Flavor Profile Differences
The gap between these two is mostly about spice.
- 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.
- Zackariah Harris: A bottom-shelf Kentucky straight bourbon, mostly sold in liters and handles. Simple caramel and oak with a short, warm finish.
Which One Should You Choose?
- Go with Old Grand-Dad Bonded if you want a bonded, high-rye workhorse at mixer money with more proof behind it.
- Go with Zackariah Harris if you want a simple Kentucky bourbon for mixing at a slightly lower price point.
