Bougainville
This is a big list, nearly 800 wines, built around classic France with Bordeaux and Burgundy running almost neck and neck at the top and a deep Champagne section anchored by Krug, which alone shows a dozen listings alongside Bollinger and Marguet. Reds and whites are roughly balanced at over 300 each, but the white side is where the real personality sits, with serious Loire Chenin from Guiberteau, Soave from Pieropan, and Austrian heavyweights in Knoll and F. X. Pichler. Italy is well covered too, from Tuscany down to Barolo in Piedmont, and there is a substantial 46 bottle sweet and fortified run for dessert pairings. Note the native pricing starts low, with examples at 15, 19, and 22 EUR, so there are honest entry points despite the blue chip names. The weak spot for service is the glass program, only 5 by the glass, so steer guests who want to explore toward bottles or half bottles. This list rewards a confident drinker who knows French regions and is curious about top tier German and Austrian whites.
