Hotaling & Co. has announced the launch of Old Potrero Christmas Spirit, a 12 year old American whiskey distilled from a spiced ale. To create Old Potrero Christmas Spirit, Hotaling & Co. Distillery took an iconic San Francisco Christmas Spiced Ale from 2011 and distilled it twice in copper pot stills, then aged it for 12 years in once-used Old Potrero Straight Rye Whiskey Barrels.
