Les Vignerons d'Estezargues is the only wine-cooperative in France (in the world?) to make "natural" wines: wild yeasts, no enzymes, no filtering, & minimal sulfites (only added during bottling, not during fermentation)... just the grapes! Great for serving wine by the glass, for parties, picnics, or for people who want only a glass of wine a day (the conservation is much longer than for bottles once opened). And it is light to carry. The box also has a much smaller carbon footprint than bottles because it is so light to ship.
