We recently took the three hour Grand Cru tour with Safari Tours-Bacchus Tours. Our guide was Laurent. She was very knowledgeable of the vineyards near Beaune, and of the wine making process. We stopped at a lovely winery and tasted eight wines. We had a very enjoyable three hours with Laurent and two other people, in her comfortable van. Though we could have driven into the countryside ourselves, we would not have known anything about the history, the wines, or the process of wine making. It was definitely a great choice to spend an afternoon with Laurent. I suggest you ask for her when you book your tour.
