Our take on America’s original whiskey. Old Potrero marked the return of pot distilled rye whiskey to the United States. Distilled using a small copper pot still at the Hotaling & Co. Distillery on Potrero Hill in San Francisco. Distilled from 100% malted rye mash bill. Matured in 24 month air dried new charred fine grain American white oak barrels for at least 4 years 6 months.
