Top notch experience. Romain strikes the perfect balance between fun/friendly and professional/educational. His English is perfect, and he’s quite adept at explaining concepts in an easy to understand manner. Agree with other reviewers that he’s extremely patient and accommodating - will answer any and all questions you have. He even pulled over so we could take pictures of sheep in the vineyard, and later dropped us off in the town center for lunch after the tour. Absolutely would recommend to friends, family, or colleagues. Thank you Romain for a great day!
