Pictured is Yuba City’s Blues, Brews and BBQs on Aug. 27. The number 27 is lucky for many beer festivals this week. Sierra BrewFest in Grass Valley hits a jackpot celebrating 27 years, on 27 August, with 27 vendors. The event features unlimited beer tastings, food trucks & local restaurants and Bag-O tournament (also known as corn hole or bean bag toss) featuring prizes such as tickets to the 2017 Sierra BrewFest.
