This was a terrible experience. If our guide knew anything about wine, she did NOT share it with us. We went to three average cafes that we could have found on our own and had average wine without an explanation. She wasn't even able to answer our most basic questions about wine. Most disappointing thing we did on our trip! And it was what I was looking forward to the most. Do NOT recommend at all!
This was a fabulous experience! I would recommend it to everyone. Just note they aren't proactive in directions so make sure you ask where the champagne tasting will be on the boat. If you don't, you may miss it!
