Penelope Rio is a straight bourbon whiskey from Penelope Bourbon's Cooper Series, which highlights the craft of cask finishing using extraordinary barrels sourced from around the world. Rio undergoes a double cask finish — first in American honey barrels, then in new Amburana barrels from Brazil — creating a layered profile of warmth, sweetness, and spice. It is bottled at 98 proof (49% ABV) and is non-chill-filtered.

The mash bill is composed of 74% corn, 16% wheat, 7% rye, and 3% malted barley, giving it a wheated-forward character. On the nose, expect vanilla, toffee, graham cracker, and floral honeycomb. The palate delivers honey nectar, cinnamon sugar, vanilla, and baking spices, with a finish of cinnamon, toasted oak, and baking spices that fades to honeyed pastry. Whiskey Advocate awarded it 92 points.
