Gritty sugar at the bottom of a pitcher of iced tea taught me why every home drink-maker needs a good simple syrup recipe. I was nineteen, hosting my first family barbecue, and I stirred four spoonfuls of granulated sugar into cold tea. It never dissolved. My aunt slid a jar of clear syrup out of her fridge and said, “Dissolve it first, love.” I have kept a bottle in my own fridge ever since!
This page is the base for everything else in my syrup series: the 1:1 ratio, the rich 2:1 version, a no-heat method, and how long each keeps. Once you have this simple syrup recipe down, the flavored versions below take five extra minutes each, and every one of them starts from the same simple syrup recipe.
Why This Simple Syrup Recipe Works
Sugar dissolves far faster in warm water than in cold, and it stays dissolved once the mixture cools. Equal parts sugar and water by volume (1 cup of each) gives a syrup that is about 46 percent sugar by weight. That is sweet enough to sweeten a drink evenly, yet thin enough to pour straight from the bottle.
I heat the water only until the liquid turns clear, which takes about three minutes. Boiling is unnecessary, and it evaporates water, so the ratio drifts every minute you leave it on the stove. Keep the heat low and this simple syrup recipe gives you the same result every batch.
Simple Syrup vs Rich Simple Syrup
Rich simple syrup uses two parts sugar to one part water, about 63 percent sugar by weight. It is thicker, sweeter per spoonful, and lasts far longer in the fridge. Use 1:1 for iced tea, lemonade and coffee. Reach for rich when you want a small splash of sweetness that will not water down a mocktail.
Simple Syrup Ratio Cheat Sheet
The ratio is the whole trick, so here it is in plain words. One cup sugar to one cup water is the everyday syrup. Two cups sugar to one cup water is rich. Half a cup sugar to one cup water is a light syrup for delicate fruit drinks where you want only a hint of sweetness.
If you count in grams, use 200 g sugar to 240 ml water for the 1:1 version. A digital scale beats measuring cups every time, and it is the one tool I would tell a beginner to buy before any fancy gadget. Weigh once and this simple syrup recipe becomes automatic.
How to Make Simple Syrup Without Boiling
Hot water is faster, but you can skip the stove entirely. Put equal parts superfine sugar and warm tap water in a jar, seal it, and shake for about two minutes. The syrup comes out slightly cloudy with tiny air bubbles, and it clears after an hour in the fridge. Regular granulated sugar works too, though it needs closer to four minutes of shaking.
Key Ingredient Notes
Plain white granulated sugar gives the cleanest, most neutral syrup, so it is my default. Its main component is sucrose, which is why a basic simple syrup tastes sweet and nothing else. Raw or turbinado sugar adds a light caramel note and a pale amber color. For a deeper, molasses-heavy flavor, see my brown sugar syrup.
Water matters more than people think. I use filtered water from a pitcher, because chlorine from a strong tap can come through in a clear syrup. Honey and maple both work as replacements, but use only three-quarters as much, since both are sweeter than sugar.
What I Learned Making This Simple Syrup Recipe
On a rainy Sunday in February I made a double batch for my sister’s baby shower drink table. I left the pot on medium heat while I frosted cupcakes, and ten minutes later it had reduced by a third and smelled faintly of caramel. Cooled, it set into a cloudy, sticky syrup that clouded every glass of lemonade it touched.
I poured it out and started over with a timer. Three minutes on low, stir, done. The clear batch smelled like nothing at all, which is exactly what a neutral base should do. I now stand at the stove for the whole three minutes, spoon in hand.
How Long Does Simple Syrup Last?
In a clean, sealed bottle in the fridge, my 1:1 syrup stays fresh for about four weeks. Rich syrup lasts up to six months, because the extra sugar leaves less water for anything to grow in. Toss either one at the first sign of cloudiness, a sour smell or floating specks.
Flavored Variations of This Simple Syrup Recipe
Every one of these starts from the base above, with a different flavor steeped or simmered in:
- Vanilla syrup for lattes and cream soda
- Strawberry syrup for lemonade and matcha
- Brown sugar syrup for iced coffee
- Lavender syrup for tea and sparkling water
- Pumpkin spice syrup for autumn lattes
- Coconut syrup for iced drinks and sodas
- Peach syrup for iced tea
- Blueberry simple syrup for lemonade and sparkling water
- Mint simple syrup for mojito-style mocktails
- Rosemary simple syrup for herbal sodas
- Ginger simple syrup for ginger ale and mules
- Almond syrup for lattes and orgeat-style drinks
- Blackberry simple syrup for sodas and sparkling drinks
How to Use Simple Syrup
Sweeten a pitcher of iced tea, and it blends in evenly with no gritty bottom layer. Stir a tablespoon into my strawberry lemonade or my iced matcha latte when you want a controlled sweetness. Fizzy drinks are where a homemade syrup shines most, as in my homemade ginger ale and homemade cream soda.
Troubleshooting This Simple Syrup Recipe
Crystals form in the bottle: Stray sugar grains on the pot wall seeded them. Wipe the rim before sealing, and add a squeeze of lemon juice to rich syrup to keep it smooth.
Syrup looks cloudy: Either the sugar was not fully dissolved or the pot boiled too long. Heat gently until clear, and strain through a fine mesh sieve if any specks remain.
Syrup is too thin or too thick: Check the ratio. Warm thick syrup thins with a spoonful of hot water, and a thin batch goes back on the heat with extra sugar stirred in.

The short version of this simple syrup recipe: combine 1 cup sugar and 1 cup water, heat gently for about three minutes until clear, then cool and bottle. Keep it in the fridge for up to four weeks, or make the 2:1 rich version to keep it for months. A good simple syrup recipe takes five minutes and improves nearly every drink you make.
Simple Syrup
Equipment
- 1 Small saucepan
- 1 Glass bottle or jar with lid
- 1 Small funnel
Ingredients
For the Syrup
- 1 cup granulated sugar 200 g; use 2 cups for rich 2:1 syrup
- 1 cup filtered water 240 ml
Instructions
Dissolve the Sugar
- Measure 1 cup of granulated sugar and 1 cup of filtered water. Weigh them if you have a scale: 200 g sugar and 240 ml water.
- Pour the sugar and water into a small saucepan and stir once to wet all the sugar.
- Set the pan over low to medium-low heat. Do not let the liquid reach a rolling boil.
- Stir for about 3 minutes, until every grain has dissolved and the liquid looks completely clear.
Cool and Store
- Take the pan off the burner and let the syrup cool for 15 minutes, uncovered.
- Use a funnel to pour the cooled syrup into a clean glass bottle or jar, wiping the rim so no sugar grains cling to it.
- Seal the bottle and write the date on a piece of tape.
- Store in the fridge for up to 4 weeks. Shake gently before each use.

Frequently Asked Questions
Is simple syrup 2 to 1 or 1 to 1?
Both exist. Standard simple syrup is 1:1, one part sugar to one part water, and suits tea, lemonade and coffee. Rich simple syrup is 2:1, two parts sugar to one part water, and suits mocktails because it is sweeter, thicker and keeps far longer in the fridge.
Do you have to boil water to make simple syrup?
No. Warm water and a jar are enough. Combine equal parts superfine sugar and warm water, seal, and shake for about two minutes until clear. Heating gently on the stove for three minutes is faster for granulated sugar, but a hard boil only evaporates water and shifts the ratio.
How long is homemade simple syrup good?
A 1:1 syrup keeps about four weeks in a clean, sealed bottle in the fridge. Rich 2:1 syrup lasts up to six months. Discard either one if it turns cloudy, smells sour, or shows any floating specks or mold, and never top up an old bottle with fresh syrup.
What is the best sugar for simple syrup?
Plain white granulated sugar gives the cleanest, most neutral syrup and works in every drink. Superfine sugar dissolves fastest without heat. Turbinado or demerara adds a light caramel note, and brown sugar gives a deep molasses flavor that suits coffee and spiced drinks.
Can you boil simple syrup too long?
Yes. Boiling drives off water, so the syrup gets thicker and sweeter than the ratio you planned, and the sugar can begin to caramelize or crystallize when it cools. Heat only until the liquid runs clear, about three minutes on low heat, then take it off.
What is the formula of simple syrup?
The formula is equal volumes of sugar and water. In practice that means 1 cup granulated sugar to 1 cup water, or 200 g sugar to 240 ml water. Stir over low heat until every grain dissolves, cool it, and bottle it. That yields about 1.5 cups of syrup.
