Old Potrero California Cellar Series #02 Sonoma Portworks Finish (700mL) begins with toasted-barrel rye whiskey aged for 5 years and 10 months in new, fine-grain toasted American oak. It then spends 17 months in Sonoma Portworks Petite Sirah port barrels, bringing total maturation to 7 years and 3 months. This exact 700 mL California Cellar Series release is bottled at 56.8% ABV / 113.6 proof.
Old Potrero lists deep caramel, rich vanilla, cooked fruit, and cacao on the aroma. Sweet rye, spicy cinnamon, nuttiness, and bright cherry wood shape the palate, followed by grape-cola character, grape-leaf tanginess, and a warming rye finish. Sonoma Portworks attributes cherry, dried fruit, and cinnamon-spice influence to its used Petite Sirah port barrels. The bottle label records the initial 5-year-10-month maturation and the separate 17-month finish, preserving the complete chronology for this single high-proof rye whiskey.
