Overview: If the Garrison Brothers single barrel is the bottle that started my bourbon journey, Cowboy Bourbon is the one that showed me how far the distillery could push the format. This is Garrison’s flagship — an uncut, unfiltered annual release built from their best barrels, and priced like the statement bottle it is at around $250. The 131.3 proof on my label pins it as the 2020 vintage. It’s a Texas bourbon that drinks like a dessert course someone left in a charred barrel, and I mean that as a compliment.

A quick note on timing: this is the 2020 annual release, but I didn’t get my hands on it until late 2021 — which is the story below.

How I Found It: This came through a club allocation, and it’s a fun one. In late 2021, the whiskey club I belong to secured a few bottles from a distributor’s vault — top-tier accounts occasionally get access to back-stocked cases of previous years’ releases, and Cowboy Bourbon is exactly the kind of bottle that gets squirreled away. What makes it mean a little more to me: our club actually had the chance to sit down with master distiller Donnis Todd during a private barrel-selection session. Tasting a bottle after meeting the person who hand-picked the barrels behind it changes how you drink it. This one carries some weight on my shelf beyond what’s in the glass.

Age: NAS (a blend of roughly 5- to 6-year-old barrels — old for Garrison, given the Texas climate)

Proof: 131.3 (65.65% ABV)

Mashbill: 74% Texas corn, 15% soft red winter wheat, 11% malted barley

What Makes Cowboy Bourbon the Flagship

I covered the mechanics of why Texas bourbon ages so differently in my single barrel review — the short version is that the brutal Hill Country heat cycles the spirit in and out of the wood fast, extracting hard and aging quickly. Cowboy Bourbon is what happens when Garrison applies that process to only their standout barrels.

Donnis Todd walks the Hye, Texas rickhouses hunting for what the distillery calls “piggy bank barrels” — the rare casks developing so well under the sun that they get pulled from the standard lines and held back for extended aging. The trade-off in Texas is steep: evaporation losses here can be enormous, far beyond what a Kentucky rickhouse sees, so what’s left in these barrels after five or six years is concentrated to a syrup. The result is dense, dark, and intense — but the whole point of the selection process is to find the barrels that get there without tipping into bitter, over-oaked territory. On this 2020 release, the curation shows.

Nose: At 131.3 proof you approach the glass with some respect, but the 2020 batch hides its alcohol well. It opens rich and sweet — warm monkey bread, gooey cinnamon rolls, and freshly tanned leather. Give it time and dark-chocolate-brownie-batter shows up, backed by dense molasses and baking spice: clove and cinnamon-baked apples. It smells more like a bakery than a barrel-proof bourbon, which is the Garrison signature at its best.

Palate: The texture is the first thing that hits — massively viscous, chewy, and syrupy, coating the whole palate. It’s sweeter than the higher-proof Garrison picks I’ve had: dark molasses, brown sugar, and something close to Dublin Dr Pepper land on the center of the tongue. Mid-palate the wood takes over, as it always does with Texas bourbon — smoky oak char, tobacco leaf, and a rich cocoa note. It’s bold and uncompromising, and at times tastes like a charred barrel stave wrapped in burnt sugar. But the extended barrel selection keeps the oak from going astringent. A few drops of water pull even more sweetness forward.

Finish: Long, dry, and slowly evolving — the classic Texas hug that keeps going for minutes. The chocolate and molasses sweetness recedes first, leaving behind seasoned cedar, leather, dry espresso grounds, and lingering barrel char. It closes with a soft return of vanilla bean and sweet pipe tobacco. The finish is where the extra age earns its keep: it’s complex and layered rather than just hot and oaky.

Final Thoughts: At roughly $250 — more on the secondary market — Cowboy Bourbon is an occasion bottle, not a Tuesday pour, and I’ll be honest that the price puts it out of “recommend to everyone” territory. What it delivers is the fullest expression of what Garrison and the Texas climate can do: all the dense molasses, dark chocolate, and char-forward intensity the distillery is known for, but with enough barrel-selection discipline to stay balanced instead of turning into an oak toothpick. It’s a landmark bottle in my personal bourbon journey and a genuine statement that Texas bourbon belongs in the ultra-premium conversation. Whether it’s worth $250 to you depends on what an experience like this is worth — but on flavor alone, it earns its place.

If You Liked This, Try…

• Garrison Brothers Single Barrel Cask Strength (Mac’s on 2nd) — The same distillery and mashbill at a higher proof and a fraction of the price. A great way to taste the Garrison house character without the flagship premium. Start here if Cowboy Bourbon is out of reach.
• Old Carter American Whiskey Batch 6 — A different path to a similarly dense, dark, syrupy bourbon: 13-year MGP at 134.6 proof rather than young Texas distillate. Worth comparing to see how age and climate each get you to that rich, chewy place.
