How to Make Matcha Syrup for Iced Lattes & Drinks

The short version of how to make matcha syrup is this: whisk culinary matcha into a smooth paste with a splash of hot water, stir that paste into a warm 1:1 simple syrup off the heat, then cool it and bottle it. What you get is a sweet, vivid-green, grassy green tea syrup you can pour into an iced matcha latte, matcha lemonade, sparkling water or steamed milk, or drizzle over cold foam.

Matcha is finely ground green tea powder, so a matcha syrup is really just matcha suspended in sweetened liquid. The sugar base holds the powder in place, carries its colour and flavour, and keeps everything pourable. Below is the full method, the exact amounts, a quick reference table, and how to keep a bottle fresh.

What matcha syrup is and how a tea-powder syrup works

A flavour syrup is usually just sugar, water and one dominant taste. With a fruit or herb you steep or simmer to pull the flavour out. Matcha is different: it never dissolves the way sugar does, because it is the whole leaf ground to a fine powder. When you make a green tea syrup from matcha, you are suspending those fine particles evenly through a sweet base so they stay put long enough to pour and mix. That is why the finished syrup looks opaque and jade-green rather than clear like a plain sugar syrup.

Because the matcha is suspended rather than dissolved, two things matter more than anything else. First, you have to break up every lump before it goes into the syrup, or you will get gritty flecks. Second, the powder will slowly drift to the bottom of the bottle over hours, so you shake it before each pour. Neither is difficult once you know to expect them.

Use culinary-grade matcha, not ceremonial

Matcha is graded loosely by intended use. Ceremonial grade is the smoothest, sweetest powder, meant for whisking straight into hot water and sipping on its own. Culinary grade is a little more robust and grassy, and it is made to hold up when it is mixed with sugar, milk or acid. For a syrup, culinary grade is ideal: its stronger flavour cuts through the sweetness and it is made to be used generously. Save the ceremonial tin for a plain bowl of matcha and reach for culinary powder here. If your matcha looks dull, brownish or smells hay-like, it is stale, and a stale powder makes a muddy syrup, so start with a bright green tin. For the base itself, this recipe leans on a standard 1:1 sugar syrup, and if you want the base technique on its own, see our guide to how to make simple syrup.

How to make matcha syrup, step by step

This is the core method. It scales up or down cleanly, and the whole thing takes about ten minutes plus cooling. Think of it as two small jobs done side by side: warming a simple syrup, and whisking a lump-free matcha paste, then bringing them together off the heat.

Ingredients and amounts

  • Sugar and water in equal parts, for example 1 cup (about 200 g) sugar to 1 cup (240 ml) water. Plain white sugar keeps the colour true; a golden sugar works but dulls the green.
  • Culinary matcha, roughly 1 to 2 teaspoons per cup of finished syrup. Start with 1 teaspoon for a gentle flavour, go to 2 for a bold, deeply green result.
  • A little extra hot water, about 2 tablespoons (30 ml) at 70 to 80 C (160 to 175 F), just to slake the matcha into a paste. Water hotter than that can make matcha taste bitter.
  • Optional: a tiny pinch of salt to round out the sweetness, or a single drop of vanilla for warmth.

The reference table

IngredientAmount (per cup of syrup)What it does
White sugar1 cup (about 200 g)Sweetens and thickens; holds the matcha in suspension
Water1 cup (240 ml)Dissolves the sugar into a pourable syrup base

Hot water (for paste)2 tbsp (30 ml)Slakes the matcha into a lump-free paste
Salt or vanilla (optional)Pinch or 1 dropRounds out and softens the sweetness

Steps

  1. Make or warm the simple syrup. Combine equal parts sugar and water in a small pan over low-medium heat. Stir until the sugar has fully dissolved and the liquid is clear, then take it off the heat. Do not boil it hard; you just need it warm and dissolved.
  2. Sift the matcha. Push the culinary matcha through a small fine sieve into a separate bowl or jar. This one step removes almost every clump before you add any liquid and is the difference between a smooth syrup and a gritty one.
  3. Whisk a paste. Add the 2 tablespoons of hot water to the sifted matcha and whisk hard with a small whisk, milk frother or fork until you have a smooth, lump-free, bright-green paste with no dry pockets.
  4. Combine off the heat. Pour the matcha paste into the warm (not boiling) syrup and whisk or stir until it is fully blended and evenly coloured. Adding it off the heat protects the delicate matcha flavour.
  5. Season, cool and bottle. Stir in the optional pinch of salt or drop of vanilla. Let the syrup cool to room temperature, then pour it through a funnel into a clean, sealable bottle or jar.

Adjusting strength, colour, and the settling problem

The single biggest lever is how much matcha you add. More matcha means a stronger, more bitter, more intensely green syrup; less means a softer, sweeter, paler one. If your first batch tastes flat, whisk a little more matcha paste into the next one rather than adding more powder directly to the bottle, where it will clump. This is a forgiving matcha syrup recipe, so treat the 1-to-2-teaspoon range as a starting point and tune it to taste.

Expect the syrup to separate. Because the matcha is suspended and not dissolved, the powder drifts down and the bottle develops a paler top and a darker, denser bottom as it sits. This is completely normal and not a sign it has gone bad. Just shake the bottle firmly for a few seconds before every pour to re-mix it. If you like, you can strain the cooled syrup through a fine sieve once more to catch any last grit before bottling; you can also think of the plain-sugar version of this as a matcha simple syrup that simply happens to carry green tea.

How to use matcha syrup

The whole point of bottling the flavour is speed: one pour and a drink is sweetened and coloured at once. A few reliable ways to use it:

  • Iced matcha latte: stir a tablespoon or two into a glass of cold milk (dairy or oat work well) over ice. It is the fastest route to a cafe-style drink, and if you want to build a proper hot or iced milk drink from scratch, our walkthrough on how to make a latte at home covers the milk side.
  • Matcha lemonade: add the syrup to lemonade or to sparkling water with a squeeze of lemon for a tart, fizzy green cooler.
  • Soda: top a spoonful with cold sparkling water for a light, grassy matcha soda.
  • Steamed milk: stir it into warm steamed milk for a quick hot matcha milk, no whisking bowl required.
  • Over foam: drizzle it across the top of a drink for colour, or fold the flavour into a topping. If you would rather build the matcha into the froth itself, see how to make matcha cold foam.

Matcha syrup sits in the same family as vanilla, caramel and brown sugar syrups; for the wider picture of how these flavour bases are built and used, our overview of coffee syrups explained is a good next read.

How to store matcha syrup

Keep matcha syrup in a clean, sealed bottle in the refrigerator. Because it contains no preservatives and the matcha is a fresh plant powder, treat it as short-lived: use it within about one to two weeks. Always shake before use to re-suspend the settled powder. The colour naturally fades from bright jade toward a duller green over time, which is normal, but if the syrup smells off, tastes sour, or shows any mold or fizzing, throw it out. When in doubt, throw it out. Making smaller batches more often keeps the flavour and colour at their best.

A light note on caffeine and food safety

Matcha is real green tea, so this syrup carries caffeine; how much lands in your cup depends on how much matcha you used and how much syrup you pour, and green tea is generally on the moderate side compared with coffee. If you are sensitive to caffeine, avoiding it in the evening, or making drinks for children, keep that in mind and pour a lighter measure. On the food-safety side, the practical rules are simple: use a clean bottle, keep the syrup refrigerated, and when in doubt, throw it out. Responses to caffeine vary from person to person, and this is general information rather than medical advice; anyone who is pregnant or breastfeeding, or who has a specific health condition, should check with their own healthcare provider about caffeine.

Frequently asked questions

Can I use ceremonial matcha to make matcha syrup?
You can, but culinary-grade matcha is the better choice for a syrup. Its more robust, grassy flavour stands up to the sugar and holds its colour when mixed. Save smoother, sweeter ceremonial grade for whisking straight into hot water and drinking on its own.
Why is my matcha syrup lumpy or gritty?
Lumps come from adding matcha powder directly to liquid. Sift the matcha through a fine sieve first, then whisk it with a splash of hot water into a smooth, lump-free paste before stirring that paste into the warm syrup. If any grit remains, strain the cooled syrup once through a fine sieve.
Does matcha syrup have caffeine?
Yes. Matcha is real green tea, so the syrup carries caffeine. How much reaches your cup depends on how much matcha went in and how much syrup you pour. Green tea is moderate compared with coffee, so pour a lighter measure if you are caffeine-sensitive or making drinks in the evening. Responses vary and this is not medical advice.
How long does homemade matcha syrup last?
Keep it in a clean, sealed bottle in the refrigerator and use it within about one to two weeks. It has no preservatives, so treat it as short-lived. Shake before each pour to re-mix the settled powder, and discard it if it smells off, tastes sour, or shows any mold or fizzing.
Why does matcha syrup separate in the bottle?
Matcha is suspended in the syrup rather than dissolved, so the fine powder gradually drifts to the bottom and the top layer looks paler. This is completely normal and not a sign it has spoiled. Just shake the bottle firmly for a few seconds before every use to blend it back together.
