Quite disappointing. The tour itself didn't live up to the hype and review from all others I read up on it. The driver cum tour guide mumbled on the microphone and seemed disinterested in the group from start to finish. He didn't build up aby group dynamic which is essentially the role of a guide (that used to be my job).
The wineries visited were basically cellar door tastings. There wasn't an education or history behind the wine making process or the region, nor did they teach the basics of wine appreciation (what to look for, how to serve, etc.). You just came in and sampled different wines
You're better off hiring a designated driver for the day and go cellar hopping on your own since cellar door tastings are free anyway.
The scrumptious lunch set up was a medley of deli finds. So expect to be served a cold plate of lunch comprising: a cold slice of roast beef, a cold piece of roast chicken leg, pickled shallots, peppers and artichokes, grilled zucchini slices, a cherry tomato on a small bed of greens, 2 slithers if prosciutto, 2 slices of salami, and of course a slice of cheese. The whole group would share 2 bottles of wine between them.
In the end, it's your tour mates who will define the outcome of your tour since your tastebuds would have been botched by the 3rd tasting session anyway. We were fortunate enough to have an awesome group. I used to work as a tour operator myself, so I would know how crucial the tour guide and members plays a role in the whole experience.
I wouldn't hesitate spending more for a more luxurious provider if that would assure a more hospitable experience and less drop-off-bugger-off type of a tour.
