Rosemary Simple Syrup Recipe

Earthy, piney, and just a little bit savory, rosemary simple syrup brings a fresh twist to classic and creative drinks. This easy syrup adds depth to gin cocktails, bourbon drinks, lemonades, and even mocktails with an herbal edge.

I’ve got a massive rosemary bush on the side of my house that I raid for recipes, but a rosemary plant in a pot on the windowsill will work just as well if you are short on space.

When all else fails, you can hit the grocery store’s fresh herb section, but homegrown herbs always taste better than commercially harvested herbs.

Tools for recipe:

• Fine mesh strainer
• Cheesecloth (or this handy strainer set up)
• 2 Mason jars
• Sauce pan

Tips for the Best Rosemary Syrup:

• Start with 3 sprigs for a milder syrup, go up to 5 if you want bold herbal flavor.
• For extra depth, lightly crush the rosemary with your hands before steeping.
• The syrup will have a soft golden hue—this is normal!

How to Use Rosemary Syrup:

• Add to gin, vodka, whiskey or bourbon cocktails (pairs beautifully with citrus)
• Mix with lemon juice and sparkling water for a refreshing herbal soda
• Drizzle over roasted fruit or stir into iced tea for a savory edge
• Try it in a hot toddy or even coffee for a cozy, unexpected twist

How to Make Rosemary Simple Syrup

Ingredients:

• 1 cup water
• 1 cup sugar
• 3–5 rosemary sprigs (fresh)

Instructions:

1. Combine water and sugar in a saucepan over medium heat. Stir until the sugar dissolves.
2. Add the rosemary sprigs and bring the mixture just to a simmer.
3. Turn off the heat and let the rosemary steep for 15–30 minutes, depending on how strong you want the flavor.
4. Strain out the rosemary in a cheesecloth and let the syrup cool completely.
5. Store in a sealed glass container in the fridge for up to 2 weeks (up to one week is better and more likely though).
