Not taking a tour of a winery seems almost like a faux pas if visiting Bordeaux. Unlike the California wine regions, you cannot just drive up to the wineries and do a tasting and take a tour; you have to make reservations. Even so, only a few of the châteaux provide insight into their production. The tourism office offers variations of tours ranging from half a day to full day as well as various sizes from private to small groups of 8 or less to large groups that can be up to 50 people. The wine tour that we took, which I would recommend, consisted of a total of 8 people to the Graves region just south of the city. Held in both French and English, we toured two wineries Château Haut-Bailly and Châteaux Carbonnieux. They explained the different stages of winemaking, demonstrated the proper way to taste the wine, and answered any and all questions. If you are interested in investing in this region, it costs a pretty penny: approximately one million euros per hectare. Ouch! Nonetheless, you can save those millions for later and take the tour instead. For more information on some tours in Bordeaux, click here.
