Welcome to California! This weekend may cool down weatherwise, but an icy mug full of beer quenches your thirst and gives you that internal “cool” feeling like no other. Beer festivals this weekend capitalize on the summertime heat phenomenon by offering cool samples, sips and specials. Silicon Valley Beer Week Pucker Up Sour Fest 4.0 is one such event where you can visit a variety of participating breweries and restaurants to enjoy the finest beers on tap or in the bottle July 25-August 2, 2014.
