Simple syrup is an incredibly useful ingredient to have on hand in the kitchen. It’s made by mixing equal parts sugar and water and stirring until the sugar dissolves. Simple syrup can be used to sweeten drinks, desserts, and more. But since it’s basically just sugar water, simple syrup won’t last forever. Here’s how to properly store simple syrup for maximum freshness and shelf life.
Should You Refrigerate Simple Syrup?
Yes, you should store simple syrup in the refrigerator after making it. The refrigerator temperature helps slow down the growth of bacteria and mold in the syrup. Simply transfer your finished simple syrup into an airtight container like a mason jar or bottle with a tight-fitting lid. Make sure the container is completely clean before using. Then store it in the fridge.
How Long Does Simple Syrup Last in the Fridge?
Properly stored simple syrup will last for about 1 month in the refrigerator before going bad. If you see any mold growing in the syrup or it smells or tastes off, it’s time to toss it.
Can You Freeze Simple Syrup?
Freezing is a great way to extend the shelf life of simple syrup even longer. Simple syrup freezes well because of its high sugar content. Pour the syrup into freezer-safe containers like mason jars or zip top freezer bags. Make sure to leave some headspace at the top since liquids expand when frozen. Then seal and freeze for up to 6 months.
How to Thaw Frozen Simple Syrup
Thaw frozen simple syrup overnight in the fridge. You can also thaw it at room temperature for a few hours. Give it a good stir once thawed and liquefied. The consistency may be slightly different after thawing, but the syrup will still taste delicious.
Tips for Making Simple Syrup Last
Follow these tips to maximize the shelf life of your simple syrup:
- Use clean containers – Make sure whatever container you store the syrup in is super clean and sanitized to prevent bacteria growth.
- Cool completely before storing – Let the simple syrup cool to room temperature before putting it in the fridge or freezer so it chills faster.
- Leave headspace – Don’t fill containers to the very top. Leave a little room for the liquid to expand as it freezes.
- Use within recommended time – Toss refrigerated syrup after 1 month and frozen after 6 months for best quality.
How to Tell if Simple Syrup Has Gone Bad
Here are some signs that your simple syrup has spoiled and needs to be thrown out:
- Mold growing inside the jar
- Cloudy appearance instead of clear
- Strange smells like fermentation or rotten eggs
- Sour or off taste
If you see any of those signs, err on the side of caution and get rid of the syrup. Mold spores and bacteria can spread quickly to contaminate other food.
Other Ways to Preserve Simple Syrup
While refrigerating and freezing are the two most common methods, there are a couple other ways you can try preserving simple syrup for longer duration:
Canning Simple Syrup
Because of its high sugar content, simple syrup is acidic enough to be safely canned using a water bath canner. This allows it to be shelf-stable at room temperature for up to a year. Follow proper canning procedures carefully to prevent any foodborne illnesses.
Adding Preservatives
You can add a small amount of preservative like potassium sorbate to make simple syrup last 2-3 months at room temperature. Add 1/4 teaspoon potassium sorbate per cup of syrup. This stops mold and fermentation.
Conclusion
With proper storage methods like refrigeration and freezing, simple syrup can last for months beyond its normal shelf life. For the longest duration, freeze syrup in airtight containers for up to 6 months. And refrigeration keeps syrup fresh for 1 month. With just some sugar, water, and a little planning, you can enjoy simple syrup any time a recipe calls for it.
