Simple Syrup and Its Ten Variations

The base recipe (1:1)

Combine equal parts sugar and water by weight — 200 g of each is a workable batch. Warm gently on the stove or in the microwave until the sugar dissolves. Do not boil; boiling caramelizes the sugar and changes the flavor.

Bottle in a clean glass container and refrigerate. Keeps four to six weeks. A splash of neutral vodka (about 15 ml per 500 ml) extends the life to two months by inhibiting mold.

Rich syrup (2:1)

Two parts sugar to one part water. Sweeter and more viscous. Use in cocktails that need less water volume — an Old Fashioned wants rich syrup because you're already adding no water beyond ice melt.

Some bartenders prefer rich for everything and adjust down the volume in each recipe. Both approaches work.

Demerara syrup

Substitute demerara or turbinado sugar (raw cane) for white sugar. The slight molasses character echoes the barrel notes in aged whiskey and rum. Traditional in Old Fashioneds and Daiquiris made with aged rum.

The syrup is amber-colored and slightly more viscous than white simple.

Honey syrup (3:1)

Three parts honey to one part warm water. Honey by itself is too viscous to integrate into cold cocktails; diluted with warm water it pours cleanly.

Use in Bee's Knees, Gold Rush, Penicillin. Wildflower honey is the workhorse; single-origin honeys (buckwheat, orange blossom) contribute distinct character.

Ginger syrup

Grate 40 g of fresh ginger into 200 g each sugar and water, warm to dissolve, steep 30 minutes off heat, strain. Fiery, spicy, essential for Moscow Mules, Penicillin, Dark and Stormy variations you build from scratch.

Herb syrup

Make a base 1:1 syrup, add a small handful of fresh herbs off heat, steep 15–30 minutes, strain. Mint, basil, thyme, rosemary, and lemon verbena all work; steep by taste — 15 minutes for delicate herbs, 30 for woody ones.

Citrus syrup

Add the peels of one citrus fruit (no pith) to a warm 1:1 syrup, steep 30 minutes, strain. Also possible: oleo saccharum — 100 g of citrus peels macerated with 100 g of sugar for 4 hours to draw out the oils, then bloomed with an equal weight of hot water.

Oleo saccharum is the traditional base of historic punch recipes.

Spice syrup

Toast whole spices — cinnamon sticks, star anise, cardamom pods, cloves, allspice berries — briefly in a dry pan, add to a warm 1:1 syrup, steep 30 minutes to 2 hours, strain.

Cinnamon syrup transforms a Piña Colada. Allspice syrup makes a serious Painkiller.

Vanilla syrup

Split one vanilla bean, scrape seeds into warm 1:1 syrup, add the pod, steep 4 hours off heat, strain. Round, floral sweetness that softens whiskey and rum drinks. Real vanilla bean is expensive; vanilla extract is not a substitute.

Coffee syrup

Add 30 g of dark-roasted coffee beans (whole, cracked with the flat of a knife) to warm 1:1 syrup, steep 20 minutes, strain immediately. Espresso Martinis, whiskey drinks, coffee-forward stirred cocktails.

Longer steep produces bitterness. 20 minutes is the sweet spot.

Storage and labeling

Every syrup gets a dated label. Simple 1:1 lasts 4–6 weeks refrigerated; flavored syrups often shorter because botanicals encourage spoilage. If a syrup develops cloudy strands or a sour smell, discard.

Keep bottles in a dedicated bin so you can see what you have. A home bar with six labeled syrups can build most classic and modern cocktails without buying commercial versions.
