You are what you drink, or so the saying goes. So why not skip the watered down Budweiser laced with green food coloring this St. Patrick's Day and grab a real "green" brew instead. In stark contrast to some of the large corporate beer makers, many craft breweries are at the forefront of sustainability. Perhaps by drinking these more local beers you will not only lessen your impact on the environment but also on your head the next morning.
