Old Potrero CHristmas Spirit Whiskey NOSE: Spiced fruit cake, candied orange peel, vanilla, and hints of evergreen or pine. PALATE: A balance of sweet malt, roasted barley, baking spices (cinnamon, nutmeg), and fresh ginger. FINISH: Long and warming, featuring notes of roasted malt, light oak, and a lingering soft pine twist. Old Potrero Christmas Spirit is a limited-edition seasonal whiskey produced by San Francisco's Hotaling & Co. (formerly Anchor Distilling). It is uniquely crafted by double-distilling Anchor Brewing's Christmas Spiced Ale in copper pot stills and aging the resulting spirit in once-used Old Potrero Straight Rye Whiskey barrels.
