Penelope Project X Bourbon Sherry & Cognac Cask Finish 'Formula XO'

Penelope Project X 'Formula XO' is a limited expression from Penelope Bourbon — a straight bourbon with a dual cask finish in sherry and cognac barrels, combining the dried fruit and warm spice of sherry cask influence with the brandy richness and subtle floral character of cognac cask finishing to produce a layered, complex expression unlike anything else in the Penelope lineup.

The Project X series from Penelope explores experimental and unconventional finishing approaches. Formula XO — the name referencing the highest age designation in cognac production — uses both sherry casks and cognac barrels as finishing vessels, layering two very different wine and spirit cask influences over the American whiskey base. The result is a Penelope expression with significantly more European character than the standard lineup. Distilled in Lawrenceburg, Indiana.

Frequently Asked Questions

What does cognac cask finishing add to bourbon?

Cognac barrels carry the residue of aged French brandy — floral, fruity, and subtly spiced with a refined European character very different from American oak or sherry cask influence. Combined with sherry cask finishing, the cognac barrel adds a layer of brandy richness and floral complexity that makes Formula XO one of the most European-influenced American whiskeys available.
