OK, so we are clueless when it comes to wine. As in: go to the store, pick out an interesting label, and you're done.
Even so, our friendly, helpful and accommodating driver, Mark, took us to four great places and we soon caught up. Our favorites for both wine and helpfulness of the staff there: Flora Springs and Tudal Winery.
Also, it turns out that Platypus Wine Tours gets all the cool people on their tours, so we would have had a great time just meeting new people even if wine was not involved.
Loved it. Would do it again next time.
