Demerara syrup is a simple syrup made with demerara sugar, a less refined sugar with a deeper, richer flavor than white sugar. It’s the golden child of cocktail syrups, especially when it comes to the Old Fashioned.  

Why is it so good in an Old Fashioned?

• Complex flavor profile: Demerara sugar retains more of the molasses from the sugarcane, giving the syrup a caramel-like sweetness and a touch of bitterness. These flavors complement the whiskey’s character beautifully.
• Rich mouthfeel: The syrup is typically made with a higher sugar-to-water ratio, resulting in a thicker, more luxurious texture that coats the palate nicely.  
• Enhanced depth: It adds depth and complexity to the cocktail without overpowering the other ingredients.  

Using Demerara syrup, you elevate your Old Fashioned from a classic to an exceptional drink. It’s a small change that makes a big difference.

Homemade Demerara Syrup

I always use Jack Rudy Cocktail Demerara Syrup because it’s delicious and convenient to have on hand. But, you can always make your own! All you need is 2 cups of Demerara sugar and 1 cup of hot water.

Just combine the Demerara sugar and hot water in a medium saucepan, stir continuously over medium-low heat until the sugar is completely dissolved. Avoid boiling the syrup. Then let the syrup cool completely before transferring it to a clean glass jar or bottle. Store in the refrigerator.

Old Fashioned Cocktail

Add 1/2 ounce Demerara syrup to 2 ounces of bourbon or rye and 2 dashes of Angostura bitters for a simple but exceptional Old Fashioned. Garnish with orange peel, and a couple of cherries, and enjoy!
