Old Potrero Single Malt Whiskey is our attempt to re-create the original whiskeys of America. Distilled in a small copper pot still from a mash of 100% rye malt. It is aged for one year in new, uncharred , oak barrels at our small distillery on Potrero Hill in San Francisco. Already delightful, Old Potrero's is certainly a young whiskey, and it seems likely that whiskey was often consumed as young as this in the early days of American distilling, when eager farmers savored the fruit of their labors. Probably no one will ever know every detail about how the first whiskeys were made along the Atlantic Coast in the 18th century - written records are very scarce - but for many reasons it seems likely that they were made, like this one, from a mash consisting entirely of malted rye. Rye was the grain of choice for American's first distillers, and when you taste Old Potrero you will see that using a mash of 100% rye malt produces a whiskey with a wonderful character.
