Show Notes

Jim Shannon and Todd Ritter head just down the road to Frankfort, Kentucky, for a hands-on blending session at J. Mattingly 1845 Distillery — located directly across the street from Buffalo Trace on Wilkinson Boulevard. Joining them is Aaron Mulally, J. Mattingly's head whiskey blender, who walks them through the distillery's signature Blend Your Own experience inside the newly expanded 25,000-square-foot facility. Aaron shares the philosophy behind J. Mattingly's crafting process — where charred and toasted oak staves are added to barrels to accelerate maturation and push whiskeys toward unique flavor profiles — and explains how regional food culture informs every blending decision the team makes.

On the Tasting Mat:

  • Barrel 1261 — J. Mattingly 1845 MGP Bourbon (Single Barrel, ~117 Proof): A 7+ year MGP sourced bourbon distilled from a 75% corn, 21% rye, 4% malted barley mash bill. Rich and chewy with white fruit and overripe tropical notes on the nose, settling into a coating mid-palate experience with a light bitter finish reminiscent of banana peel. (00:35:31)
  • Barrel 1189 — J. Mattingly 1845 MGP Bourbon (Single Barrel, ~119 Proof): Same 75/21/4 MGP mash bill at 119 proof. A brighter, lighter nose with hints of honeysuckle and floral spring notes. On the palate, vanilla wafer sweetness dominates with buttery texture and classic caramel and ginger notes. (00:36:58)
  • Barrel 1221 — J. Mattingly 1845 MGP Bourbon (Single Barrel, ~117 Proof): 117 proof expression from the same MGP mash bill. A lighter, mintier and herbaceous nose gives way to a fast-moving palate that rushes toward the back with cherry and pop rocks-like effervescence, leaving a dry tip-of-tongue finish. (00:39:00)
  • Barrel 1220 — J. Mattingly 1845 MGP Bourbon, Toasted Staves (Single Barrel, ~116 Proof): The lowest proof of the six at 116, this barrel was finished with toasted (rather than charred) oak staves, slow-cooked for hours to draw out sugars. Pronounced notes of smoky marshmallow, vanilla icing, dark raisin, date, and plum cake with sweet cream. The sweetest barrel of the flight. (00:52:25)
  • Barrel 1223 — J. Mattingly 1845 MGP Bourbon, Lightly Charred Staves (Single Barrel, ~118 Proof): A 118 proof barrel treated with lightly charred staves, delivering a savory and woody nose reminiscent of a carpenter shop or Rick house floor. Exceptionally velvety and soft on the palate with sage-like herbal notes and a rich, coating mouthfeel that speaks to oak-forward bourbon lovers. (00:54:48)
  • Barrel 1262 — J. Mattingly 1845 MGP Bourbon (Single Barrel, ~119 Proof): Aaron's personal favorite barrel of the six. Dark, savory, and leathery with pipe tobacco and dried dark fruit on the nose. Earthy and complex on the palate, evoking North Carolina tobacco country. A near-complete barrel that works best as either a dominant base or a precise accent in small percentages. (00:57:46)
  • Jim & Todd's Custom Blend — J. Mattingly 1845 MGP Bourbon (Blended, Barrel Proof): A custom blend assembled during the session: 50% Barrel 1261 (white fruit base), 20% Barrel 1223 (velvety savory), 20% Barrel 1262 (tobacco and dark fruit), and 10% Barrel 1220 (toasted vanilla sweetness). The resulting pour is chewy and unctuous with a full-palate impact — front, middle, and back — combining dark earthy tones with bright sweetness, excellent legs, and a finish worthy of a cigar pairing. (01:13:48)

This episode is a rare inside look at the art and science of whiskey blending. Aaron pulls back the curtain on how J. Mattingly uses regional palate preferences, barrel stave treatments, and creative ratio work to craft expressions that go far beyond what any single barrel can offer. Whether you're a seasoned bourbon enthusiast or just beginning to explore the trail, the Blend Your Own experience at J. Mattingly 1845 is one worth putting on your itinerary — especially when Buffalo Trace is already on your list and you find yourself just across the street.
