Cask strength bourbon is my favourite way to drink American whiskey. No dilution, no chill filtration — just pure barrel-proof spirit bottled exactly as the distiller found it. The flavours are more concentrated, the texture is richer, and you get to control the experience by adding your own water to find the sweet spot. I have tasted hundreds of cask strength releases, and these ten represent the very best available right now.
1. A. Smith Bowman Cask Strength Bourbon Batch #2
Rating: 9.5/10 | Price: $75 | ABV: 69.45%
Virginia bourbon at nearly 70% ABV, and yet it drinks with remarkable elegance. Rich caramel, dark cherry, leather, and a finish that stretches for minutes. Bowman has quietly become one of America's finest distilleries, and this cask strength release is the proof. When I first tasted this, I genuinely struggled to believe the price — it competes with bottles at three times the cost.

2. Garrison Brothers Cowboy Bourbon 2023
Rating: 9.0/10 | Price: $250 | ABV: 68.2%
Texas heat pushes bourbon to its limits, and Cowboy is the result — huge, intense, and absolutely magnificent. Dark toffee, leather, tobacco, and a viscosity that coats your mouth like honey. It is expensive, but this is a once-a-year release that sells out immediately for a reason. Add a teaspoon of water and it opens like a flower. One of the most impressive bourbons I have ever tasted.

3. Woodinville Moscatel Finished Straight Bourbon
Rating: 8.5/10 | Price: $55 | ABV: 45%
Washington State bourbon finished in moscatel wine casks for something genuinely unique. Grape sweetness, floral notes, and vanilla oak — it is a bourbon that surprises everyone who tries it. The wine cask influence makes it more versatile than most cask strength expressions. I used this for cocktails that needed something different, and it never disappointed.

4. Remus Repeal Reserve VI Straight Bourbon
Rating: 9.0/10 | Price: $95 | ABV: 50%
A medley of carefully selected bourbons blended to create something greater than its parts. The sixth release is the best yet — layered dark fruit, oak spice, and a muscular body that rewards slow sipping. At 100 proof it has enough power to stand up to ice without losing its character. This is the bottle I pour when I want to demonstrate that craft bourbon can compete with the established names.

5. Booker's Bourbon Lumberyard Batch
Rating: 9.0/10 | Price: $90 | ABV: 62.95%
Booker Noe's legacy in a glass. Uncut, unfiltered, and unapologetically bold — this is bourbon with its sleeves rolled up. Vanilla, peanut brittle, charred oak, and a warmth that spreads through your whole chest. Every batch is slightly different, and the Lumberyard is a particularly good one. Add water slowly and watch the flavours shift. This is how bourbon was meant to be experienced.

6. Michter's 20-Year-Old Kentucky Straight Bourbon
Rating: 9.5/10 | Price: $900 | ABV: 57.1%
Twenty years in a Kentucky rickhouse has produced something extraordinary. Dark cherry, leather, tobacco, ancient oak, and a finish that lasts for what feels like five minutes. It is one of the most complex American whiskeys ever made. The price is staggering, but so is the liquid. If you ever get the opportunity to taste this, do not hesitate for a second.

7. Wyoming Whiskey 1872 Straight Bourbon
Rating: 8.5/10 | Price: $45 | ABV: 48%
Clean mountain water and Wyoming grain produce a bourbon with a distinctive character — less sweet than Kentucky, more mineral, with a crisp finish that sets it apart. At forty-five dollars it is the best value on this list by a distance. The proof is modest, but the flavour is anything but. A bottle I recommend to everyone who thinks bourbon can only come from one state.

8. Bhakta 2013 Bourbon
Rating: 8.5/10 | Price: $100 | ABV: 52.5%
Bhakta finishes their bourbon in Armagnac casks, and the result is unlike anything else in the category. French oak influence brings dried fruit, grape, and a European sophistication that transforms the bourbon base. It is creative, well-executed, and genuinely fascinating to drink. This is the bottle I pour when someone tells me bourbon is boring — it changes minds instantly.

9. Rabbit Hole Raceking Kentucky Straight Bourbon
Rating: 8.0/10 | Price: $60 | ABV: 50%
A Kentucky Straight Bourbon with a high-wheat mash bill that produces something soft, sweet, and refined. Toffee, butterscotch, and gentle spice — it drinks much more smoothly than its 100 proof suggests. Rabbit Hole has carved out a premium position in the craft bourbon market, and Raceking is their most crowd-pleasing expression. It was a reliable crowd-pleaser behind the bar.

10. Van Winkle Special Reserve 12 Year Old
Rating: 9.0/10 | Price: $80 | ABV: 45.2%
The Van Winkle name carries extraordinary weight in bourbon circles, and the 12-year-old Special Reserve deserves every ounce of its reputation. Wheated bourbon aged with patience — caramel, cherry, toffee, and a silky smoothness that makes it almost dangerously easy to drink. Finding a bottle at retail price is the challenge, but if you do, it is one of the most satisfying bourbons you will ever taste.
