This past summer we drove thru France for 2 1/2 weeks. We enjoyed daily bottles of wine, purchasing them from a wide range of merchants. Two of the wine merchants need special comment. The unsung small wine shop in St Julien was wonderful. The manager was knowledgeable and the prices were fair, with the Chateau Beychevelle marked below the chateau's own prices.
It was a different story with the Rick Steves recommended Vignobles and Chateau shop in St Emilion. The initially pleasant visit ultimately became unpleasant. There is no need to recount the circumstances, but be aware that both the Chateau Magdelaine and the Chateau LaSerre were significantly overpriced, the former priced more than 60% than that obtainable elsewhere [including the internet sellers] and the latter more than 40%. We can only recommend that Rick Steves surreptitiously re-evaluate this recommended merchant and that the wine buyer use their smart phone when in doubt. Don't be as trusting as us!!!!
