Before diving into the full method, watch this quick video guide on how to make simple syrup. It’s a step-by-step visual walkthrough that makes the process even easier:

What Is Simple Syrup?

Simple syrup, also known as sugar syrup, is a liquid sweetener made by dissolving sugar in water.  It blends seamlessly into cold beverages, making it ideal for cocktails, mocktails, and iced coffee. Its straightforward formula makes it both easy to prepare and endlessly versatile.

When making simple syrup, there are two common ratios: 1:1 and 2:1 simple syrup.

1:1 Simple Syrup 

Equal parts sugar and water. This standard version is lighter and works well in most whiskey cocktails where you want a touch of sweetness without overpowering the drink.

2:1 Rich Simple Syrup 

Two parts sugar to one part water. This thicker syrup is more concentrated and is ideal for whiskey-based cocktails like Old Fashioneds, where a richer, smoother mouthfeel is preferred.

Choosing between 1:1 and 2:1 depends on the whiskey drink you’re making: lighter, refreshing cocktails often use 1:1, while spirit-forward classics benefit from the extra depth a 2:1 syrup provides.

Simple Syrup Recipe (1:1 Ratio)

Ingredients:

1 cup granulated sugar

1 cup water

Instructions:

  • Combine sugar and water in a saucepan over medium heat.
  • Stir until the sugar is fully dissolved. Do not boil.
  • Let it cool, then transfer to a clean, airtight container.
  • Store in the refrigerator.

 

That’s it! You’ve made homemade simple syrup in under 10 minutes.

How to Store Simple Syrup

For best results, store your simple syrup in a sterilised glass bottle or jar in the fridge. When stored properly, a basic simple syrup shelf life is about 1 month.

FAQ: All About Simple Syrup

What is simple syrup?

Simple syrup, also known as sugar syrup, is a liquid sweetener made by dissolving sugar in water. It’s commonly used to sweeten beverages, especially cold ones like cocktails, mocktails, and iced coffee, because it mixes more easily than granulated sugar. Simple to make and incredibly versatile, it’s a staple in many kitchens and bars.

Do you have to boil simple syrup?

No, it only needs to be heated enough to dissolve the sugar. Boiling isn’t required and can risk caramelising the sugar.

What is the difference between hot-process and cold-process simple syrup?

Hot-process involves heating sugar and water together; cold-process mixes until dissolved. Hot-process lasts longer, but cold-process preserves delicate flavours better.

How long does simple syrup last?

Typically about 1 month when stored in a clean, airtight container in the refrigerator.

How should simple syrup be stored?

In a sterilised, airtight container in the refrigerator to prevent spoilage.

Can you flavour simple syrup, and how?

Yes! You can add herbs, spices, fruits, or flavored sugars during or after heating your simple syrup. If you want inspiration, check out the Jameson cocktail recipes to see where an infused syrup could fit.

What are the common ratios of sugar to water in simple syrup?

A standard simple syrup ratio is 1:1, but a richer 2:1 syrup is used when you want a thicker, more concentrated sweetener, especially for spirit-forward cocktails like an Old Fashioned.

Can you buy simple syrup or is it better to make it at home?

You can buy simple syrup at most supermarkets or online, but making it at home is quicker, cheaper, and allows you to control the flavour and freshness. Plus, homemade simple syrup is free of preservatives and perfect for customising with herbs, spices, or fruit to suit your favourite whiskey cocktails.
