We took the bus from downtown SF across the bay with the plan to visit at least 2 of the 4 wineries on Treasure Island. Our first stop, Treasure Island Wines was as far as we got. One of the four winemakers, Derrick, was pouring and he was so welcoming! We tasted 9 wines and they were all very very good! A delightful surprise. Spent so much time there chatting and enjoying the tastes that we didn't have time to stop anywhere else!
