Classic bourbon takes center stage with just a few refined companions for this timeless cocktail.

The bourbon is everything here. Small-batch labels like Woodford Reserve or Buffalo Trace deliver the depth this drink deserves. Avoid the bottom-shelf stuff—its harsh notes will fight the simple syrup. For the bitters, Angostura is non-negotiable; its complex spice profile defines the Old Fashioned. Most liquor stores carry it, but Total Wine has the best selection if you’re stocking up.

No simple syrup on hand? Dissolve 1 teaspoon sugar in 1 teaspoon warm water for a single serving. Short on Angostura? Reyka or Fee Brothers work in a pinch, though the flavor profile shifts slightly. Luxardo cherries are the gold standard for garnish (Whole Foods carries them), but brandied cherries from Trader Joe’s are a solid backup. The orange peel must be fresh—bottled citrus oils taste artificial.

Simple syrup keeps in the fridge for up to 1 month. Bourbon stays good indefinitely if unopened, but once cracked, finish within 6-12 months for peak flavor. Prep the orange peels right before serving—their oils oxidize quickly.

Step-by-Step Instructions for Old Fashioned With Simple Syrup

This classic method delivers perfectly balanced flavors with minimal effort and maximum elegance.

Step 1: Prepare the Simple Syrup Base

In a small saucepan, combine the 1 cup Granulated Sugar with the 1 cup Water. Stir over medium heat until the sugar fully dissolves and the mixture becomes clear—this should take about 3-4 minutes.

Remove from heat and let it cool to room temperature. The syrup should have a smooth, thin consistency. I always make this first so it’s ready when I need it. Properly cooled syrup prevents dilution of the final drink.

Step 2: Muddle the Orange Peel and Bitters

In a rocks glass, place the 1 piece Orange Peel and add the 2 dash Angostura Bitters. Gently press the peel with a muddler or the back of a spoon to release its oils, being careful not to over-muddle—this prevents bitterness from the pith.

The goal is to extract the aromatic oils without breaking the peel apart. You’ll notice the bitters start to absorb the citrus essence immediately. This step builds the foundation of the drink’s complex aroma.

Step 3: Build the Drink with Bourbon and Simple Syrup

Add the 4 oz Bourbon Whiskey and the 0.5 oz Simple Syrup to the glass. Stir gently with a bar spoon for about 10-15 seconds to combine the ingredients without over-diluting the bourbon.

The simple syrup should blend seamlessly into the bourbon, creating a smooth, slightly sweet base. Taste at this stage to ensure the balance is right—adjusting now is easier than after adding ice.

Step 4: Add Ice and Final Touches

Fill the glass with the 4 pieces Ice Cubes. Large, dense cubes are ideal as they melt slowly, preventing the drink from becoming watery too quickly. Stir once more for 5-10 seconds to chill the mixture evenly.

The ice should glisten as it interacts with the bourbon, creating a visually appealing drink. The proper chill enhances the flavors and provides the signature dilution that mellows the bourbon’s bite.

Step 5: Garnish and Serve

Express the oils from the 1 slice Orange Slice over the drink by giving it a slight twist above the glass, then drop it in. Skewer the 2 whole Luxardo Cherries with the 1 whole Cocktail Pick and place them on the rim or in the glass.

The garnish should be visually striking but functional. The orange slice adds a fresh citrus note, while the cherries provide a touch of luxury. Serve immediately to enjoy the drink at its peak.

Flavor Customization for These Flavors

🔥 Make it Spicier

For a bold kick, add 2 tsp cayenne pepper or a few dashes of hot sauce to your old fashioned recipe with simple syrup. This spicy twist enhances the bourbon’s warmth and balances the sweetness, creating a layered, fiery finish that lingers on the palate. A pinch of black pepper can also add subtle depth without overpowering the drink.

🍯 Add Sweetness

If you prefer a sweeter profile, increase the simple syrup to 1.5 oz or incorporate 1 tsp honey or maple syrup. Honey adds floral notes, while maple syrup introduces a rich, earthy undertone. These adjustments soften the bourbon’s sharpness, making the cocktail smoother and more approachable.

🍋 Tangy Twist

Brighten up your old fashioned with a 0.5 oz splash of lemon or orange juice. The citrus acidity cuts through the sweetness and adds a refreshing zing. For extra complexity, muddle a few orange or lemon peels in the glass before mixing—this releases aromatic oils that elevate the drink’s aroma and taste.

🔥 Extra Smoky

To infuse a smoky essence, use smoked simple syrup or add 1 drop of liquid smoke. Alternatively, char a cinnamon stick or a slice of orange peel over an open flame and use it as a garnish. This imparts a deep, campfire-like flavor that complements the bourbon’s natural oakiness.

🎯 Umami Boost

For a savory depth, stir in 1 tsp soy sauce or a dash of Worcestershire sauce. Sounds unconventional, but the umami richness enhances the bourbon’s caramel and vanilla notes, creating a more complex, well-rounded sip. A sprinkle of smoked salt on the rim can also add a subtle, savory finish.
