Garrison Brothers' 2026 Cowboy Bourbon Is Here — and It's Bringing 141 Proof of Texas Heat
Every September, the Hill Country outside of Austin, Texas, transforms into something of a bourbon pilgrimage destination. Men drive in from Houston and Dallas, some from as far as the coasts, all converging on a small town called Hye with a single goal: get their hands on a bottle of Garrison Brothers Cowboy Bourbon before it sells out. This year is no different. Garrison Brothers has announced that its 2026 Cowboy Bourbon will be released at its distillery in Hye, Texas, on Saturday, September 12, 2026. The faithful will need to show up early — very early. The first 1,000 bottles of the cask-strength, uncut, and unfiltered Texas Straight Bourbon Whiskey will go on sale at 8 a.m. that day.
This is not a whiskey for the timid. It never has been. At 141 proof (70.5% ABV), the 2026 Cowboy Bourbon reaches "Hazmat" territory and yet, somehow, doesn't reach the proof level of 2025's Cowboy release, which was bottled at 146.4 proof. What makes that fact remarkable is not the slight dip in proof — it's that Garrison Brothers has been operating in this stratospheric range so consistently that a 141-proof whiskey can feel almost restrained by comparison.
The Distillery Behind the Legend
To fully understand what Cowboy Bourbon represents, you have to understand where it comes from — and why Texas, of all places, produces bourbon that can hit these extremes. Garrison Brothers is located in Hye, Texas, which is about an hour outside of Austin. It was founded in 2006 and released its first bourbon four years later, making it the oldest legal whiskey distillery in the state. That pioneering position matters. When Dan Garrison set out to make bourbon in the Texas Hill Country, plenty of people in Kentucky were paying little attention. Two decades later, they are.
The distillery is known for making a very assertive style of bourbon which is very different from what you will find coming out of Kentucky. The distillery makes one thing and one thing only — bourbon, and specifically wheated bourbon that uses wheat as the secondary flavoring grain instead of rye, the same style that brands like Maker's Mark and Pappy Van Winkle produce. That wheated mash bill is foundational to understanding Cowboy Bourbon's flavor profile. Wheat, as a grain, contributes softness and sweetness — but in Texas, "soft" is a relative term. The climate does most of the heavy lifting when it comes to shaping the barrel's personality.
The Texas Hill Country is a brutal aging environment. Summer temperatures regularly crack triple digits, and the dramatic swings between hot days and cooler nights force the whiskey deep into and out of the wood with relentless aggression. Garrison Brothers selects standout barrels as they mature under the intense Texas climate, setting favored casks aside for further aging before marrying them for the final Cowboy Bourbon release. This process — identifying exceptional barrels early and continuing to nurse them — is what separates Cowboy Bourbon from a simple dump-and-bottle operation. These are already the best barrels in the rickhouse, and then they're given more time.
What Makes the 2026 Edition Different
Eight Years Under the Texas Sun
The 2026 edition marks the 12th release of Cowboy Bourbon. That twelve-year run represents a remarkable arc of consistency in a category where annual releases live and die by the quality of a single season's barrels. Garrison Brothers produced 16,000 bottles of the 2026 release, which was aged for at least eight years. Master Distiller Donnis Todd hand-selected the barrels used for the limited-edition bourbon, which was bottled at cask strength without being cut or filtered. Eight years of aging in a Texas climate is not the same as eight years in a Kentucky warehouse. The extreme seasonal temperature variation in the Hill Country accelerates extraction, deepens char interaction, and concentrates the spirit in ways that would take considerably longer in a more temperate environment.
Cowboy Bourbon showcases selected barrels at their natural strength, bottled uncut and unfiltered to retain maximum texture, concentration and barrel character. No water. No filtration. Nothing between the barrel and the bottle except Todd's trained palate. Unlike the distillery's proofed-down expressions, Cowboy Bourbon is bottled at cask strength without adding water to reduce its proof. For enthusiasts who prize transparency in their whiskey — knowing that what's in the glass is exactly what came out of the wood — this approach represents the gold standard.
The Proof History: A Running Record of Extremes
One of the most interesting ways to contextualize the 2026 Cowboy Bourbon is by looking at where it sits in the series' proof history. Compare that to last year's release which came in at a truly hefty 146.4 proof, the 2024 release bottled at 140.2 proof, and the 2023 release at 140.9 proof. What emerges from that data is a picture of a whiskey that consistently hovers around the hazmat threshold — defined as any spirit over 140 proof — year after year. This isn't a marketing stunt or a one-time novelty. Garrison Brothers has built a program around a whiskey that legitimately reaches these levels because of how its barrels age, not because someone decided extreme proof was fashionable.
The hazmat whiskey trend shows no signs of slowing down — on the contrary, it seems that even more of these high-proof flamethrowers are being released these days. But it's worth separating the imitators from the originators. Garrison Brothers has been producing Cowboy Bourbon since 2013, well before "hazmat" became a word that sold bottles. First released in 2013, Cowboy Bourbon helped put Garrison Brothers and Texas on the national bourbon map. That's the distinction: Cowboy Bourbon's proof is a byproduct of an authentic production philosophy, not a calculated positioning exercise.
Inside the Bottle: Tasting Notes and Flavor Profile
At 141 proof, the first challenge for any drinker is simply getting past the heat. The reward, for those who do, is considerable. The 2026 expression opens with "distinctive aromas of burnt wood and gunsmoke" before maturing into a complex profile of "dried stone fruit, toasted marshmallows, and caramelized sugar," according to the Texas whiskey brand. That opening salvo of burnt wood and gunsmoke is arresting — it's not for everyone, and Garrison Brothers isn't pretending otherwise. This is a whiskey that announces itself without apology.
The distillery describes the bourbon's profile as opening with notes of burnt wood and gun smoke before moving into dried stone fruit and caramelized sugar. Todd said the whiskey develops additional layers of dried fruit and toasted marshmallow as it opens up. That evolution — from aggressive and smoky at first sniff to something more layered and complex with time in the glass — is characteristic of the best high-proof Texas bourbons. A few drops of water or a single ice cube can pull entirely different dimensions from the spirit, and seasoned drinkers often rotate between neat, slightly diluted, and on the rocks to explore the range.
Master Distiller Donnis Todd has articulated that complexity plainly. "It comes on strong at first, but the depth of flavor quickly draws you in," Todd said. That's the promise of Cowboy Bourbon in a sentence — it tests your patience, then rewards it. According to Garrison Brothers, the result is a multi-layered, memorable whiskey loaded with flavors like burnt wood, gun smoke, dried stone fruit, and caramelized sugar.
What the Previous Vintage Tells Us
The 2025 Cowboy Bourbon — the highest-proof release in the series' history at 146.4 proof — provides useful color for what the 2026 vintage might deliver with slightly less fire. Independent reviews of the 2025 edition described notes of caramel, maple, oak, dried grain, leather, and cinnamon on the palate, with a warm, extended finish. One reviewer noted a deep, rich mahogany color that stood out from other bourbons. The 2026 edition, aged a full two years longer than the 2025 release, should theoretically carry even deeper barrel influence — more toasted wood character, more dried fruit concentration, and a finish that lingers well after the glass is empty.
The distillery's 2025 Cowboy Bourbon earned a Platinum medal at the 2026 ASCOT Awards and a Double Gold medal at the 2026 SIP Awards. Those are not minor accolades in the competitive spirits world, and they add real credibility to Garrison Brothers' run of form heading into the 2026 release. The pressure to deliver is high, but the track record suggests Todd and his team know exactly what they're doing with these barrels.
How to Get Your Hands on a Bottle
The Hye Launch Event — September 12
The most coveted path to a bottle of the 2026 Cowboy Bourbon is showing up in person on release day. This is a family and dog-friendly event where guests can enjoy coffee, breakfast, and lunch at The Whiskey Shack while they wait. There will also be live music, bottle signings, bourbon tasting, distillery tours, and specialty cocktails available. For those willing to make a weekend of it, the Hill Country itself is worth the trip — rolling limestone hills, cypress-lined rivers, and more than a few other craft distilleries and wineries in the surrounding towns of Fredericksburg and Johnson City. But make no mistake: the line starts early, and the serious buyers will be positioned well before that 8 a.m. bell.
Only the first 1,000 bottles will be available at the distillery on September 12. That sounds like a substantial number until you consider the size of the crowd that typically materializes for these events and the reality that many attendees are buying for themselves, their friends, and the secondary market simultaneously. The highly sought-after, hand-crafted spirit will ride again when it launches at the distillery's Hye, Texas location that morning, where the first 1,000 bottles will be available to early-bird buyers. If history is any guide, that allocation will be gone well before noon.
The Online Allocation — September 18
For those who can't make the trek to Hye, there is a brief window of digital opportunity. Garrison Brothers will offer 279 bottles of the 2026 Cowboy Bourbon through its e-commerce store beginning September 18, with online purchases limited to one bottle per order and engraving available. Two hundred seventy-nine bottles for the entire country is, in any practical sense, almost nothing. These will move in minutes. Anyone hoping to secure one should have their account set up, their payment information ready, and their browser pointed at the Garrison Brothers website well before the store goes live.
Nationwide Retail — October 1
After the initial event, the 2026 edition of Cowboy Bourbon will be available at select bars, restaurants, and whiskey retailers throughout the US beginning October 1, 2026, for the suggested retail price of $249.99 for a 750ml bottle. That price point places Cowboy Bourbon squarely in premium allocated-whiskey territory — comparable to what enthusiasts pay for sought-after annual releases from Buffalo Trace's Antique Collection or the higher-end single barrel programs from Kentucky's major distilleries. Whether that price is justified is, at this point, not seriously debated among those who have actually opened a previous year's bottle.
The retail distribution is described as selective — not every liquor store in every state will receive an allocation. Presented with a 2026 Cowboy Bourbon medallion and substantial wooden display case, this release is designed for serious Garrison Brothers collectors, rare-bourbon enthusiasts, milestone gifting and premium whiskey displays. The packaging itself reinforces the collectible nature of the release. These bottles are not made to live behind the bar rail where they'll be gone in a week. They're made to be displayed, poured carefully, and savored on occasions that warrant a $250 bottle of whiskey.
The Bigger Picture: Texas Bourbon's Moment
It would be easy to dismiss the Cowboy Bourbon phenomenon as regionalist hype — Texas boosterism dressed up in wax-sealed bottles and cowboy mythology. That reading misses the point entirely. What Garrison Brothers has done over twelve editions of Cowboy Bourbon is document, in proof and flavor, the reality of what extreme climate aging does to whiskey. The distillery is known for making a very assertive style of bourbon which is very different from what you will find coming out of Kentucky. That assertiveness is a feature, not a flaw — it's the direct expression of a specific place, a specific climate, and a specific philosophy about what bourbon can be outside the traditional geographic and stylistic boundaries.
The proof data alone tells a compelling story. Every year since 2013, Garrison Brothers has dumped barrels that were already aging in one of the most inhospitable climates on the continent, and what's come out has consistently hit hazmat levels. And sometimes that bourbon reaches hazmat levels, which is often the case with the annual Cowboy Bourbon release. The consistency of that outcome is not an accident of luck — it's the logical result of extreme heat, limestone-filtered Texas water, a wheated mash bill, and the patient attention of a master distiller who has spent years learning how Hill Country rickhouses behave.
The broader American bourbon market has been watching Texas with increasing respect. States from Wyoming to New York have developed serious craft distilling programs, but Texas — driven largely by Garrison Brothers' early investment and the credibility that Cowboy Bourbon has generated — has staked out a uniquely identifiable regional identity in the whiskey world. The argument that authentic bourbon can only come from Kentucky grows harder to make every September when Cowboy Bourbon drops and immediately sells out.
A Word on Drinking It
Practical advice matters when the subject is a 141-proof whiskey. Anyone pouring the 2026 Cowboy Bourbon neat for the first time without experience with high-proof spirits is in for a genuinely challenging experience. The ethanol presence at this strength is significant — it will dominate an unprepared palate and wash out the nuances that make the bourbon interesting. The right approach is patience: pour a modest amount, let it open for five to ten minutes in the glass, take a small sip and let it settle, and then decide how much water, if any, works for you.
The 2026 edition reaches 141.0 proof, creating a dense, full-bodied sipping experience built for seasoned high-proof bourbon enthusiasts. Garrison Brothers isn't hiding from that descriptor. This is a specialist's whiskey in the most literal sense — it rewards knowledge, patience, and the willingness to engage with something that demands more than casual attention. For collectors who track their bottles by vintage and proof, the 2026 edition is already a data point in a twelve-year series worth following. For first-timers, it's an education in what American whiskey is capable of when geography, climate, and craft converge without compromise.
September 12 in Hye will come and go fast. The bottles will follow shortly after. And when the 2027 edition is announced next summer, the faithful will line up again — because that's what happens when a distillery earns the kind of loyalty that Garrison Brothers has built one searing, unfiltered pour at a time.
