Penelope Barrel Strength is bourbon in its purest form. Completely uncut and non-chillfiltered, our barrel strength bourbon is just as delicious and even more powerful than our signature Four Grain blend.

Each batch of our Barrel Strength is blended from three bourbon mash bills and aged in hand-selected new American oak barrels, imparting notes of caramel syrup and subtle barrel char and pushing the boundaries of our Four Grain’s balanced flavor profile.

Aroma: Pecans, dried apricot, and hints of vanilla
Forward Notes: Smooth caramel syrup, brown sugar, subtle barrel char, and hints of butterscotch and crème brûlée
Body: Carmel, toffee, leather and pecans with a hint of orange zest
Finish: White pepper, cinnamon, and brown sugar with lingering caramel

Mash Bill: 82% Corn, 8% Wheat, 7% Rye, 3% Malted Barley
