A rye-driven finished whiskey where rum sweetness adds, not detracts.
Wheel Horse Rum Finished Double Mash Whiskey is the kind of expression that shows you its intent right up front. This is not simply bourbon placed into rum casks for extra sweetness. It is a blend of bourbon and high-rye whiskey with secondary finishing for up to two years in three different styles of rum casks. The Spring 2026 release is limited to 1,800 bottles, and at 101 proof with a $44 MSRP, it lands in a spot where the whiskey still needs to be drinkable, flavorful, and useful.
The stated idea is balance: the bold flavor of bourbon, the spice of rye, and the added sweetness and richness of rum cask finishing. In the glass, that intent mostly holds. This reads as a rye-driven, bourbon-backed whiskey where the rum finish adds tropical sweetness and richness without turning the pour into a dessert whiskey. The Palate is the clear strength. The Finish is where the whiskey loses some of its polish, as competing spice notes and a tannic sour note at the tail end interrupt an otherwise successful pour.
Wheel Horse Rum Finished Double Mash Whiskey (Spring 2026) Review: Tasting Notes
Nose – 4.2/5
Herbal rye. Rye grain. Vanilla. Tropical sweetness. Coconut. Sweet oak.
Strengths: Gives a clear first read on the whiskey’s identity. Herbal rye leads, but it does not stand alone. Vanilla and tropical sweetness build around it in a way that feels connected and worth revisiting.
Why It’s Not Higher: Intensity is moderate rather than full. Invites deeper exploration, but it does not fully bloom out of the glass or deliver a force of notes.
Rating Justification: Succeeds because it reflects the whiskey’s intent. Rye is present. Bourbon sweetness has a role. Rum finish adds richness without becoming heavy. Layered. Well-designed, even if it stops short of being truly expressive.
Palate – 4.5/5
Sweet tropical fruit. Tropical spice. Herbal rye. Sweet oak. Baking spice.
Strengths: This is where the whiskey comes together. Opens with sweet tropical fruit and a coating texture. Builds toward herbal rye and tropical spice. Flavors feel connected rather than stacked on top of each other.
Why It’s Not Higher: Does not quite reach a level of exceptional depth or refinement.
Rating Justification: Delivers the heart of the whiskey’s idea and intent. Rum finish brings sweetness and a brightness. Rye gives structure. 101 proof supports the flavors without adding unwanted heat or becoming a distraction.
Finish – 3.4/5
Tropical spice. Herbal rye. Toasted oak. Lingering tropical sweetness. Peppery rye. Tannic sour note.
Strengths: Flavor, structure, and medium length. Notes carry the whiskey’s identity forward.
Why It’s Not Higher: Does not resolve as cleanly as the Palate would lead you to predict. Tropical spice and rye spice begin to compete with each other. Tannic sour note appears at the tail end is distracting.
Rating Justification: It is not weak, but it is the clear limitation. Evolves, which is better than simply fading. Unfortunately, it evolves into competing spice notes before turning tannic and sour at the end and leaves with you with a sour impression.
Value – 4.6/5
At $44, Wheel Horse Rum Finished Double Mash Whiskey is strong Value. This is a limited-release whiskey, built from both bourbon and high-rye whiskey, bottled at 101 proof, and finished for up to two years in three different rum cask styles. More importantly, the whiskey delivers a clear idea in the glass.
This is primarily an enthusiast pour. It is not difficult to drink, and the 101 proof is well chosen, but the layered structure makes it more interesting for drinkers who enjoy rye character, secondary finished whiskey, and a little experimentation. Drink this neat. A rock softens the edges, but the whiskey’s best feature is the way the sweetness, rye, oak, and tropical spice build across the Palate. Dilution risks taking away the very thing that makes it work.
