Flavor Profile Differences
Sweetness is where these two part ways.
- Old Grand-Dad Bonded: A bonded 100-proof high-rye bourbon for the price of a mixer, and one of the great bargains on the shelf. Cleaner and less overwhelming than the 114 while keeping the peppery rye backbone.
- 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 Old Grand-Dad Bonded if you want a bonded, high-rye workhorse at mixer money.
- Go with Penelope Architect if you want a four-grain bourbon with a French oak finish that adds berries and warm spice.
