Spring is officially here! Of course, California doesn't see the drastic changes in temperature that some other states experience, but the rainy season should be on its way out - bringing sunny days that are perfect for exploring some of the world-class wineries that are close to the Silicon Valley area. In fact, our moderate year-round temperatures are part of the reason that Northern California produces such excellent wine! A wine-tasting tour is a great activity to do with visitors or a date, and it's also a fun, easy way to celebrate birthdays with friends.Check out the Bay Area A-List's 2014 winners for the Best Winery in Napa Valley for some great ideas - Frank Family Vineyard tops the list for the 5th year in a row! Don't forget to buy a bottle or two as a memento... or better yet, sign up for the wine club at your favorite winery.If you don't want to go to Napa, there are some great local events as well. The Santa Cruz Mountains Winegrowers Association's quarterly Passport Days event is coming up on April 19th. Your passport for the event will get you access to private wineries, eliminates the tasting fee, and gives you a chance to meet some of the famous Winemakers of the Santa Cruz Mountains. Each winery you visit will be able to stamp your passport; prizes are available for completing your passport! Visit the SCMWA website for more information.Passports are $45 online or can be purchased at participating wineries. View the list of participating wineries here.
