and score free beer. In fact, they can drink as much as they want, since there's no limit on how many can be redeemed (as long as there are beers that've been paid for to be consumed). Seems like there's plenty to go around at the moment, too, since more than 500 beers have been donated in the day or so the site has been live. As of this writing, only 13 have been redeemed so far.
We may not all agree on everything these days, and DC may be a cesspool of incompetence and partisanship, but it's tough to argue with any initiative that promotes free beer for those in need.
