Old Potrero Single Malt Straight Rye Whiskey is a part of our endeavor to re-create the original whiskey of America. This release was distilled in a small copper pot still at our distillery on San Francisco's Potrero Hill, from a mash of 100% rye malt. Rye was the grain of choice for America's first distillers, and using a mash of 100% rye malt produces a uniquely American whiskey. This straight rye whiskey was aged in new handmade charred oak barrels. In traditional barrel making, the cooper heats the staves over a fire of oak chips, allowing them to be bent and formed into a barrel. During this process, the inside of the barrel becomes lightly toasted. By the early 19th century, coopers had learned that if they allowed the heat to continue, the inside of the barrel would burst into flames and become charred. At Anchor, we have found that handmade oak barrels charred in this traditional manner impart a rich color and unique character to our rye whiskey. We hope you will enjoy comparing it to our other releases. The Anchor Distilling Company is dedicated to creating very small batches of traditionally distilled spirits of many types and styles.
