One herb syrup makes the whole drink table easier. Make it once, keep it cold, and use it in lemonade, iced tea, sparkling water, matcha, or mocktails all week. The prep feels small until guests show up and plain drinks suddenly taste planned. In fall, the same bottle stirs into hot tea just as easily.

Quick answer

One herb syrup beats five random bottles if you know where it goes next. Make it with sugar, water and a handful of mint, basil or lemon balm, then use it in lemonade, iced tea, bubbles, matcha, or a pitcher drink before making another flavor.

Basic Herb Syrup

This base works for tender herbs like mint, basil and lemon balm. It makes about 8 ounces.

Ingredients:

  • 3/4 cup granulated sugar
  • 3/4 cup water
  • 4 sprigs fresh mint (about 40 leaves), or the same amount of basil or lemon balm
  • Optional: 1 strip lemon peel

Instructions:

  1. Add the sugar and water to a small saucepan over medium heat and stir until the sugar dissolves. Do not let it boil.
  2. Take the pan off the heat.
  3. Add the herb sprigs and lemon peel.
  4. Let them rest in the syrup for 15 minutes, stirring now and then. Leave them longer for a stronger flavor.
  5. Strain into a clean jar.
  6. Chill before using, and keep it in the refrigerator for up to one week.

For rosemary, thyme, or lavender, start with a small sprig or a pinch and taste at 10 to 15 minutes. Woody herbs turn sharp if they sit too long.

One chilled bottle of herb syrup can carry several summer drinks without a pile of flavored mixers.

Drink 1: Herb Lemonade

For two glasses, stir 1/3 cup fresh lemon juice and 1/2 cup herb syrup together, then add 12 ounces cold water and plenty of ice. Garnish with a sprig of the herb you used in the syrup and a lemon slice. For a fizzy version, use sparkling water instead of still water.

It’s the easiest party version because guests can build it themselves. Put the syrup, lemon juice, ice, and sparkling water on the table with a small label.

Drink 2: Herb Iced Tea

Stir herb syrup into cold black tea, green tea, hibiscus tea, or chamomile tea. Start light and add more to taste.

Mint syrup is good with black tea. Basil syrup works with green tea and lemonade. Rosemary syrup is better with strong tea and citrus.

Drink 3: Quick Mocktail Spritz

Add 1/2 ounce herb syrup and 1 ounce fresh lime juice to a glass with ice, then top with 4 ounces sparkling water and stir gently. Garnish with the same herb you used in the syrup.

To make it more grown up, swap the lime for grapefruit. 4 ounces fresh grapefruit juice, 1 ounce basil syrup, and 2 ounces sparkling water make a basil grapefruit spritz.

Drink 4: Matcha or Iced Coffee Sweetener

Mint, lavender, rosemary, and basil syrup all work in iced coffee or matcha if you keep the dose small. Stir a little in before adding milk so the flavor spreads evenly, and taste as you go.

For a measured recipe, use herb syrup in place of the simple syrup in our matcha lemonade and let the lemon and matcha do the rest.

Drink 5: Pitcher Drink For Guests

For a small pitcher, double or triple the herb lemonade:

  • 2/3 cup fresh lemon juice
  • 1 cup herb syrup
  • 24 ounces cold water
  • Ice
  • Sparkling water on the side

Hold the bubbles until people pour their glasses, because sparkling water goes flat in a pitcher, especially outside. You’ll need two batches of syrup for the double, so make it ahead.

Which Herb Should You Use?

Mint is the safest first syrup. It goes with lemonade, tea, sparkling water, cold brew, and fruit.

Basil tastes best with lemon, strawberry, peach, cucumber , and green tea.

Rosemary works with grapefruit, lemon, black tea, pear, and coffee when used lightly.

Lavender needs restraint. Use less than you think and don’t steep it too long.

Lemon balm is gentle and easy with iced tea, sparkling water, and lemonade.

Common Questions

How long does herb syrup last?

About one week in the fridge in a clean jar. If it smells off, looks strangely cloudy, or grows anything, throw it out.

How do I keep herb syrup from tasting grassy?

Don’t boil the herbs. Dissolve the sugar first, take the pan off the heat, add the herbs, and let them rest. Strain once the flavor is clear but not bitter.

Can I use it in hot drinks?

Yes. Stir a spoonful of mint, lemon balm or lavender syrup into hot tea for a cozy fall cup.
