Double Gold Winner at the San Francisco World Spirits Competition! Old Potrero 18th Century Style Whiskey is our attempt to re-create the original whiskey of America. This release was distilled in a small copper pot still at our distillery on San Franciscos Potrero Hill; from a mash of 100% rye malt. Rye was the grain of choice for Americas first distillers; and using a mash of 100% rye malt produces a uniquely American whiskey. We have found that handmade oak barrels—lightly toasted in the traditional manner—impart a wonderfully subtle flavor to our 18th-century-style American whiskey. In the 18th century; barrels were made by heating the staves over a fire of oak chips; allowing them to be bent and formed into a barrel shape. During this process; the inside of the barrel would become toasted —but not charred. For aging; we have chosen several uncharred oak barrels—both new and used —to achieve the balanced complexity that complements this whiskeys traditional heritage.
