5.8% acidity There are no shortcuts to making handcrafted vinegar. About The Taste: We marry the sweetness and complexity of wine grapes that have been left on the vine to concentrate the natural sugars, with the bright and crisp acidity of traditional Orleans Method wine vinegar - in Italy this type of vinegar is referred to as Agrodolce, 'sweet and sour.' To achieve this, we use 100% North Coast Zinfandel when the brix (sugars) are over 26 - very concentrated and almost port-like. We then ferment the sweet grapes into wine before adding it to oak barrels with the addition of some 'mother' (the starter) for its traditional, slow journey to becoming red wine vinegar. The garnet, port-like color of the Agrodolce gives way to lots of plum and fresh berry overtones and a pleasant, crisp finish. Use where a richer profile of vinegar is called for and a more complex taste is needed
