Old Potrero 15 Year Single Barrel
Distilled using a small copper pot still at the Hotaling & Co. Distillery in San Francisco. Aged in extra fine grain American Oak. The wood was air-dried for 24 months and the barrels were fully toasted and then charred by hand over an oak fire. The mash of 100% malted rye was fermented for four days and then double distilled in traditional copper pot whiskey stills.
