Clove syrup is a warm, aromatic, gently spicy-sweet coffee syrup made by steeping a few whole cloves in a simple sugar syrup, giving a cosy, mulled, almost-holiday warmth that stirs smoothly into lattes, cold brew and hot coffee. To learn how to make clove syrup, you warm equal parts sugar and water until the sugar dissolves, add whole cloves, simmer briefly, then steep off the heat, taste for strength, and strain. That is the whole recipe, and the rest is simply knowing how far to push the spice.
Clove is potent, so this is a syrup where restraint is the real skill. A small handful of buds can perfume an entire bottle, and the goal is a cosy background hum, not a medicinal punch. Below is the full clove syrup recipe, a table for dialling in strength, and a few ways to use your spiced clove syrup once it is bottled.
What is clove syrup?
Clove syrup is a flavoured simple syrup: a sweet base infused with the flavour of whole cloves. Cloves are the dried, unopened flower buds of an evergreen tree native to the islands of Southeast Asia, and they carry one of the most concentrated aromas in the whole spice rack — warm, sweet and woody, with a faintly peppery, almost numbing edge. Steeped into sugar syrup, that character softens into something rounder and cosier: think mulled wine, spiced cider, a clove-studded orange, or the deep back note in a warm baking-spice blend.
Clove has been a prized warm baking and mulling spice around the world for centuries, turning up in festive bakes, spiced fruit, slow-simmered drinks and savoury braises across Europe, the Middle East, North Africa and East Asia. Bottling it as a coffee syrup simply makes that seasonal warmth available in a single spoonful. If you want the wider family of cafe syrups and how they are built, see our guide to coffee syrups explained; here we are focused on the clove version.
How to make clove syrup
The method is the same simple-syrup technique behind most cafe syrups, so if you have made one before this will feel familiar. If you have not, our walkthrough of how to make simple syrup covers the plain base in detail. For clove coffee syrup you are just adding whole buds and steeping, then tasting until the warmth is where you want it.
Ingredients
- 1 cup (about 200 g) white sugar
- 1 cup (about 240 ml) water
- 5 to 10 whole cloves per cup of finished syrup — start low
- Optional: 1 small cinnamon stick or a strip of orange peel, to round it out
Equal parts sugar and water by volume gives a standard 1:1 syrup that pours easily and keeps well. You can use a 2:1 sugar-to-water ratio for a thicker, longer-lasting syrup, but 1:1 is the friendliest place to start. Reach for whole cloves rather than ground: whole buds are far easier to strain out cleanly, while ground clove tends to cloud the syrup and is much easier to overdo.
Step by step
- Warm the base. Combine the sugar and water in a small saucepan over medium heat. Stir until the sugar has fully dissolved and the liquid looks clear — you do not need a hard, rolling boil.
- Add the cloves. Drop in your whole cloves, along with the optional cinnamon stick or strip of orange peel if you are using one.
- Simmer gently. Let it barely simmer for about 5 minutes so the spice begins to release into the syrup.
- Steep off the heat. Take the pan off the heat and let the cloves steep for 20 to 30 minutes. Taste with a clean spoon (once it has cooled enough) every 10 minutes — clove builds fast, so pull it as soon as the warmth reads cosy rather than sharp.
- Strain. Pour the syrup through a fine sieve to catch every bud and any peel, so nothing keeps infusing in the bottle.
- Cool and bottle. Let it come to room temperature, then funnel into a clean, airtight bottle or jar and refrigerate.
If the finished syrup tastes too strong, it is easy to rescue: stir in a little more plain simple syrup or a splash of hot water to dilute it back to a gentle, mulled sweetness.
Cloves per batch and steep time
| Strength | Whole cloves per cup of syrup | Steep off the heat | Best for |
|---|---|---|---|
| Gentle | 5 to 6 | 15 minutes | Everyday lattes, subtle spice |
| Balanced | 6 to 8 | 20 to 25 minutes | Most coffee and steamers |
| Bold | 8 to 10 | 30 minutes | Cold brew, festive mulled flavour |
These are starting points, not rules. Older cloves lose potency, so a jar that has sat in the cupboard a while may need the higher count; fresh, oily buds may need fewer. Whichever you use, taste as you go and stop while it still feels welcoming.
How to use clove coffee syrup
Because clove is intense, use a small pour — start with about half a teaspoon to a teaspoon per drink and adjust from there. A few ideas:
- Lattes and cappuccinos: stir a small spoonful into the espresso before you add the milk, so the spice distributes evenly.
- Cold brew and iced coffee: clove syrup dissolves instantly in cold liquid, where granulated sugar simply would not.
- Hot drip or filter coffee: a bare teaspoon adds a mulled, seasonal note without taking over the cup.
- Spiced steamer: for a coffee-free option, stir it into hot steamed milk for a cosy nightcap.
Clove loves company. It pairs naturally with the rest of the warm baking-spice shelf, so a small splash alongside cinnamon syrup or a spoon of gingerbread syrup builds a fuller mulled or holiday profile — clove supplies the deep, woody back note while cinnamon and ginger bring brightness and heat. A strip of orange peel steeped into the batch nudges the whole thing toward mulled-wine territory.
Storage and shelf life
Cool the syrup fully, keep it in a clean, sealed bottle, and store it in the refrigerator. A 1:1 clove syrup is best used within about two weeks; a thicker 2:1 syrup can keep a little longer. Label it with the date, and give it a quick look and a sniff before each use — if it smells off, turns cloudy or grows anything, pour it out. When in doubt, throw it out. Keeping the bottle clean and cold is really the whole game.
A light note on using clove
Clove is one of the more concentrated spices you can cook with — its aroma comes largely from a compound called eugenol — so the sensible approach is to treat clove syrup as a flavouring and use it sparingly, rather than as any kind of remedy. A little genuinely does go a long way, both for taste and for balance. Responses vary and this is not medical advice; if you are pregnant or breastfeeding, or taking any medication, it is worth checking with your own healthcare provider before making strongly spiced ingredients like this a regular habit. Enjoyed as an occasional spoonful in a good cup of coffee, clove syrup is simply a cosy, aromatic treat.
Once you have the technique down, a spiced clove syrup is one of the quickest ways to make an ordinary coffee feel seasonal — and it opens the door to the whole warm-spice shelf, from cinnamon to gingerbread and beyond.
