While bottles are rocking in Napa Valley, Fogbelt Brewing Company breaks out the barrels for its second annual BarrelRock music and beer mini-fest. BarrelRock is highlighted by the release of four new barrel-aged beers, including a sour beer that sat in Zinfandel wine barrels and a cinnamon-cream ale kept in peach brandy barrels. Barbecue complements the brews while you dance the day away with a diverse music lineup featuring laidback reggae rock from Clear Conscience, alt-pop licks from Lungs and Limbs and more. Get a taste of the barrels on Sunday, May 27, at Fogbelt Brewing Company, 1305 Cleveland Ave., Santa Rosa. Noon to 9pm. Free admission. 707.978.3400.
