Penelope Barrel Strength Bourbon is a bold, unfiltered expression crafted using the brand's signature four-grain mashbill. Each batch is blended from three distinct bourbon mashbills, aged in charred new American oak barrels, and bottled completely uncut and non-chill-filtered at barrel strength — approximately 57% ABV (114 proof) — preserving the full depth and natural character of the spirit.

Every barrel is hand-selected and blended into a single batch, resulting in a complex, full-bodied whiskey with rich notes of caramel, vanilla, and warm oak spice. The finish is long and warming, characteristic of high-proof bourbon. Produced by Penelope Bourbon and distributed by Luxco Inc., this expression is a standout choice for enthusiasts who seek an uncompromising, authentic barrel-proof experience.
