Bordeaux takes its wine seriously, and the bar scene reflects that — a good bar here is usually also a good wine bar, with a list organised by appellation and staff who know what they're talking about. The Chartrons and Saint-Pierre quarters have the highest concentration. For the full range of Bordeaux appellations in a low-key setting, the Bar à Vin du CIVB on the Cours du 30 Juillet is the obvious starting point.
