I am looking to do 2or three short day trips outside of Bordeaux for wine tasting and vinyard tours. In Napa, tours take you to several vineyards, the appointments are pre-arranged, and one just needs to sit back and enjoy the day without needing to drink and drive! I hope to find similar day trips in Bordeaux. I am interested in Entre-deux mers for the white bordeaux and the Medoc for Cabernet Sauvignon. Thank you in advance for any suggestions.
