If you want to know how to make blood orange syrup, the short answer is simple: it is a deep ruby, sweet-tart citrus syrup with berry-like notes, made by gently simmering fresh blood orange juice and zest with sugar and water. The result is a jewel-coloured syrup that stirs beautifully into iced coffee, an espresso tonic, iced or green tea, lemonade, sparkling water and cocktails. Below you will find a reliable blood orange syrup recipe, how it differs from a plain orange one, and how to keep it fresh.
The whole thing takes about 15 minutes of active work plus a little steeping and cooling time, and it needs no special equipment beyond a saucepan, a fine strainer and a clean bottle. If you have ever stirred up a basic simple syrup, you already know the rhythm. This is a fruit-forward cousin with a dramatic colour and a flavour that leans tart in a way a standard orange syrup rarely does.
What blood orange syrup is (and how it differs from plain orange syrup)
Blood oranges are a winter citrus prized around the Mediterranean, especially in Italy and Spain, where varieties such as Moro, Tarocco and Sanguinello ripen through the cooler months. Their flesh turns a dramatic crimson to burgundy thanks to natural anthocyanin pigments, and the flavour carries a distinct raspberry or berry edge alongside the usual orange sweetness. That combination is exactly why a blood orange syrup tastes more complex, and looks far more vivid, than a syrup made from an everyday navel or Valencia orange.
A plain orange syrup is bright, sweet and cheerful. A blood orange version is sweet-tart, a touch darker in flavour, and pours a rich ruby-pink rather than a pale gold. If you want the classic, all-purpose citrus version, that belongs to our guide on how to make orange syrup, and the wider family of coffee-shop syrups is covered in coffee syrups explained. This page is specifically the blood orange one.
The single most important technique point is the zest. The fragrant citrus oils that make the syrup smell alive live in the coloured outer peel, not in the juice. So you want to include a little zest, but stop at the coloured layer and avoid the bitter white pith underneath. Add too much zest, or dig into the pith, and the syrup turns harsh. The other half of the craft is simply to taste as you go: blood oranges vary a lot in sweetness from fruit to fruit and week to week, so check the sweet-tart balance and adjust before you bottle it.

Ingredients you will need
This makes a small batch, roughly a jar's worth. It is built like a fruit-juice-forward simple syrup, so the ratios are easy to remember and easy to scale up or down.
- About 1 cup (240 ml) fresh blood orange juice — roughly 3 to 5 blood oranges, depending on size and juiciness.
- Zest of 1 to 2 blood oranges — the coloured outer peel only, no white pith.
- About 1 cup (200 g) granulated sugar — roughly equal parts sugar and liquid.
- About 1/2 cup (120 ml) water — to loosen the sugar before the juice goes in.
- Optional: a small squeeze of lemon juice — a little acidity brightens the colour and sharpens the flavour, in the same spirit as our lemon syrup.
If you want a paler, cleaner blood orange simple syrup with no pulp cloudiness, strain the juice through a fine sieve before you start. For a deeper, jammier syrup, leave a little pulp in.
How to make blood orange syrup, step by step
- Wash and zest first. Rinse the oranges, then zest 1 to 2 of them with a fine grater or zester, taking only the coloured peel. Set the zest aside.
- Juice the oranges. Halve and squeeze enough fruit to reach about 1 cup of juice. Strain out the seeds and, if you like a clear syrup, most of the pulp.
- Warm the sugar and water. In a small saucepan, combine the sugar and water over medium heat. Stir until the sugar fully dissolves and the liquid turns clear, but do not let it boil hard.
- Add the juice and zest. Pour in the blood orange juice and drop in the reserved zest. Bring the mixture to a bare simmer.
- Simmer gently. Let it simmer softly for 5 to 8 minutes, just enough to marry the flavours and thicken slightly. Keep it gentle; a hard boil dulls the fresh citrus character and darkens the colour.
- Steep off the heat. Take the pan off the heat and let the zest steep in the warm syrup for 10 to 15 minutes. This pulls out more of those fragrant oils.
- Taste and adjust. Check the sweet-tart balance. If it is too sweet, add a small squeeze of lemon; if too sharp, a little more sugar dissolved in gently.
- Strain and cool. Pour the syrup through a fine strainer into a clean bowl or jug to remove the zest and any pulp. Let it cool to room temperature.
- Bottle it. Transfer to a clean, airtight bottle or jar and refrigerate.
That is the entire blood orange syrup recipe. From here, the only variable worth fussing over is your fruit: sweeter oranges need a touch less sugar, tarter ones a touch more, so trust your taste over the exact numbers.
How to use blood orange syrup for coffee and drinks
The whole point of keeping a bottle in the fridge is how many drinks it lifts. Because the flavour is citrus-forward and a little tart, it plays especially well with cold, fizzy and iced things. To use blood orange syrup for coffee, start with about a tablespoon and adjust to taste.
- Iced coffee: stir a spoonful into iced coffee or cold brew for a citrus-bright lift; it suits milk and oat milk alike.
- Espresso tonic: build a shot of espresso over ice and tonic water, then add the syrup for a sunset-coloured, bittersweet refresher.
- Iced and green tea: sweeten iced black or green tea with it instead of plain sugar for a citrus tea cooler.
- Lemonade and sodas: add to lemonade or top with sparkling water for a homemade blood orange soda.
- Cocktails and mocktails: it shines in a spritz, a margarita, a gin-and-soda, or an alcohol-free version of any of them.
A drizzle over yoghurt, pancakes or a fruit salad works too. If you want to build a small shelf of house syrups alongside this one, keep a few contrasting flavours on hand so every drink has a match, and reach for the tart citrus one whenever a cup tastes a little flat.
Storage and shelf life
Because this is a fresh-fruit syrup with no preservatives, treat it like something perishable. Keep it in a clean, sealed bottle in the refrigerator and use it within about 1 to 2 weeks. The colour will naturally deepen over a few days, which is normal.
Always pour rather than dip, so nothing contaminates the bottle. Check before each use: if you see any fuzz, cloudiness that was not there before, or an off or fermented smell, throw it out. When in doubt, throw it out. A small squeeze of lemon and a scrupulously clean bottle both help it keep a little longer, but they do not make it shelf-stable at room temperature.
A light note on food safety
This one is about handling, not health. Wash the whole oranges before zesting, since anything on the peel can transfer when you grate it. Let the syrup cool fully before you seal the bottle, so condensation does not encourage spoilage. And keep it cold between uses.
Blood oranges are simply a citrus fruit here, enjoyed for their colour and their sweet-tart flavour rather than any specific benefit, and individual responses to any food vary; this is general food-and-drink information, not medical advice. If you take regular medication or have any dietary concerns, follow the guidance of your own healthcare provider. Beyond that, a jar of homemade blood orange simple syrup is one of the easiest ways to make a plain glass of iced coffee or sparkling water feel like a treat.
