Flavor Profile Differences

Barrel influence is the main separator.

  • Barrell Bourbon (Batch Series): Barrell blends sourced barrels from multiple states and bottles at cask strength, and the batches differ enormously. At their best they show a tropical fruit note that almost nothing else in bourbon delivers.
  • Penelope Architect: Penelope's four-grain blend finished with French oak staves chosen for their tannin. The French oak adds berry, cherry and warm spice to a vanilla-heavy base.

Which One Should You Choose?

  • Go with Barrell Bourbon (Batch Series) if you want an adventurous, cask-strength blend and you accept that each batch is its own animal.
  • Go with Penelope Architect if you want a four-grain bourbon with a French oak finish that adds berries and warm spice at a lower price point.
