Oakland was at one time one of the largest beer brewing cities in the country until Prohibition ended the city’s golden glow.  But thanks to several microbrewers it is buzzing again. For the last few years Oakland and Berkeley have emerged as a craft beer goldmine and the location of some of the best breweries, brewpubs and beer bars in the Golden State.  Take a peek at some of the great breweries you could visit on your Golden West tour on October 15.
