We arrived an hour before a tour was scheduled to start, but Debbie was willing to give our family of three a tour immediately. It cost $7.50/adult and we sampled 5 wines and had a brief walking tour around the building. If we hadn't had the walking tour, the wine sampling would have been complimentary.
Since we only went to one winery, I don't have a comparison to make, but I wonder if I would pay for a tour to every winery I visited.
We appreciated the courtesy that was extended to us and enjoyed the grounds, especially sitting outside and sampling the wine.
