Barton & Guestier B&G Réserve Cabernet Sauvignon is a red wine made from 100% Cabernet Sauvignon grapes, sourced from the Languedoc-Roussillon region of France. The wine is produced by Barton & Guestier, one of the oldest wine merchants in Bordeaux. The grapes are grown in vineyards with a diverse range of soils and microclimates, which impart complexity to the wine. After fermentation, the wine is aged for a few months in oak barrels, which adds subtle notes of vanilla and spice to the wine. The resulting wine is full-bodied and rich, with flavors of blackcurrant, black cherry, and tobacco, and a smooth finish.
