Eight ingredients transform bourbon into a timeless cocktail masterpiece with perfect balance.

The bourbon is the foundation—Buffalo Trace or Woodford Reserve deliver optimal quality for this classic cocktail. Avoid flavored whiskeys as they compromise the drink’s integrity. Simple syrup should be made with equal parts sugar and water (heated for dissolution) or purchased from specialty liquor stores that carry Fee Brothers or similar premium brands. Angostura bitters are non-negotiable for authentic flavor.

No simple syrup? Dissolve one teaspoon sugar in one teaspoon warm water—works in a pinch. For bitters, Reagan’s Orange Bitters No. 6 can substitute for both Angostura and orange bitters. The garnish is flexible: a lemon twist works instead of orange, and brandied cherries replace Luxardo. Ice quality matters—use filtered water for clear, slow-melting cubes.

Simple syrup keeps in the fridge for 2-3 weeks. Bitters last years unopened, 6-12 months after opening. Bourbon is shelf-stable indefinitely if unopened. Once opened, it stays good for 1-2 years, though flavor may subtly change over time.

Step-by-Step Instructions for Classic Old Fashioned

Master the timeless technique that defines this enduring cocktail tradition.

Step 1: Muddle and Macerate the Base Components

Begin by placing the Luxardo cherry in the bottom of a rocks glass. Add the 0.5 oz simple syrup followed by both the 2 dashes Angostura bitters and 1 dash orange bitters.

Gently muddle these ingredients together, pressing just enough to release the cherry’s essence without pulverizing it. The goal is to integrate the flavors while maintaining some texture. This maceration process allows the bitters and syrup to infuse with the cherry’s rich, fruity notes.

Step 2: Build the Foundation with Bourbon

Pour the 4 oz bourbon whiskey over the muddled mixture in the glass. I recommend using a high-quality bourbon with a proof between 80-100 for optimal balance—this strength allows the whiskey to stand up to the other bold flavors without overpowering them.

Add the 2 ice cubes to the glass. The ice should be large and clear if possible, as this melts more slowly, preventing over-dilution. Give the mixture a gentle stir to begin the chilling process and marry the ingredients.

Step 3: Express and Garnish with Citrus

Take the orange peel and hold it over the glass, skin-side down. Squeeze it firmly between your fingers to express the oils onto the surface of the drink. This step releases the citrus’s aromatic compounds, adding a bright, fresh dimension to the cocktail.

After expressing, run the peel around the rim of the glass to further infuse the aroma, then drop it into the drink as garnish. The expressed oils will float on the surface, creating an enticing visual and olfactory experience.

Step 4: Dilute and Refine to Perfection

Stir the cocktail gently but thoroughly for about 20-30 seconds. This action chills the drink while gradually diluting it to the ideal strength. The goal is to achieve a smooth, well-balanced sip without over-diluting the flavors.

If you prefer a slightly lighter touch, add the 0.25 oz cold water at this stage. This optional step can soften the drink’s intensity, particularly useful if your bourbon is on the higher proof side. Stir for another 10 seconds to incorporate fully.

Serve immediately, ensuring the ice is still intact and the drink maintains its proper temperature. The final presentation should showcase the rich amber hue of the bourbon with the orange peel and cherry adding visual contrast and depth.

Regional Styles of classic old fashioned recipe with simple syrup

🍹 New York Style

The New York Style Old Fashioned stays true to the cocktail’s 19th-century roots, often using rye whiskey for a spicier kick. This version typically includes a sugar cube muddled with bitters and a splash of water, topped with a twist of orange peel for brightness. The city’s historic bars, like the Pegu Club, helped popularize this no-frills approach, emphasizing balance and simplicity. Served neat or on the rocks, it’s a nod to the drink’s origins in the Big Apple’s early cocktail scene.

🍸 Wisconsin Style

In Wisconsin, the Old Fashioned takes a sweeter turn, often made with brandy instead of whiskey—a nod to the state’s German heritage. The drink is built with simple syrup and muddled orange slices and cherries, then topped with a splash of soda or lemon-lime mixer, called a “pressed” Old Fashioned. This style is a staple at supper clubs and taverns, reflecting the region’s love for approachable, fruit-forward twists on classics.

🥃 Kentucky Style

Kentucky’s version leans heavily on bourbon, the state’s signature spirit. Here, the Old Fashioned is often made with simple syrup for a smoother sweetness, paired with Angostura bitters and a luxardo cherry garnish. The drink is typically served over a large ice cube to slowly dilute the bold flavors. This style celebrates Kentucky’s distilling tradition, offering a richer, more robust take on the cocktail.

🍊 Southern Style

Down South, the Old Fashioned sometimes gets a citrusy upgrade with peach bitters or a muddled peach slice, alongside the classic simple syrup. Bourbon or rye is used, but the addition of seasonal fruit—like blackberries or strawberries—gives it a refreshing, regional flair. This version is popular in states like Georgia and Tennessee, where sweet and boozy flavors shine in warm-weather sipping.
