Brunos Red Wine Vinegar is a premium product made for those who appreciate a vinegar with ample strength and flavor. This vinegar starts with a red wine blend made from the high quality grape varieties grown in the fertile valleys of California. This wine is then aged in oak barrels to preserve the rich, robust red wine flavor. The wine is converted to vinegar using a slow, natural fermentation. When fermentation is complete the vinegar is tested to see that it meets strength standards (75 grain). The vinegar is then bottled. The finished product is a premium, natural, barrel-aged vinegar with maximum strength, yet retaining the flavor and bouquet of the wine from with it was made. Bruno's Red Wine Vinegar is not only more flavorful, but is also stronger than most wine vinegars and therefore should be poured with a gentle hand. Bruno's Red Wine Vinegar is great in salads, bread dips and marinades. Those who appreciate quality will find it superior to mass-produced, commercial vinegar. Packaged as one, 375 mL (12.8 ounce) bottle. A half case is six (6) jars and a full case is twelve (12) jars.
