Quite a new development the wine bars of Bordeaux are all the fashion now:
Aperitif at the CIVB Maison du vin (opposite the tourist office), Bar à Vin open from 11 to 10pm (not Sundays or Bank Holidays) for a range of over 20 different appellations. Ask for a tasting sample rather than a glass so you can taste a large range and still make it out of the door.
Le Wine Bar Rue Bahutiers (near old town) run by very chatty and sociable Giancarlo for an Italian touch to your time in Bordeaux
Aux 4 Coins du Vin in the old town has a wide range of wines, not just Bordeaux (enomatic machines)
In a different area of Bordeaux, the trendy Chartrons district, is the atmospheric Wine & Soul wine bar (23 rue du couvent).
Not forgetting the ultra modern Max Bordeaux in Cours de l’Intendance with your card help yourself to first growths and others from 1€/25ml to 25€ for the tops! Range of 40 classified wines served from enomatic machines
