Flavor Profile Differences

These two land very differently on the palate for heat.

  • 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.
  • Jefferson's Ocean Aged at Sea: Bourbon that spends months rocking in a ship's hold. Each voyage tastes a little different, but expect caramel and dark sugar with a savory, faintly salty edge from the trip.

Which One Should You Choose?

  • 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.
  • Go with Jefferson's Ocean Aged at Sea if you want a conversation-piece bourbon with a savory, slightly briny twist from aging at sea.

Best enjoyed neat, old-fashioned (Penelope Architect); neat, rocks (Jefferson's Ocean Aged at Sea).
