Mint Simple Syrup
Cool mint simple syrup for mojitos that’s lightly citrusy and built to do most of the work for you. Fresh spearmint and lime zest is steeped together to create this mint simple syrup so that all you need to mix a mojito is rum or sparkling water and ice.
Another interesting one to try is my sage simple syrup which is an earthy, slightly peppery herbal syrup or my rosemary simple syrup with bold and woodsy flavor that pairs beautifully with citrus and gin-based drinks.
Mojito simple syrup ratio
This mint simple syrup recipe uses a equal parts sugar and water which is exactly right for mojitos. You want the syrup pourable and light enough to blend into a cold drink without making it heavy. This ratio does that without making the mint or lime zest flavors buried under too much sweetness. In a classic mojito the balance between sweet, sour, and fresh is everything.
Get exact sugar, water, and yield amounts for any ratio ā 1:1, 2:1, or 1:2 ā in grams, ounces, or cups.

- Fresh mint leaves – spearmint is the classic mojito mint and what this recipe is built around. Itās sweeter and softer than peppermint. Use loosely packed leaves, stems mostly removed. I won’t recommend dried mint as the flavor is flatter and more muted.
- Lime zest – this is what makes the syrup mojito-ready. It adds the citrus aroma of lime without the acid, which means shelf life stays intact and the flavor stays bright in the bottle. Donāt use lime juice in the syrup itself as heat and time kill fresh citrus quickly and the flavor goes flat within a day or two.
- Granulated sugar – white granulated sugar keeps the mint and lime front and center without adding flavor of its own. Cane sugar works the same way thatās actually quite nice in a mojito mocktail.
- Water – plain tap or filtered. Nothing more to it.
How to make mint simple syrup
Combine the sugar and water in a small saucepan over medium heat and stir gently until the sugar is fully dissolved – youāll see the mixture go from slightly cloudy to clear and glossy, usually around 3 to 4 minutes. Donāt let it boil. A gentle dissolve is all you need and boiling drives off water which throws off your ratio.
Pull the pan off the heat and add the mint leaves and lime zest straight away. The residual heat is what does the steeping work – you donāt need the syrup to be actively cooking to extract the flavor, and leaving it on heat too long turns fresh mint dull, which is the opposite of what you want. Give the mint a very light press with the back of a spoon to bruise the leaves slightly – not a full muddle.
Let it steep while covered for 20 minutes. This is the step most people rush and itās where the flavor actually develops. At the 15 minute mark the syrup will be minty, at 20 minutes itās genuinely fragrant and the lime zest will have added a subtle citrus background that makes the whole thing smell like a mojito in a jar.
Strain through a fine mesh sieve, pressing lightly on the leaves to extract the last of the syrup. Discard the mint and zest. Cool completely before bottling – the syrup will be a pale golden-green and will smell immediately like a fresh mojito. Thatās exactly what you want.
Tips and notes from testing
- Use spearmint specifically, not peppermint. The difference in a mojito is significant – spearmint is sweet and fresh, peppermint is sharp and almost medicinal.
- 20 minutes steep time is the minimum for a properly fragrant syrup. Set a timer rather than guessing – under-steeped mint syrup tastes like sweet water with a hint of mint.
- Press the strained mint gently – firmly enough to get the syrup out, lightly enough not to push bitter plant matter through the sieve. If the syrup looks murky, itās been pressed too hard.
- The lime zest amount matters. Half a lime is the right amount for a background citrus note – a full lime zest starts to dominate and you lose the mint-forward balance that makes this syrup work in a mojito.
Taste and flavor notes
- Sweetness: light to medium – balanced, not heavy
- Primary note: fresh, cooling spearmint
- Secondary note: subtle lime zest brightness
- Overall profile: clean, vibrant, and mojito-ready
How to make a mojito with this syrup
This is the reason the lime zest is in there so building a mojito is straightforward. Youāre not starting from scratch with muddled mint and hoping itās enough.
Classic mojito recipe
In a glass filled with ice, combine 60ml white rum, 25ml fresh lime juice, and 2 tablespoons of this mojito simple syrup. Top with soda water and stir gently. Garnish with a sprig of fresh mint and a lime wedge. Taste and add another half tablespoon of syrup if you want it sweeter.
Mojito mocktail recipe
Same build, no rum. 25ml fresh lime juice, 2 tablespoons of syrup, top with sparkling water over ice. The syrup carries enough flavor that the mocktail doesnāt taste like something is missing. The mint and lime zest do the work that rum normally helps with in terms of aroma and complexity.
Other ways to use this mint mojito simple syrup
This syrup is built around the mojito but it works anywhere you want a clean, fresh mint-citrus sweetener.
- Mint lemonade – stir into fresh lemonade for a cooling, lightly herbal version. The lime zest in the syrup plays nicely with lemon juice without competing.
- Iced tea – pairs well with green tea and white tea where it adds sweetness without weight. Add after the tea has cooled not while hot, or the mint brightness cooks off.
- Sparkling water spritzer – adding to a tall glass of sparkling water with a squeeze of fresh lime. Simple and genuinely refreshing. Good use for leftover syrup toward the end of its shelf life.
Storage and shelf life
Store mint simple syrup in an airtight glass container in the refrigerator. The mint syrup will keep for about 2ā3 weeks.
If youāre making a batch specifically for hosting, you can make it 1 to 2 days ahead rather than day-of, the flavor is noticeably better with a little time to settle. Freeze in ice cube trays (roughly 2 tablespoons per cube) for up to 3 months if you want to keep a batch longer. Drop a frozen cube directly into a glass of sparkling water or a cocktail shaker and it thaws in minutes.
Variations
- Mint julep simple syrup ā use fresh spearmint and a 2:1 sugar ratio for a richer syrup ideal for bourbon cocktails like a mint julep.
- Lime mint syrup ā add lime zest while steeping for citrus brightness which makes a perfect syrup for mint mojito.
- Honey mint syrup ā replace sugar with honey for a floral, softer sweetness.
- Cherry mint syrup ā add some crushed cherries during steeping and strain after.
- Lavender mint syrup ā steep a small pinch of culinary lavender with the mint for a floral-herbal blend.
FAQ
Can I use dried mint instead of fresh?
Not recommended as the flavor will be more muted and slightly earthy. Use about one-third the amount compared to fresh mint.
Can I make a sugar-free mint simple syrup?
You can use a sugar substitute designed for syrups, like Stevia, monk fruit sugar or agave. Though texture and shelf life may differ.
How do I make the syrup stronger?
Lightly muddle the mint before steeping and allow it to infuse longer, tasting periodically.
