Best Single Barrel Bourbon Cocktails to Make at Home

Single barrel bourbon is one of the most discussed and sought after categories in American whiskey — and for good reason. Every bottle comes from one individual barrel, meaning the flavor profile is uniquely its own. No blending, no averaging out, no consistency across batches. What you get is the purest, most direct expression of what that specific barrel developed over years of maturation in a Kentucky warehouse.

Most people treat single barrel bourbon as a neat sipper — and that is absolutely the right instinct. But single barrel bourbon also makes some of the finest cocktails you can build at home, precisely because the depth and complexity of the liquid elevates every drink it touches. Here are the best single barrel bourbon cocktails worth making.

1. The Single Barrel Old Fashioned

The Old Fashioned is the cocktail that single barrel bourbon was born for. Its simplicity is its genius — with only three core components, the quality of the bourbon is the entire point of the drink. There is nowhere to hide and nothing to mask. A single barrel bourbon with genuine depth and character makes an Old Fashioned that a blended bourbon simply cannot match.

What You Need:

• 2oz single barrel bourbon
• 1 sugar cube or half teaspoon of simple syrup
• 2 dashes Angostura bitters
• Orange peel for garnish
• Large ice cube

How to Make It: Place the sugar cube in a rocks glass and saturate with bitters. Add a splash of water and muddle until dissolved. Add the single barrel bourbon and stir gently for 20 seconds. Add a large ice cube, express the orange peel over the glass to release its oils, and drop it in as garnish.

2. The Single Barrel Manhattan

The Manhattan is the cocktail for drinkers who want their bourbon to work harder. Sweet vermouth adds herbal complexity and dried fruit character that pairs beautifully with a bourbon that has genuine depth — and single barrel expressions deliver that depth in a way blended bourbons rarely do.

What You Need:

• 2oz single barrel bourbon
• 1oz sweet vermouth
• 2 dashes Angostura bitters
• Maraschino cherry for garnish

How to Make It: Combine bourbon, vermouth, and bitters in a mixing glass filled with ice. Stir for 30 seconds until well chilled. Strain into a chilled coupe glass. Garnish with a maraschino cherry.

3. The Single Barrel Whiskey Sour

The Whiskey Sour is one of the most universally appealing bourbon cocktails — bright, refreshing, and balanced between sweet and sour in a way that makes it accessible to almost every palate. Using a single barrel bourbon instead of a standard blended expression adds a layer of complexity that takes this classic from simple to genuinely impressive.

What You Need:

• 2oz single barrel bourbon
• 1oz fresh lemon juice
• 0.75oz simple syrup
• 1 egg white (optional but recommended)
• Lemon wheel and cherry for garnish

How to Make It: Combine all ingredients in a shaker without ice and shake hard for 15 seconds to emulsify the egg white. Add ice and shake again for another 15 seconds. Double strain into a rocks glass over fresh ice. Garnish with a lemon wheel and cherry.

4. The Single Barrel Boulevardier

The Boulevardier is the bourbon answer to the Negroni — replacing gin with bourbon and letting the spirit's sweetness and depth balance the bitterness of Campari. It is a cocktail that rewards quality ingredients, and a single barrel bourbon brings exactly the kind of richness and character this drink needs to reach its potential.

What You Need:

• 1.5oz single barrel bourbon
• 1oz Campari
• 1oz sweet vermouth
• Orange peel for garnish

How to Make It: Combine all ingredients in a mixing glass filled with ice. Stir for 30 seconds until well chilled. Strain into a chilled coupe or rocks glass over a large ice cube. Express an orange peel over the glass and use as garnish.

5. The Single Barrel Mint Julep

The Mint Julep is the cocktail most associated with bourbon culture — the official drink of the Kentucky Derby and a symbol of Southern hospitality that has endured for over a century. Made with a single barrel bourbon, it becomes something considerably more elevated than the standard version most people have encountered.

What You Need:

• 2.5oz single barrel bourbon
• 0.75oz simple syrup
• 8 to 10 fresh mint leaves
• Crushed ice
• Fresh mint sprig for garnish

How to Make It: Place mint leaves in the bottom of a julep cup or rocks glass. Add simple syrup and gently press the mint — do not muddle aggressively, just enough to release the oils. Fill the glass with crushed ice. Pour the single barrel bourbon over the ice and stir gently until the outside of the cup frosts. Top with more crushed ice and garnish with a fresh mint sprig.

Best Single Barrel Bourbon for This Cocktail: Blanton's Original Single Barrel — its approachable sweetness and subtle spice make it the ideal julep bourbon, delivering enough complexity to be interesting without fighting the freshness of the mint.

6. The Single Barrel Brown Sugar Lemonade

For warm weather entertaining, the Brown Sugar Lemonade is the single barrel bourbon cocktail that surprises everyone who tries it. It is refreshing, approachable, and complex enough to keep bourbon drinkers genuinely interested across multiple glasses.

What You Need:

• 2oz single barrel bourbon
• 1oz fresh lemon juice
• 0.75oz brown sugar simple syrup
• Splash of sparkling water
• Lemon wheel and fresh thyme for garnish

How to Make It: Combine bourbon, lemon juice, and brown sugar syrup in a shaker with ice. Shake well for 15 seconds. Strain into a tall glass over fresh ice. Top with a splash of sparkling water and stir gently. Garnish with a lemon wheel and a sprig of fresh thyme.
