There may not be as many fall festivals as summer festivals in Oakland, but there are few coming up. Given how we didn't have much of a summer, and now we're getting even warming than normal for September (which frequently has the warmest weather at the start of the month), it's a happy coincidence that several of them feature beer.
First up is Life is Living on Sunday, October 3rd. It's an arts and eco-justice festival. Although it's held in Defremery Park in West Oakland, it starts with a Red, Bike and Green bike ride from Coliseum BART. Oakland Local has a full write-up on it.
Then on Saturday, October 9th is Oaktoberfest in the Dimond. Last year's was a lot of fun, and hopefully they'll do a better job balancing tickets vs. available beer.
Finally, on Saturday, October 23rd is Brats and Beer at Linden Street Brewery, and is a fundraiser for Oakland: "All proceeds benefit BACS' Thanksgiving holiday food basket distribution, and the Oakland Rotary Community Endowment." Despite the name, they will have vegetarian options for food, too.
