It is thanks to a happy coincidence that we owe the vinegar...Leave a bottle of wine open, it will turn sour! Refreshing drink, natural antibiotic, preservative or condiment, vinegar has many qualities. Tasty, artisanal vinegar goes wonderfully with salads: lettuce, watercress, baby spinach, tomato, endive or mixed salad... Are you more of a carnivore? It deliciously deglazes meat...
