When it comes to crafting next-level cocktails, one of the most overlooked (yet incredibly powerful) ingredients is oleo saccharum. Latin for "oil sugar," this citrus-infused syrup has been a staple in punch recipes since the 19th century—and for good reason. It’s intensely aromatic, rich, and adds a depth of citrus flavor you simply can't get from juice alone. In this post, we’ll explain what oleo saccharum is, how to make it at home, and how to use it to elevate your cocktails.
What Is Oleo Saccharum?
Oleo saccharum is made by extracting the essential oils from citrus peels using sugar. The sugar draws out the oils through osmosis, creating a sweet, fragrant syrup that captures the zest of citrus without the acidity of the juice.
Unlike squeezing a lemon, which gives you sharp acidity, oleo saccharum delivers pure citrus aroma and flavor—the stuff you smell when you twist a lemon peel over a drink. That’s what makes it magical in cocktails and punches.
Ingredients & Instructions
To make a basic batch, you’ll need peels from 4 to 6 lemons (or any citrus: oranges, grapefruits, limes) and 1 cup granulated sugar. Pro tip: Use organic citrus when possible since you're using the peel, and rinse/scrub well to remove wax or residue.
Peel Your Citrus use a vegetable peeler to remove the outer zest of the fruit—just the colored part, not the bitter white pith. Aim for long, wide strips to maximize surface area. Combine with Sugar place the citrus peels in a bowl and cover them with sugar. Use your hands or a muddler to gently press and mix the sugar into the peels. You don’t need to dissolve the sugar—just coat the peels thoroughly. Wait and Let It Work cover the bowl with plastic wrap and let it sit at room temperature for 4 to 12 hours. Over time, the sugar will draw out the oils, turning into a sticky, fragrant syrup. You can stir it occasionally to help the process along. You’ll know it’s ready when the sugar looks wet and syrupy and the peels look shriveled. Strain and Store strain the syrup into a clean glass jar or bottle. You can add a small splash of lemon juice or warm water to help dissolve any leftover sugar, but don’t dilute it too much. Store your oleo saccharum in the fridge for up to a week (though it’s best fresh).
How to Use Oleo Saccharum in Cocktails
Classic Punches add to rum or whiskey punches for rich, citrusy sweetness. Whiskey Sour Twist use instead of simple syrup for a bright flavor. French 75 mix with gin and sparkling wine for a citrusy upgrade.
Final Thoughts
Oleo saccharum is proof that sometimes the peel is more powerful than the fruit. It's easy to make, wildly aromatic, and a secret ingredient that turns good drinks into unforgettable ones. Whether you're mixing up a batch of punch or experimenting with your own creations, this citrus syrup is your new best friend.
