The Hogtown Brewers homebrew club down in Gainesville, Fla. goes batty each October for the opportunity to show off their brewing chops and help raise funds for a unique nonprofit organization in their area: the Lubee Bat Conservancy.

ReBrew is a homebrew competition at the annual conference for the Georgia Association of Water Professionals (GAWP) that takes place every year in Savannah, Ga. It promotes awareness of reusing of this valuable resource for brewing.
