Make a batch to store in the fridge for several weeks (or up to a month sometimes!) and you’ll have it on hand to use whenever you need it.
WHAT IS ROSEMARY SYRUP?
Before diving into what rosemary simple syrup is, let’s get to the basics of what ‘simple syrup’ is. Simple syrup is a sweetened liquid, made by dissolving equal parts water and sugar together…resulting in…you guessed it, a syrup consistency.
Rosemary syrup is a simple syrup that has been infused with fresh rosemary for a vibrant, herby flavor. Rosemary Simple Syrup tastes like rosemary; slightly minty, with a hint of lemon and pine, which is a little woodsy and peppery. It’s a strong, hearty herb, one that’s cozy in the wintertime especially.
HOW TO MAKE ROSEMARY SIMPLE SYRUP
Making homemade simple syrup truly is one of the easiest ways to add flavor to homemade cocktails, coffee, lattes, tea, and more. It requires only a saucepan and a little simmering before you have a wonderful sweet syrup.
You will only need three simple ingredients to make it:
- fresh rosemary sprigs
- granulated sugar
Yes, seriously, that’s it! It’s super easy to whip up a batch to have on hand whenever you need it. It’s also much more cost-effective than buying it from the store.
Simple Syrup Recipe Steps
Combine water, sugar, and fresh rosemary sprigs in a saucepan (photos 1-2). Bring the saucepan to a simmer, stirring occasionally, until the sugar is dissolved. Let it simmer for about a minute, but it doesn’t need to be at a rolling boil.
Remove the saucepan from the heat and let the simple syrup cool with the rosemary sprigs in the syrup (photo 3). The longer you let it sit, the more rosemary flavor will continue to infuse in the syrup – this is how you “extract” the rosemary flavor. Do not use it right away, do let it rest for at least 30 minutes.
Remove the rosemary sprigs and transfer the syrup to a jar or airtight container for storage. I do strain the syrup, too, to remove any additional small debris pieces that may be in the syrup from the rosemary (photo 4).
WAYS TO USE ROSEMARY SIMPLE SYRUP
You can experiment with many different ways to use this fragrant syrup. While simple syrups are often added to cocktails for a little sweetness, and in this case flavor, they are not exclusively a cocktail ingredient. Here are a variety of ways to use it (yes, including cocktails!).
Honestly, there are so many ways to experiment with this simple syrup. Use it in place of simple syrup in your favorite cocktail recipes that could benefit from a hint of rosemary. These are a few of my favorites:
- Cranberry Rosemary Prosecco
- Lavender French 75 – using a bit of rosemary, too
- Cranberry Ginger Cocktail – using half ginger and half rosemary
- Rosemary Mojitos
- Great with bourbon, gin, or vodka drinks!

HOW TO STORE (AND HOW LONG IT LASTS)
Store rosemary syrup in a clean (or sanitized) glass jar or another airtight container, preferably glass. Place it in the fridge and it will last for about 3-4 weeks, as long as no other contaminants are added, like additional water, which will create mold more quickly.
If you notice any mold spots on the syrup, it’s time to pitch it and make a new batch.
Simple syrup will eventually go bad, but it will last for quite a long time if stored properly in an airtight container in the fridge without any contamination (like water).
It will last for about 3 weeks, sometimes 4, in the fridge. If you notice any small mold spots, it’s time to pitch it and make a new batch.
This recipe is intended for fresh rosemary, as it has the freshest, most vibrant rosemary flavor and thus infuses best in the simple syrup.
Rosemary Simple Syrup
- 1 cup granulated sugar
- 1 cup water
- 6-8 rosemary sprigs, approximately 5 inches each
- In a small saucepan, bring sugar, water, and rosemary springs to a simmer until sugar is dissolved, then simmer for one to two additional minutes. Remove from heat and let sit for 30 minutes to an hour. The longer it sits the more flavorful it will be!
- Strain the liquid into an airtight container to remove any particles and rosemary leaves. Store in an airtight container – like a glass jar – in the fridge. It should last for 3-4 weeks if stored properly.
- This ratio makes approximately 1 1/2 cups of simple syrup. Halve the recipe and you’ll have approximately 3/4 cups simple syrup.
