The Walnut Creek Chamber Art & Wine Festival celebrates its 25th year this weekend. As the area’s leading event of the summer, some 100,000 visitors will call over the two days and enjoy tasting tasting select wines, brand name beers and local micro-brews. Vintage and boutique wines can be tasted in the Premium Wine Tent. If you’re feeling active, don’t miss the grape stomp. What’s particularly encouraging to see is that designated drivers will be given free soft drinks and a special souvenir glass; hats off go to Subaru for that.
