How to Make a Big Batch of Old Fashioned Cocktails

Step 1: Mix the alcohol

Measure the bourbon into a large mixing glass or measuring cup. Add the orange bitters and whisk briefly to combine. Transfer the mixture to a large pitcher, clip-top carafe, or bottle for easy serving.

Step 2: Add the syrup

Stir in the brown sugar simple syrup, or seal the carafe and give it a gentle shake until the syrup is fully incorporated.

Step 3: Chill

Place the container in the refrigerator or freezer until the batch is very cold. Keep the mixture ice-free until serving so it doesn’t dilute.

Step 4: Serve

For each cocktail, pour 2 to 2.5 ounces of the premixed Old Fashioned into a lowball glass over one large ice cube or several small cubes.

Step 5: Garnish

Finish with a cinnamon stick or a few cherries—amaros or luxardo cherries add depth. Alternatively, offer a garnish station with orange slices, cinnamon sticks, star anise, and cherries so guests can customize their drinks.

FAQs

How do you make brown sugar simple syrup?

Combine 1 cup packed brown sugar and 1 cup water in a saucepan. Heat over medium until it simmers, add a cinnamon stick if you like, then reduce heat and simmer gently for about five minutes. Remove from heat, cool, and store in an airtight container in the refrigerator for up to a week.

How far in advance can I make this batch?

You can prepare the cocktail one or two days ahead and keep it refrigerated. Do not add ice until serving to avoid unwanted dilution.

What’s the secret to a great Old Fashioned?

Balance. The right proportion of bitters to bourbon and sweetener is key—bitters provide aroma and structure, while the sugar smooths the edges without masking the whiskey.

Serving Suggestions + Variations

  • Serve this cocktail as a Thanksgiving nightcap alongside pie—its whiskey-forward profile pairs beautifully with pecan or maple desserts.
  • If you don’t have brown sugar syrup, substitute regular simple syrup or maple syrup for a slightly different sweetness and aroma.
  • For a playful pairing, offer donut holes or small dessert bites alongside the drinks.
  • For an extra-sweet rim, dip the glass in syrup and then in coarse brown sugar.
  • Pair with dark chocolate orange candies or roasted nuts for an elegant seasonal snack pairing.
