There were 52 people on the wine tour with us and it was honestly too many people to group together in one tour. It was an incredibly hot day and the first vineyard didn't have any indoor space, nor any shelter, which meant we stood in the blistering sun in the middle of the day. The second vineyard was slightly better, with a proper wine-tasting area setup indoors. Combined with the fact that the guide wasn't overly fluent in English (mea culpa for not knowing French, I guess), it wasn't great. Friendly enough, though.
