I made one bottle of mint syrup and used it in five different drinks before the week was over: fresh mint lemonade, a watermelon sparkler, mint iced tea, a strawberry mint gin smash, and mojitos with and without rum.
That is the reason I keep coming back to homemade syrups. I am not making a special ingredient for one glass. I am making a concentrated flavor base that can move around the kitchen all week.
This fresh mint simple syrup uses equal parts sugar and water, plenty of fresh mint, and a gentle extraction method. Once the sugar dissolves, the saucepan comes off the heat and the mint steeps in the warm syrup for 20 to 30 minutes. The result tastes clean and distinctly minty instead of dull, grassy, or cooked.
If you want to understand why different ingredients need different syrup methods, start with my guide to making flavored syrups for drinks. This recipe puts the delicate-herb method into practice.

Quick answer: How do you make mint simple syrup?
Combine one cup of sugar and one cup of water in a saucepan. Warm the mixture just until the sugar dissolves, then remove the pan from the heat. Add two lightly packed cups of fresh mint, cover, and steep for 20 to 30 minutes. Strain, cool, and refrigerate.
The recipe makes approximately 1 ½ cups. Start with one to two tablespoons per glass of lemonade or iced tea, or about ¾ ounce in a mojito.
Why this mint syrup tastes fresh instead of cooked
Mint is a delicate herb. It does not need a long simmer to release its flavor, and boiling the leaves in sugar water can push the syrup toward something dark, muddy, or grassy.
The better approach is to use the heat to dissolve the sugar, then step away from it. Once the saucepan comes off the heat, add the mint and cover the pan. The residual warmth extracts the flavor gently, while the lid helps keep more of the mint’s aroma in the syrup instead of allowing it to escape with the steam.
Begin tasting after 20 minutes. If the mint flavor is clear and fresh, strain it. If you want it a little stronger, give it another five to ten minutes. Longer is not automatically better.
Ingredients you need
You only need three ingredients for the syrup:
- Granulated sugar: White sugar gives the mint a clean background. Brown sugar and honey work, but their stronger flavors change the direction of the syrup.
- Water: One cup gives you a standard 1:1 syrup that is easy to mix into tea, lemonade, sparkling water, and cocktails.
- Fresh mint: Use two lightly packed cups of leaves and tender stems. A small handful disappears once the syrup is diluted over ice, so this is the place to be generous.

Spearmint or peppermint?
Spearmint is the easiest choice for mojitos, lemonade, iced tea, and most mocktails. Its flavor is fresh and familiar without feeling too sharp.
Peppermint is stronger and cooler. It can work, but start tasting the syrup earlier and shorten the steep if the menthol character begins to take over.
Garden mint is perfect as long as you enjoy its flavor. Different mint varieties do not taste exactly alike, so taste a leaf before committing the whole bunch.
Can you use the stems?
Tender upper stems are fine. Remove thick or woody lower stems, which add bulk without giving you much useful flavor.
How to make mint simple syrup step by step
1. Prepare the mint
Rinse the mint thoroughly and remove any damaged leaves or thick, woody lower stems. Tender upper stems can stay because they still carry plenty of mint flavor.
2. Dissolve the sugar
Combine one cup of granulated sugar and one cup of water in a small saucepan. Warm over medium heat, stirring occasionally, until the sugar dissolves completely, about two to three minutes.
The mixture does not need to boil. Once the liquid looks clear and no sugar remains on the bottom of the pan, remove it from the heat.
3. Add the mint off heat
Add the fresh mint to the warm syrup and gently press the leaves beneath the surface. Cover the saucepan immediately.
Keeping the pan covered helps trap the fresh mint aroma while the leaves steep.
4. Steep for 20 to 30 minutes
Let the mint steep for 20 minutes, then taste the syrup. If the flavor is clear and strong enough, strain it. If you want more mint flavor, cover the pan again and steep for another five to ten minutes.
Avoid leaving the mint in the syrup for hours. A longer steep can eventually introduce grassy or bitter flavors.
5. Strain, cool, and refrigerate
Pour the syrup through a fine-mesh strainer into a clean jar or bottle. Let the liquid drain without crushing the leaves aggressively.
Cool completely, cover, label with the date, and refrigerate.

How much mint syrup should you use in a drink?
Start with less than you think you need, taste the finished drink over ice, and add more from there. The citrus, tea, fruit, bubbles, and melting ice all change how sweet the syrup tastes.
| Drink | Mint syrup starting point | What to add |
| Mint lemonade | 2 tablespoons | 2 tablespoons lemon juice + 6 to 8 ounces cold water |
| Mint iced tea | 1 to 2 tablespoons | 8 ounces chilled black or green tea |
| Mojito | ¾ ounce | ¾ ounce lime juice + 2 ounces white rum + club soda |
| Virgin mojito | ¾ ounce | ¾ ounce lime juice + 4 to 6 ounces club soda |
| Watermelon sparkler | 1 tablespoon | ½ cup watermelon juice + lime + sparkling water |
| Strawberry mint smash | ¾ ounce | Strawberries + citrus + gin, rum, or sparkling water |
If a drink tastes too sweet, add more tea, water, sparkling water, lemon, or lime. If the sweetness is right but the mint disappears, add another teaspoon of syrup.
Mint lemonade with mint simple syrup
For one glass, combine:
- 2 tablespoons mint simple syrup
- 2 tablespoons fresh lemon juice
- 6 to 8 ounces cold water
- Ice
Stir and taste. Add another spoonful of syrup if your lemons are especially tart, or more water if you want something lighter. A handheld citrus juicer is genuinely useful here if you make lemonade and lime drinks often.
For a sparkling mint lemonade, replace half or all of the still water with chilled sparkling water just before serving.
Mint iced tea with mint syrup
Mint syrup is one of the easiest ways to sweeten cold tea because the sugar is already dissolved. No gritty sugar collects at the bottom of the glass, and the mint flavor is distributed through the whole drink.
Add one to two tablespoons of syrup to eight ounces of chilled black tea or green tea. Pour over ice and add a squeeze of lemon if the tea tastes flat.
Black tea gives you a deeper, more traditional sweet-tea flavor. Green tea keeps the drink lighter and lets the mint come forward. Hibiscus tea makes a tart, bright red drink that usually needs a little more syrup.
If you like building drinks from a flexible tea base, my homemade kombucha guide uses the same Pantry First idea: learn the base method, then change the flavor.
Mojito with mint simple syrup
Mint syrup makes mojitos much easier to repeat, especially when you are serving more than one person. It carries sweetness and mint flavor together, so you do not have to grind sugar into every glass. I still add a fresh mint sprig at the end because aroma is part of what makes a mojito feel so refreshing.
For one mojito, combine:
- ¾ ounce mint simple syrup
- ¾ ounce fresh lime juice
- 2 ounces white rum
- Ice
- 2 to 3 ounces club soda
- Fresh mint and lime for serving
Shake the syrup, lime, and rum with ice in a cocktail shaker, or stir them directly in a tall glass. Add fresh ice, top with club soda, and garnish with mint and lime.
Virgin mojito with mint syrup
Leave out the rum and use four to six ounces of club soda. For more depth, add two ounces of chilled green tea or use ginger beer in place of some of the soda water.
You do not need to label it as the lesser version. It is a crisp mint-lime drink that stands on its own.
Two more drinks from the same bottle
Watermelon mint sparkler
Blend fresh watermelon and strain it if you want a smoother drink. Combine ½ cup watermelon juice, one tablespoon mint syrup, one tablespoon lime juice, and ice. Top with three to four ounces of sparkling water.
Strawberry mint gin smash
Muddle two or three strawberries in a shaker, then add 1 ½ ounces gin, ¾ ounce mint syrup, ¾ ounce lemon juice, and ice. Shake well and strain over fresh ice. Top with a small splash of soda water if you want it longer and lighter.
For a zero-proof version, leave out the gin and add extra sparkling water or chilled tea.





Make-ahead mint mojito pitcher
For eight drinks, combine:
- 1 cup mint simple syrup
- 1 cup fresh lime juice
- 2 cups white rum, optional
- 3 cups cold water or chilled green tea
- 3 to 4 cups club soda, added just before serving
- Lime wheels and mint sprigs
Mix the syrup, lime juice, rum if using, and still water several hours ahead. Refrigerate the base. Add the club soda and garnishes when you are ready to serve, and keep most of the ice in the glasses so the pitcher does not become watery.
This is the kind of make-ahead component that fits naturally into my guide to hosting at home without stress. The welcome drink is already mostly finished, but the bubbles and herbs still feel fresh when guests arrive.
More ways to use mint syrup
Mint syrup is not limited to mojitos. Try it in:
- limeade or cucumber limeade
- sparkling water with lemon or lime
- black tea, green tea, or hibiscus tea
- fruit salad with watermelon, berries, or melon
- strawberry or lemon sorbet
- mint juleps
- gin, rum, bourbon, or vodka drinks with citrus
- iced matcha
- a small batch of popsicles
I used mint syrup over the strawberry mint sorbet in my spring seven-course dinner party, which is a good reminder that a drink syrup can also finish fruit and simple desserts.
If you want a warmer syrup for coffee and fall drinks, my pumpkin spice latte syrup goes in the opposite direction with pumpkin, vanilla, and spices.
Troubleshooting mint syrup
The syrup tastes weak
Use more mint before increasing the heat. A few sprigs may smell fragrant in your hand but disappear once the syrup meets ice, citrus, tea, or sparkling water. Two lightly packed cups give the finished syrup enough flavor to survive dilution.
Should mint simmer in simple syrup?
No. Warm the sugar and water only until the sugar dissolves, then remove the saucepan from the heat before adding the mint. The residual warmth is enough to extract fresh mint flavor without cooking the leaves.
The syrup tastes grassy or bitter
The mint may have stayed in very hot syrup for too long, or the leaves may have been crushed too aggressively during straining. Keep the syrup off heat, begin tasting after 20 minutes, and drain without squeezing every last drop from the leaves.
The syrup turned brown
Some color change is normal, especially after several days. Use fresh mint, add it only after the saucepan comes off the heat, and strain it once the flavor is strong enough. Store the finished syrup cold in a clean, tightly closed container.
The syrup crystallized
Crystals can form if sugar remains on the sides of the pan or if too much water evaporates. Heat only until the sugar dissolves. If the refrigerated syrup develops harmless sugar crystals but otherwise smells and looks normal, warm it gently with a spoonful of water until smooth, then cool it again.
How long does mint simple syrup last?
For the freshest flavor, use refrigerated mint syrup within seven to ten days. It may hold for up to two weeks in a very clean, tightly closed container, but fresh herb syrups lose their bright character before plain simple syrup does.
The University of Maine Cooperative Extension recommends refrigerating flavored simple syrups and using them within one month. I use a shorter window for this recipe because mint flavor is best while it still tastes fresh.
Discard the syrup if you see mold, notice unexpected bubbles or pressure, or smell anything fermented or unpleasant. This recipe is not shelf-stable.
For longer storage, freeze the syrup in small portions for up to three months. An ice-cube tray makes it easy to thaw only enough for one or two drinks. The high sugar content may keep the cubes slightly soft, which is normal.

Frequently asked questions
Do you have to boil mint simple syrup?
No. Heat the sugar and water only until the sugar dissolves. Add the mint after the saucepan comes off the heat so the flavor stays fresher.
Can I use dried mint?
Fresh mint gives the cleanest flavor for this recipe. Dried mint tastes more like tea and can become dusty or bitter. If dried mint is all you have, use much less and strain through a very fine filter, but expect a different result.
Can I use peppermint instead of spearmint?
Yes, but peppermint is stronger and more mentholated. Begin tasting after 10 to 15 minutes and strain as soon as the flavor is where you want it.
How long should mint steep in simple syrup?
Twenty to 30 minutes is a good range for spearmint. Start tasting at 20 minutes. Longer is not automatically better.
How much mint syrup goes in a mojito?
Start with ¾ ounce of mint syrup for a mojito made with two ounces of white rum and ¾ ounce fresh lime juice. Adjust after the club soda and ice are added.
Can mint simple syrup be frozen?
Yes. Freeze it in small containers or ice-cube trays for up to three months. Thaw in the refrigerator.
One bottle, five different drinks
The best part of this recipe is not the syrup by itself. It is the fact that a jar in the refrigerator makes the next drink easier.
Use it with lemon and cold water at lunch. Stir it into iced tea in the afternoon. Add lime and bubbles for a virgin mojito, or add rum when you want the classic version. Blend watermelon or strawberries into the next glass and it changes again.
