2 Passports to over 50 wineries in Santa Cruz Mountain Winegrower Association. The third Saturday of January, July, November and December open up their vineyards just to Passport members where they pour special wines or barrel samples. Once you visit the winery, they will give you a commemorative stamp.  The Passport expires once you have visited all participating vineyards.  Take as long as you like to see this beautiful area during different seasons and years.  Take home a couple of bottles from those that you like, too!
