Old Potrero California Cellar Series #04 Almanac Beer Finish (700mL) is a San Francisco straight rye whiskey from Old Potrero. It was aged for 6 years and 6 months in new charred American oak, then finished for 5 months in Old Potrero rye barrels that had held a custom Almanac Beer Co. imperial stout for 8 months. The complete maturation totals 6 years and 11 months. This California Cellar Series release is bottled at 57.5% ABV / 115 proof in a 700ml bottle.
Old Potrero describes rich chocolate, vanilla, and barrel-rickhouse character on the aroma. Caramel, roasted malt, and spiced apricot shape the palate, followed by a viscous, long finish with deep stone fruit and rye spice. The stout-barrel treatment links the distillery’s malted-rye whiskey with Almanac’s malt-forward imperial stout, adding roasted and cocoa-toned dimensions while preserving the whiskey’s rye character.
