We did the full-day tour and it was incredible fun. A full day of too much wine, cheese, chocolate, food and beer. There were about 13 friendly people on our tour, all having a great time, complete with end of day sing-a-long.
It was the hottest day in recent memory, 41C, but the Two Fat Blokes bus was totally air-conditioned and extremely comfortable as was each venue we visited.
Huge thanks to BJ, our friendly, knowledgable and generous host. He ferried us to each location and looked after our clumsy selves (one lady on the tour left her phone at a previous venue and he didn't hesitate to return to pick it up during our next tasting, and I left my iPad on the bus at the end of the day and BJ arranged to have it returned to me at my convenience. Super grateful!)
It really is a great wine tour service and we would do it again.
