A seasonal beer usually has a short life. Old Potrero’s 2026 Christmas Spirit has taken a much longer route to the glass, turning a San Francisco Christmas spiced ale brewed in 2015 into a ten-year whiskey.

The new release comprises 492 bottles at 100 proof. Its defining step happened before maturation: the ale was distilled twice in copper pot stills, then placed in barrels that had already held Old Potrero Straight Rye Whiskey. This is a spirit made from beer, rather than an ordinary whiskey given a brief finish in a beer-seasoned cask.

That distinction places the bottle within the broader conversation around beer-inspired American whiskey, while giving it a specific local starting point. San Francisco’s brewing culture supplies the raw material; a decade in previously used rye barrels supplies the second chapter. The barrel history matters as much as the holiday label.

The bottling retains the Christmas Spirit name and a neck tag with space for a sender and recipient. Its 50% alcohol content gives the release a substantial bottling strength, without making a claim about cask strength or added flavoring.

Old Potrero lists the 700ml bottle at $139.99. It is available in California and Massachusetts, with online shipping to eligible states. The seasonal presentation is familiar; the conversion of an actual spiced ale into a long-aged spirit is the more interesting reason to pay attention.
