Does homemade simple syrup need to be refrigerated?

Yes, homemade simple syrup should be refrigerated. Because it contains no preservatives, keeping it cold drastically slows down mold and bacteria growth.

What happens if you don't refrigerate simple syrup?

If you don't refrigerate simple syrup, it will spoil and ferment much faster. Because it is water-based and contains no preservatives, an unrefrigerated 1:1 simple syrup will typically only last for 1 to 2 weeks before developing mold, cloudiness, or a sour smell.

How to make homemade simple syrup shelf stable?

To make homemade simple syrup shelf-stable for 6 months or more, increase the sugar-to-water ratio to 2:1 (Rich Simple Syrup). The high sugar concentration prevents bacteria growth. Alternatively, sterilize your glass bottles before pouring, or add 1 tablespoon of vodka per 2 cups of syrup.

How long will simple syrup last out of the fridge?

Unrefrigerated simple syrup lasts about 1 to 2 weeks for a standard 1:1 ratio, and up to 1 month for a rich 2:1 ratio (2 parts sugar to 1 part water).

How to avoid mold in homemade simple syrup?

Can botulism grow in sugar syrup?

Due to their low water activity, dehydrated foods and foods high in salt and/or sugar do not support growth of C. botulinum. Some strains of C. botulinum can be mesophilic, with an ideal growth temperature between 68°F–113°F (20°C–45°C), whereas others are psychotropic, with ideal growth between 38°F–60°F (3°C–20°C).

How can I tell if my simple syrup has gone bad?

To tell if simple syrup is bad, check for cloudiness, visible mold, floaters, or a sour/fermented smell. Unlike pure sugar, the water content makes it prone to spoilage. Always discard the syrup if you notice any of these visual or scent indicators.

How to store simple syrup for cocktails?

Store simple syrup in an airtight glass container, like a mason jar or a swing-top bottle. Always keep it in the refrigerator to prevent mold and bacterial growth. Standard 1:1 syrup lasts about 3 to 4 weeks, while "rich" 2:1 syrup lasts up to 6 months.

What is the 86 rule for maple syrup?

The Jones “Rule of 86” was devised in 1946 by C.H. Jones, a scientist and educator at the University of Vermont. The gist of the rule is that ifone divides 86 by the sugar content of sap, you can estimate the amount of sap required to produce a gallon of syrup.

What is the best preservative for simple syrup?

Simple syrup can be preserved for months by adding 1 ounce of sodium benzoate with ¼ ounce of citric acid, per gallon of simple syrup. Each ingredient must be added separately and stirred into the syrup separately and thoroughly.

Can you make simple syrup ahead of time?

The Risks of Not Refrigerating

If you decide to leave your syrup out after opening, you'll likely notice changes in the syrup's appearance, smell, and taste after a short time. Without refrigeration, the sugar-water mixture is prone to fermentation, leading to spoilage.

What kind of sugar is best for simple syrup?

For a traditional, neutral simple syrup, standard white granulated sugar or pure cane sugar is the absolute best. It dissolves completely, stays clear, and provides pure sweetness without altering the flavor of your coffee, tea, or cocktails.

What is the best container for simple syrup?

The best container for simple syrup is an airtight glass bottle or jar, which prevents the syrup from taking on plastic odors. For quick pouring and easy portioning, narrow-necked Boston round bottles, flip-top Grolsch-style bottles, or professional-grade syrup bottles (like the Crew Supply Co. Chubby Bottle) work best.

Is simple syrup ok if not refrigerated?

You can leave simple syrup out of the fridge, but only if you are using it within a few days or if it is a "rich" 2:1 ratio. Standard 1:1 simple syrup spoils quickly at room temperature.

In our experience, heat-resistant mold spores (ascospores) can be present in liquid sucrose and high fructose corn syrup and can contribute to the spoilage of beverages where these sweeteners are used.
