Best Bourbon For An Old Fashioned

The best bourbon for an Old Fashioned has enough strength, spice and oak character to remain noticeable after sugar, bitters and ice are added. For most drinks, bourbon bottled between 45% and 55% ABV works best. Lower-strength bottles can still work, but delicate flavours are more likely to disappear as the cocktail dilutes.

A good choice does not need to be expensive. Reliable cocktail bourbons usually combine caramel and vanilla from new oak with enough rye spice or alcohol strength to keep the finished drink balanced. Our Bourbon whiskey range provides a useful starting point for comparing bottles by strength, producer and style.

What Makes a Bourbon Good for an Old Fashioned?

A bourbon works well in an Old Fashioned when it can balance sweetness, aromatic bitters and dilution without becoming thin or overly sugary. Strength matters, but the grain recipe, oak influence and maturity of the whiskey also affect the final result.

The most useful characteristics are:

• 45–55% ABV: enough alcohol and flavour concentration to withstand dilution.
• Clear oak character: vanilla, caramel, toasted wood and baking spice complement sugar and bitters.
• A defined secondary grain: rye adds spice, while wheat creates a softer and sweeter drink.
• Reasonable availability: an everyday cocktail bottle should be replaceable without searching for an allocated release.
• Sensible price: expensive or highly limited bourbon is rarely necessary for a mixed drink.

Federal American whiskey standards require bourbon to be produced from a mash containing at least 51% corn and matured in new charred oak containers. The official US standards of identity for whisky also define production-strength and maturation requirements. These rules help explain bourbon’s characteristic base of corn sweetness, vanilla and oak.

What Proof Bourbon Makes the Best Old Fashioned?

The best proof for an Old Fashioned is usually between 90 and 110 proof, equivalent to 45–55% ABV. This range gives the bourbon enough backbone to remain expressive after the ice begins to melt, while avoiding the excessive heat that some cask-strength whiskeys can bring to a simple three-ingredient drink.

Bourbon at 40% ABV can make a pleasant Old Fashioned, particularly when the drink is served immediately over a large cube. However, it requires careful control of the sugar and dilution. Too much syrup or prolonged stirring can quickly obscure the whiskey.

Bottles around 50% ABV are more forgiving. They retain their oak, caramel and spice as the drink opens in the glass. One thing we regularly see with our customers is that a bourbon enjoyed neat at 40% ABV may feel noticeably quieter once bitters, sugar and melting ice are introduced.

Best Bourbons for an Old Fashioned

Wild Turkey 101: Best All-Round Choice

Wild Turkey 101 is one of the most dependable bourbons for an Old Fashioned because its 50.5% ABV, rye-led spice and mature oak character remain clear after dilution. It produces a bold but balanced drink with notes of caramel, vanilla, pepper, cinnamon and toasted oak.

The higher bottling strength means it can support a full measure of bitters and a slightly richer syrup without becoming washed out. It is particularly suitable for drinkers who want a robust cocktail rather than a soft, dessert-like version.

• ABV: 50.5%
• Style: spicy, caramel-rich and oak-led
• Best for: a full-flavoured, traditional-style Old Fashioned
• Typical UK position: accessible mid-range cocktail bourbon

The Wild Turkey distillery guide provides further context on the producer and its characteristically high-strength house style.

Old Forester 100 Proof: Best for Spice and Structure

Old Forester 100 Proof suits an Old Fashioned when you want firm spice, dark fruit and a clear oak backbone. At 50% ABV, it has enough structure to handle dilution while retaining flavours associated with brown sugar, orange peel, cinnamon and toasted wood.

Its profile works particularly well with aromatic bitters and a fresh orange garnish. It is less soft than a typical wheated bourbon, making it a better choice for drinkers who prefer definition and dryness in the finish.

• ABV: 50%
• Style: structured, spicy and fruit-led
• Best for: a drier cocktail with a pronounced bitters character
• Typical UK position: mid-range, depending on availability

Buffalo Trace: Best for a Softer Old Fashioned

Buffalo Trace is a good choice for a rounded and approachable Old Fashioned built around vanilla, caramel and gentle spice. Its 40% ABV makes it less forceful than the higher-proof options, so it benefits from restrained sugar and careful stirring.

The relatively soft profile makes it useful for drinkers who find higher-strength bourbon too hot. Use a small amount of syrup and a large ice cube to prevent excessive dilution.

• ABV: 40%
• Style: soft, sweet and vanilla-led
• Best for: an approachable, less alcoholic Old Fashioned
• Typical UK position: entry to mid-range, with availability varying

Elijah Craig Small Batch: Best for Oak and Baking Spice

Elijah Craig Small Batch makes a richer Old Fashioned with pronounced oak, caramel and baking spice. Commonly bottled at 47% ABV, it sits comfortably within the ideal strength range and retains good definition as the ice melts.

It works well with aromatic bitters and demerara syrup, although the sugar should remain controlled. The mature oak profile can become heavy if the drink is made too sweet.

• ABV: commonly 47%
• Style: oak-led, nutty and warmly spiced
• Best for: a richer cocktail with a longer finish
• Typical UK position: mid-range

Maker’s Mark: Best Wheated Bourbon Option

Maker’s Mark produces a softer and sweeter Old Fashioned because wheat replaces rye as the main secondary grain in its mash bill. The result usually emphasises caramel, vanilla and gentle baking spice rather than peppery rye notes.

At 45% ABV, it has enough strength for a balanced cocktail but remains approachable. It suits drinkers who want less spice, although using too much syrup can make the finished drink overly sweet.

• ABV: 45%
• Style: soft, rounded and caramel-led
• Best for: drinkers who prefer sweetness over rye spice
• Typical UK position: accessible mid-range

High-Rye vs Wheated Bourbon for an Old Fashioned

High-rye bourbon creates a spicier and more structured Old Fashioned, while wheated bourbon produces a softer, sweeter cocktail. Neither style is automatically better. The right choice depends on whether you want peppery definition or a rounded caramel-led drink.

How to Make a Bourbon Old Fashioned

A balanced bourbon Old Fashioned uses approximately 60ml bourbon, a small measure of sugar syrup and two or three dashes of bitters. Stirring the drink with ice provides controlled dilution, while expressing an orange peel over the surface adds aroma without adding juice.

1. Add 5ml of simple or demerara syrup to a mixing glass.
2. Add two or three dashes of aromatic bitters.
3. Pour in 60ml bourbon.
4. Fill the mixing glass with solid, fresh ice.
5. Stir approximately 20–25 times.
6. Taste and stir a little longer only if the alcohol feels too sharp.
7. Strain over one large ice cube in a short tumbler.
8. Express an orange peel over the drink and place it in the glass.

A higher-proof bourbon may need slightly more stirring. A 40% ABV bourbon normally needs less dilution and no more than 5ml of syrup. Our guide to drinking bourbon neat, with water or in cocktails explains how strength and dilution affect the whiskey in different serving formats.

When to Use an Expensive Bourbon

Premium bourbon can be used in an Old Fashioned, but additional cost does not guarantee a better cocktail. Long maturation, subtle cask finishes and delicate aromas may be difficult to detect once sugar and bitters are added.

Using a more expensive bottle makes sense when:

• the bourbon is already open and you understand its flavour profile;
• its higher proof or distinctive cask character materially changes the drink;
• you reduce the sugar and bitters to keep the whiskey central;
• you are comparing the same recipe across several bourbons.

Avoid using an allocated, historic or difficult-to-replace bottle simply because it is considered prestigious. A reliable 45–50.5% ABV bourbon will usually make a more balanced everyday cocktail at a much more sensible cost.

Bourbon vs Rye for an Old Fashioned

Bourbon makes a sweeter and rounder Old Fashioned, while rye whiskey produces a drier, spicier and more herbal drink. Rye was historically common in early American whiskey cocktails, but bourbon has become the more approachable modern choice. The preparation method and basic proportions remain the same.

Frequently Asked Questions

What is the best bourbon for an Old Fashioned?

Wild Turkey 101 is one of the strongest all-round choices because its 50.5% ABV, rye spice and oak character remain noticeable after sugar, bitters and ice are added. Old Forester 100 Proof is a good alternative for a structured drink, while Maker’s Mark suits those who prefer a softer style.

Is Buffalo Trace good for an Old Fashioned?

Buffalo Trace makes a soft, approachable Old Fashioned with vanilla, caramel and gentle spice. Its 40% ABV means it can become diluted more quickly than higher-proof bourbon. Use no more than a small spoon of syrup, stir briefly and serve over a large ice cube.

What is the cheapest bourbon that still makes a good Old Fashioned?

Wild Turkey 101 is often one of the best-value choices available to UK buyers because its 50.5% ABV survives dilution particularly well. Evan Williams Bottled-in-Bond can also perform strongly when available. Price matters less than choosing a bottle with sufficient strength and a clearly defined flavour profile.

Can I use 40% ABV bourbon in an Old Fashioned?

Yes. Bourbon bottled at 40% ABV can make a balanced Old Fashioned, but the recipe needs less sugar and careful dilution. Use approximately 5ml syrup, stir briefly and serve over a large cube. A higher-strength bourbon is generally more forgiving because it retains more character as the ice melts.

Should I muddle the orange in an Old Fashioned?

Muddling orange flesh adds juice, bitterness and extra sweetness, which can obscure the bourbon. A cleaner approach is to express a strip of orange peel over the finished drink. This releases aromatic oils across the surface without changing the cocktail’s underlying balance.

Choosing Your Bourbon

The best bourbon for an Old Fashioned is usually bottled between 45% and 55% ABV, has enough oak and spice to withstand dilution, and is affordable enough to use regularly. Wild Turkey 101 and Old Forester 100 Proof suit bold, structured drinks. Buffalo Trace and Maker’s Mark produce softer versions, while Elijah Craig Small Batch adds more mature oak character.

Focus on strength and flavour structure rather than prestige. To compare these bottles with other distilleries, styles and releases, explore the wider American whiskey collection.
