Seems like we all know a home brewer out there who endlessly tweaks his personal recipes for ultimate refreshment. This year, the Petaluma Downtown Association brings together nearly 70 home brewers from around the area for the inaugural Sonoma County Home Brewers Competition, and you get to be the judge. Sample suds from the proud pourers and vote for your favorite. The top beer maker gets the chance to have his or her recipe brewed by 101 North Brewing Co. and distributed across the land. Bites by Mountain Mikes Pizza, and local food trucks accompany the tastings. The Dixie Giants provide the tunes for the competition taking place on Saturday, May 23, at the Veterans Memorial Building, 210 Lakeville St., Petaluma. 11am to 4pm. $25. petalumadowntown.com.
