How to Make Simple Syrup

Simple syrup is a liquid sweetener made from sugar dissolved in water. It is an essential cocktail ingredient because sugar must be in liquid form to blend evenly with cold drinks — dry granulated sugar barely dissolves in a cold shaker.

What You'll Need

Small saucepan
White granulated sugar
Water
Measuring cups
Glass bottle or jar with lid

Steps

Combine sugar and water

For a standard 1:1 syrup: measure equal volumes of white granulated sugar and water — for example, 1 cup sugar and 1 cup water. For a rich 2:1 syrup: use 2 cups sugar to 1 cup water. Combine in a small saucepan.

Heat gently while stirring

Place the saucepan over medium-low heat. Stir continuously as the mixture heats. The sugar will dissolve into the water as the temperature rises — you do not need to bring it to a full boil. Remove from heat as soon as the sugar is fully dissolved and the liquid is clear.

Tip: You can also make simple syrup without heat: combine sugar and water in a sealed jar and shake vigorously for 1-2 minutes. The 1:1 ratio dissolves easily at room temperature; the 2:1 ratio may take several minutes and some residual cloudiness until fully dissolved.

Cool completely

Let the syrup cool to room temperature before bottling. Pouring hot syrup into a cold refrigerator bottle can cause cracking and introduces steam that adds unwanted water.

Bottle and label

Pour the cooled syrup into a clean glass bottle or jar with a tight seal. Label it with the date and the ratio (1:1 or 2:1). Store in the refrigerator.

Tip: A small squeeze bottle or a bottle with a pour spout makes measuring syrup into a jigger much easier than a wide-mouth jar.

Why Simple Syrup Instead of Sugar

Granulated sugar does not dissolve efficiently in cold liquids. If you add dry sugar to a cocktail shaker, most of it will sit undissolved at the bottom, making the drink inconsistently sweet and leaving gritty residue in the glass. Simple syrup distributes evenly and immediately in any cold drink, giving you precise, repeatable sweetness every time.

The Two Standard Ratios

A 1:1 syrup (equal parts sugar and water by volume) is the standard for most cocktails. It is lighter and pours easily. A 2:1 syrup (two parts sugar to one part water) is richer, thicker, and sweeter per volume — a smaller amount goes further. The 2:1 version also keeps longer because the higher sugar concentration resists microbial growth.

When a recipe calls for "rich simple syrup," it means the 2:1 version. When it just says "simple syrup" with no qualifier, it means 1:1.

Variations

Once you have the basic technique, the same method works for a range of flavor variations that expand what you can make at home.

Demerara syrup replaces white granulated sugar with raw demerara sugar for a deeper, slightly molasses-flavored sweetener that works especially well in whiskey and rum cocktails.

Honey syrup is made with a 1:1 ratio of honey and warm water. It dissolves honey into a pourable syrup that blends smoothly into cold drinks. The Bee's Knees and Gold Rush both use honey syrup.

Flavored syrups are made by adding herbs, spices, or citrus peel to the warm syrup and steeping for 20-30 minutes before straining. Mint syrup, ginger syrup, cinnamon syrup, and lavender syrup are all made this way.

Storage

Store in a clean, sealed glass jar or bottle in the refrigerator. A 1:1 syrup keeps for 2-4 weeks. A 2:1 syrup keeps for up to 4-6 weeks. Adding a small amount of vodka (about 1 tablespoon per cup of syrup) acts as a preservative and extends shelf life without affecting flavor in most cocktails.
