Sparrow Lane Vinegars, located in Napa Valley, was founded in 1998 by current owners Phil and Denise Toohey. The vinegars are an all natural product, made exclusively with varietal wine grapes grown in Napa and Sonoma counties. The word vinegar itself stems from the French term ‘vin aigre’ or sour wine. The vinegars are made by the traditional method of aging in small oak barrels. Careful attention is given to the acid level of these vinegars to make them flavorful and approachable.
