Homemade coffee syrup is a flavored simple syrup: equal parts sugar and water, simmered until clear, then flavored with vanilla, spices, caramel or fruit. One cup of sugar and one cup of water make about 1 1/2 cups of syrup, enough for roughly two dozen lattes, and it keeps up to a month in the fridge.
Below you’ll find the base recipe, 6 flavors, a sugar-free version, pump amounts per drink size, a storage chart and a straight comparison with Torani and Monin. The bottles and syrups I mention are research-based picks from Amazon listings checked on October 25, 2026, not things I’ve tested in my kitchen.
What is coffee syrup?
Coffee syrup is a sweet liquid flavoring that dissolves instantly in hot or iced coffee. Most coffee syrups, homemade or store-bought, start as simple syrup (sugar dissolved in water) plus a flavor such as vanilla, caramel or hazelnut. Granulated sugar won’t dissolve well in cold brew, so syrup is the easier sweetener for iced drinks.
The name covers two things:
- Flavored syrup for lattes and iced coffee, the kind Torani and Monin sell.
- Coffee-flavored syrup, made from brewed coffee and sugar, for New England coffee milk (more on that below).
How do you make coffee syrup at home?
To make coffee syrup at home, simmer 1 cup of sugar with 1 cup of water until the sugar dissolves, add your flavor, cool and bottle it. The whole recipe takes about 10 minutes of stove time and yields 1 to 1 1/2 cups, per The Spruce Eats.
- Combine 1 cup (200 g) granulated sugar and 1 cup (240 ml) water in a small saucepan.
- Stir over medium heat until no grains remain, about 3 to 5 minutes.
- Simmer 1 more minute, then take the pan off the heat. Don’t boil it hard, or it thickens toward candy.
- Flavor it: steep spices or a vanilla bean while it cools, or stir in extract once it’s warm.
- Strain and bottle in a clean glass bottle, label it with today’s date and refrigerate.
The table below shows the 3 ratios people mean by “simple” and “rich” syrup, so you can pick by sweetness and shelf life.
| Syrup | Sugar : water | Sweetness | Best for |
|---|---|---|---|
| Simple syrup | 1 : 1 | Standard | Lattes, iced coffee, cold brew |
| Rich syrup | 2 : 1 | About twice as sweet per pump, thicker | Small doses, longer storage |
| Brown sugar syrup | 1 : 1 (brown sugar) | Standard, with molasses notes | Oat milk lattes, shaken espresso |
A 1/4 oz pump of rich 2:1 syrup sweetens about as much as a 1/2 oz of 1:1 syrup, which is handy when your pump bottle is small.
Which coffee syrup flavors can you make?
You can turn the 1:1 base into 6 easy flavors: vanilla bean, brown sugar cinnamon, caramel, toasted hazelnut, pumpkin spice and raspberry. Each one uses a single batch of 1 cup sugar and 1 cup water; only the flavoring step changes.
- Vanilla bean: split 1 vanilla bean and steep it in the hot syrup for 30 minutes, or stir in 2 teaspoons vanilla extract off the heat.
- Brown sugar cinnamon: swap in packed brown sugar and simmer with 2 cinnamon sticks. It’s the syrup behind most brown sugar shaken espresso copycats.
- Caramel: melt the sugar alone until amber, then whisk in the hot water slowly (it spits) and add a pinch of salt.
- Toasted hazelnut: simmer 1/2 cup chopped toasted hazelnuts for 5 minutes, steep 30 minutes and strain.
- Pumpkin spice: add 2 tablespoons pumpkin puree and 1 teaspoon pumpkin pie spice, then strain through a fine sieve.
- Raspberry (fruit): simmer 1 cup berries in the syrup for 5 minutes and strain. Fruit syrups spoil fastest, so make small batches.
For holiday flavors like peppermint and gingerbread, my Christmas coffee bar has the seasonal lineup.

How do you make sugar-free coffee syrup?
The easiest sugar-free coffee syrup uses allulose at the same 1:1 ratio with water, heated just until dissolved. Allulose behaves most like sugar in a syrup; Jaca’s allulose syrup recipe keeps it up to 1 month in the fridge. Monk fruit and stevia blends work too, but they tend to recrystallize when chilled.
- Allulose: 1 cup allulose + 1 cup water, warm until clear, then flavor. Don’t boil it.
- Monk fruit or erythritol blends: expect crystals in the fridge; shake the bottle or rewarm it.
- Liquid stevia: skip the syrup step and add drops straight to the cup.
For a backup bottle, sugar-free store syrups are the simplest route.

What is coffee syrup for coffee milk?
Coffee syrup for coffee milk is a thick, sweet syrup made from brewed coffee and sugar that you stir into cold milk, like chocolate milk. Coffee milk has been Rhode Island’s official state drink since July 29, 1993, according to the state’s facts page, which defines a coffee cabinet as coffee milk blended with ice cream.
To make it, simmer 1 cup of strong brewed coffee with 1 cup of sugar for 10 to 15 minutes until it coats a spoon. Start with 2 tablespoons per 8 oz glass of cold milk and adjust. Autocrat is the bottled syrup most Rhode Islanders grew up on.

How much syrup do you put in coffee?
A good starting point is 1/2 oz of 1:1 syrup (1 tablespoon, or 2 pumps from a 1/4 oz home pump) per 12 oz drink. Café pumps are bigger: Tasting Table puts a café pump at about 1/2 oz, while Monin’s home pumps give 1/4 oz (7.5 ml).
The table below lists the café pump counts Tasting Table reports for Starbucks sizes next to where I’d start at home.
| Drink size | Café pumps (about 1/2 oz each) | Start at home (1/4 oz pumps) |
|---|---|---|
| 12 oz (tall) | 3 | 2 pumps |
| 16 oz (grande) | 4 | 3 pumps |
| 20 oz hot (venti) | 5 | 4 pumps |
| 24 oz iced (venti) | 6 | 4 to 5 pumps |
Iced drinks take a little more, because cold dulls sweetness. For drink-by-drink amounts, my coffee recipes list the syrup for each latte, mocha and iced coffee, and the types of coffee drinks guide explains each base.
How long does homemade coffee syrup last?
Homemade coffee syrup keeps up to 1 month in the fridge in a sealed bottle, per The Spruce Eats. Rich 2:1 syrup holds longer because the extra sugar slows spoilage, while fruit and fresh-herb syrups go first. Room-temperature storage shortens every number below.
The chart below shows the fridge windows I plan around, from the sources in my notes.
| Syrup type | Fridge life | Source |
|---|---|---|
| 1:1 simple and spice syrups | Up to 1 month | The Spruce Eats |
| 2:1 rich syrup | Longer than 1:1 | Cocktail Chart, The Spruce Eats |
| Fruit or infused syrups | About 1 week | Jerry Can Spirits |
| Allulose syrup | Up to 1 month | Jaca |
Throw a syrup out if you see any of these 4 signs:
- Cloudiness in a syrup that was clear.
- Mold spots on the surface or the bottle neck.
- A sour or boozy smell, which means it has started to ferment.
- Bubbles or fizz when you open the bottle.
Is homemade syrup cheaper than Torani or Monin?
Yes, homemade syrup costs less per drink, because 1 cup of sugar makes about 48 quarter-ounce pumps. BrewSift works out sugared Torani at about 53 cents a serving. Store syrups win on shelf life and consistency: an unopened bottle sits in the pantry, while homemade syrup needs the fridge.
| Pick | Best for | Size | Watch out | Where to buy |
|---|---|---|---|---|
| Torani Syrup Trio: Vanilla, Caramel and Hazelnut, with Pumps | Flavored-latte drinkers and new coffee bars | 3 x 750 ml (25.4 fl oz) | Big bottles take shelf space. Plastic bottles, so they look less pretty than glass. | Check Price for Torani Syrup Trio: Vanilla, Caramel and Hazelnut, with Pumps on Amazon (opens in a new tab) |
| Monin Vanilla Syrup, 1 Liter, 2-Pack | Anyone who drinks vanilla lattes most days | 2 x 1 L (33.8 fl oz) (listing) | Pumps are sold separately on this listing; check that your pump fits a 1-liter Monin neck. | Check Price for Monin Vanilla Syrup, 1 Liter, 2-Pack on Amazon (opens in a new tab) |

A sensible split is one store bottle of vanilla for busy weeks and homemade syrup for seasonal flavors. Torani’s 25.4 oz plastic bottles take most universal pumps; Monin’s 750 ml glass bottles need a pump made for Monin glass.
How do you set up syrups on a coffee bar?
Set up syrups on a coffee bar by decanting them into matching pump bottles, labeling each one with the flavor and date, and keeping 3 to 4 everyday flavors beside the machine. Homemade syrups live in the fridge; only shelf-stable store syrups stay on the counter.
My coffee syrup station guide covers pump sizes, racks and which pump fits which bottle. For labels, I’ve rounded up the options in coffee bar labels, and the rest of the setup is in my coffee bar essentials list.

Frequently asked questions
Does coffee syrup have caffeine?
Flavored syrups like vanilla or caramel have no caffeine, because they are sugar, water and flavoring. Syrups made from coffee are different. Monin lists caffeine for its espresso syrup and cold brew concentrates, and a homemade coffee syrup made with brewed coffee carries some of that coffee's caffeine.
Why did my homemade syrup crystallize?
Sugar crystals form when undissolved grains stay on the pan or the syrup is very concentrated, as in a 2:1 rich syrup. Stir until every grain dissolves before it simmers, wipe the pan sides, and add a teaspoon of corn syrup or a squeeze of lemon juice to a batch to slow crystals.
Can you use honey or maple syrup in coffee instead?
Yes. Thin honey 1:1 with hot water so it pumps and mixes into cold drinks, or use pure maple syrup straight from the bottle. Both bring their own flavor, so they suit brown sugar, cinnamon and oat milk drinks better than a clean vanilla latte.
Can I make coffee syrup without a stove?
Yes. Shake equal parts superfine sugar and hot tap water in a sealed jar for 2 to 3 minutes until clear. This cold-process syrup works for vanilla extract or cinnamon flavors, but spices and vanilla beans give more flavor when you simmer them.
