Wasn't looking to get into an argument. You are welcome to disagree. However, your response was quite rude and completely incorrect.
I didn't recommend a tour company. Sauvistication is an informational website for navigating Bordeaux's wineries. It is new and is gaining a following with wine connoisseurs like myself. I used it this year.
I have used the tour companies as well. It is understandable why some people may want to use a guide, but I didn't recommend it because it is much more expensive, and many of them are more geared towards a less knowledgeable crowd. If you are going to look at tour companies, look at Bordeaux Wine Trails and Ophorus in addition to the one Kimberely recommended.
Safe Travels!
