Sourfest is here! The 2012 incarnation of Library Alehouse's sour beer party kicks off on September 4th and runs through the 10th. The first night is for Locals Only, showcasing the best bitter beers from nearby. Of course, The Bruery is well represented, but later dates will feature popular Russian River sours, rare Allagash pours and a rounded selection of New Belgiums as well. The event runs for a week, so you'll have plenty of time to pucker up those lips.
