Angels Envy Kentucky Straight Bourbon Whiskey Finished in Port Wine Barrels is unlike any bourbon youve tried. Aged four to six years in new American White Oak barrels, we then finish the bourbon for up to six additional months in Port casks, imported from the Douro region of Portugal. This versatile flavor profile can be enjoyed neat, on the rocks, or in a cocktail. It makes the perfect gift or addition to any bar cart.
