Coffee Syrups at Home: How to Make Them and How Much to Use
Homemade coffee syrup is 1:1 simple syrup plus flavor. Use 1½–2 tbsp in a 12 oz latte, about 3–4 pumps. Methods, amounts per drink, pump math and storage.
To make coffee syrup, dissolve 1 cup of sugar in 1 cup of water, then add flavor: steep a vanilla bean, simmer cinnamon sticks, or caramelize the sugar first. Use 1½–2 tablespoons (22–30 ml) in a 12 oz latte, which is the same as 3–4 pumps from a café-style pump. A batch costs a fraction of a bottle from the store and keeps about 3 weeks in the fridge.
The basic method
Every coffee syrup starts with classic simple syrup: equal parts sugar and water, warmed until clear. The flavor goes in one of five ways.
| Method | How it works | Try it with |
|---|---|---|
| Steep | Pour hot syrup over the flavoring, cover, steep 30–60 minutes, strain | Vanilla, hazelnut |
| Simmer | Simmer whole spices or ginger in the water 10 minutes, add sugar, steep, strain | Cinnamon, chai, gingerbread |
| Caramelize | Cook dry sugar to deep amber, then whisk in hot water | Caramel |
| Swap the sugar | Use brown sugar, demerara or maple in place of white sugar | Brown sugar, maple |
| Stir in | Add extract or cocoa to a finished syrup | Peppermint, chocolate |
A few rules apply to all of them:
- Use whole spices, not ground. Ground cinnamon never dissolves and leaves sludge at the bottom of every cup.
- Add extracts after the syrup cools a little. Heat drives off the aroma.
- Add a pinch of salt. It makes caramel, brown sugar and chocolate syrups taste rounder, like the café versions.
- Strain well. A fine strainer lined with a coffee filter catches the specks that clog pumps.
How much syrup per drink
These amounts are for 1:1 syrup. Start at the low end, taste, and adjust next time.
| Drink | Syrup | Pumps (¼ oz) |
|---|---|---|
| Espresso or cortado | 1–2 tsp (5–10 ml) | 1 |
| 8 oz hot coffee | 2–3 tsp (10–15 ml) | 1–2 |
| 12 oz latte or cappuccino | 1½–2 tbsp (22–30 ml) | 3–4 |
| 16 oz latte | 2–2½ tbsp (30–37 ml) | 4–5 |
| 12 oz iced coffee or cold brew | 1–2 tbsp (15–30 ml) | 2–4 |
| 16 oz iced latte | 2–3 tbsp (30–45 ml) | 4–6 |
| Shaken espresso (2 shots) | 1½–2 tbsp (22–30 ml) | 3–4 |
| Cold foam (one drink) | 1 tbsp (15 ml) frothed with 3 tbsp cream and 2 tbsp milk | 2 |
For hot drinks, stir the syrup into the espresso before adding milk, so it mixes evenly. For iced drinks, add it to the espresso or cold brew before the ice, because cold milk and ice slow mixing. If you use rich 2:1 syrup, use about two-thirds of these amounts.
Pump math
A standard café syrup pump dispenses about ¼ oz (7.5 ml), which is half a tablespoon. That makes the conversion easy.
| Pumps | Ounces | Milliliters | Tablespoons |
|---|---|---|---|
| 1 | ¼ oz | 7.5 ml | ½ tbsp |
| 2 | ½ oz | 15 ml | 1 tbsp |
| 3 | ¾ oz | 22 ml | 1½ tbsp |
| 4 | 1 oz | 30 ml | 2 tbsp |
| 5 | 1¼ oz | 37 ml | 2½ tbsp |
| 6 | 1½ oz | 45 ml | 3 tbsp |
How many pumps of syrup in a latte?
The common chain-café standard is 3 pumps in a 12 oz drink, 4 in a 16 oz, 5 in a 20 oz hot drink and 6 in a 24 oz iced drink. That's roughly ¼ oz of syrup for every 4 oz of drink. Many people find that sweet and ask for one or two fewer.
Check your own pump
Home pump bottles vary a lot. Some put out ¼ oz, others closer to ⅓ oz (10 ml) or more. Pump four times into a jigger or measuring spoon: if it fills 2 tablespoons, you have a standard ¼ oz pump. If not, adjust your pump count.
Making it taste like the café
Bottled café syrups are usually a little denser than homemade 1:1 syrup, closer to rich syrup, and they're often more strongly flavored. To close the gap:
- Weigh your sugar and make the syrup 1:1 by weight, which is slightly sweeter and thicker than cups.
- Add more flavor, not more syrup. An extra teaspoon of vanilla extract per batch gives coffee-shop strength without making the drink sweeter.
- Toast spices and nuts before simmering for deeper flavor.
- Froth the milk properly. Even an inexpensive handheld frother makes a homemade latte feel like a café one.
Storing coffee syrups
Most coffee syrups keep about 3 weeks in the fridge. Syrups with fresh ingredients, such as pumpkin spice, keep about a week. A pump bottle makes the syrup easy to use every morning, but syrup dries inside the pump tube, so rinse the pump with hot water each time you refill it. If you keep pump bottles on the counter for convenience, only fill them with what you'll use in a day or two and keep the rest in the fridge.

FAQ
How do you make coffee syrup at home?
Dissolve 1 cup of sugar in 1 cup of water over medium heat, then flavor it: steep a split vanilla bean, simmer whole cinnamon sticks, or caramelize the sugar first. Strain, cool, bottle and refrigerate.

Cafés typically use 3 pumps for a 12 oz drink, 4 for 16 oz, 5 for a 20 oz hot drink and 6 for a 24 oz iced drink. One standard pump is about ¼ oz (7.5 ml).
How much is one pump of syrup?
A standard café pump dispenses about ¼ oz (7.5 ml), or half a tablespoon. Home pump bottles vary, so measure four pumps into a spoon to check.
How long does homemade coffee syrup last?
Most homemade coffee syrups last about 3 weeks in the fridge in a sealed bottle. Syrups made with purée, like pumpkin spice, last about a week.
