Old Potrero 18th Century Style Whiskey is the attempt to re-create the original whiskey of America. This release was distilled in a small copper pot still at the Olld Potrero 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. The spirits in this bottling were aged in new un-charred oak barrels. The youngest were aged for 2 years 5 months and the oldest for 3 years 9 months, a blend of balanced complexity that expresses Old Potrero's traditional heritage.
