What is simple syrup?
Simple syrup is a mixture of equal parts sugar and water that is heated together until the sugar dissolves. It is used to sweeten drinks like coffee, tea, cocktails and more. The most common ratio is 1:1, meaning 1 cup of sugar dissolved in 1 cup of water. However, simple syrup can be made in any ratio desired.
Simple syrup is a handy ingredient to have on hand because the sugar is already dissolved, making it easy to incorporate into both hot and cold beverages. It mixes in more evenly than just adding granulated sugar. Simple syrup is clear in color and has a thick, viscous consistency. It delivers sweetness without altering the flavors in drinks.
Does simple syrup go bad?
Yes, simple syrup can go bad eventually if not stored properly. Simple syrup is very high in moisture content because of the water used to dissolve the sugar. This moisture provides an environment where mold, bacteria and yeast can potentially grow. Simple syrup also does not contain any preservatives to prevent microbial growth.
However, simple syrup can last for a surprisingly long time in the refrigerator if stored in an airtight container. The refrigerator temperature helps retard any microbial growth. Over time though, the syrup may start to crystallize, change color, develop mold or smell bad indicating spoilage.
How long does simple syrup last in the fridge?
Properly stored simple syrup will generally last 2-4 weeks in the refrigerator according to most sources. Here are some tips for maximizing the shelf life of simple syrup:
– Use sterile bottles or containers. Make sure containers are super clean before filling with simple syrup.
– Fill containers all the way to the top to minimize excess air. Air can promote mold growth.
– Use airtight, sealed containers like mason jars or bottles with tight lidding. This prevents contamination.
– Store in refrigerator immediately after making and cooling the syrup. Don’t let it sit out.
– Make smaller batches instead of large batches to use up quicker.
– Use clean utensils and cookware when making simple syrup. Don’t introduce bacteria.
– Check regularly for any signs of mold, crystallization, fermentation or color changes.
Following these steps, most simple syrups can last up to a month in the fridge before quality starts to decline. Some factors like ingredient quality and refrigerator temperature can impact shelf life as well. For example, if the fridge runs warmer, syrup may not last as long.
How to tell if simple syrup has gone bad?
Here are some signs that indicate simple syrup has spoiled and should be discarded:
– Mold growth – You may see fuzzy mold growing either on the surface or below the syrup. Mold will start out in small colonies at first. Discard immediately if any mold is found.
– Fermentation – Simple syrup may start to ferment with the sugars breaking down. You may see bubbling, taste a distinct alcohol flavor or smell yeastiness.
– Changes in texture – As simple syrup ages, the liquid may become more viscous, thick and gloppy. It could also crystallize with sugar grains forming.
– Changes in color – Fresh simple syrup is clear and colorless. As it spoils, it may darken and become cloudy or yellow.
– Off smells – Simple syrup that has gone bad may smell rotten, vinegary or unpleasant. It may smell distinctly less sweet.
-Odd tastes – A spoiled simple syrup may taste tangy, bitter, or just clearly not as sweet as it originally was.
If you detect any of these traits in an older simple syrup, it’s best to just throw it out and start fresh rather than risk getting sick from contamination. Simple syrup is easy and inexpensive to make, so it’s not worth trying to salvage a batch that has clearly turned. When in doubt, pour it out.
Does simple syrup need to be refrigerated?
Simple syrup will last longer in the refrigerator than at room temperature. Refrigeration is the best storage method for simple syrup to maximize its shelf life. Simple syrup contains high amounts of moisture, which microbes can thrive on if left unrefrigerated.
Room temperature conditions allow mold, yeast and bacteria to grow much more quickly in simple syrup. While sugar itself has some antimicrobial abilities, over time simple syrup left out can still degrade in quality and become unsafe to consume.
For short term storage of up to a week, simple syrup can be left out sealed at room temperature. However, for any longer term storage, proper refrigeration is recommended. Once cooled after making, syrup should be immediately put into the refrigerator.
Can you freeze simple syrup?
Yes, simple syrup can be frozen for longer term storage. Freezing stops any microbial growth and keeps the syrup preserved longer than the refrigerator.
To freeze simple syrup:
– Let prepared simple syrup cool completely first.
– Pour into freezer-safe containers leaving about 1/2 inch headspace. Mason jars or freezer bags work well.
– Seal the containers airtight. This prevents freezer burn or introduction of odors.
– Label the containers with the date.
– Store in freezer up to 3-6 months.
Simple syrup may crystallize and harden in the freezer as the sugars freeze into ice crystals. Thaw completely in the refrigerator before using again.
Once thawed, simple syrup can be used just like fresh simple syrup. Give it a stir or shake when thawed to reincorporate any separated water.
Freezing is a great way to make bigger batches of simple syrup ahead of time to have on hand for iced coffee, cocktail mixing and baking needs.
Can you freeze simple syrup in ice cube trays?
Yes, freezing simple syrup in ice cube trays is an easy way to portion out tablespoon-sized amounts of syrup to grab from the freezer as needed.
To freeze simple syrup into ice cubes:
– Make a batch of simple syrup and let cool completely after boiling.
– Pour carefully into ice cube tray compartments.
– Cover the tray and place in freezer overnight or until solidly frozen.
– Pop out the simple syrup cubes. Store them in a freezer bag.
The simple syrup ice cubes can be dropped directly into drinks, coffees or teas to sweeten with easy, pre-measured portions. They store well in the freezer for months and thaw quickly when needed.
Freezing simple syrup into ice cube trays makes for ready-to-use sweetener drops whenever a recipe calls for just a tablespoon or two of syrup. No need to thaw a whole batch.
Does simple syrup need to be refrigerated after opening?
Once opened, simple syrup should always be refrigerated. Unused portion leftover after opening the syrup should be promptly stored in the refrigerator in an airtight container.
Even though syrup was kept refrigerated initially after first being prepared, once exposed to air by opening, the syrup is vulnerable to potential contamination from bacteria, yeast, mold and other microbes. Refrigeration inhibits microbial growth.
Therefore, promptly refrigerating opened simple syrup is important for food safety. Only keep at room temperature the portion being actively used. Screw lids on tightly and return containers to the refrigerator as soon as possible after opening.
Check refrigerated opened syrup periodically for any signs of spoilage like mold, sliminess, yeast bubbles or an unpleasant smell. Discard if any deterioration is noticed. For optimal quality and freshness, use up opened simple syrup within 2-4 weeks.
Can you refrigerate simple syrup in a jar?
Yes, canning jars are an ideal way to store simple syrup in the refrigerator. Wide mouth mason jars provide a number of advantages:
– Allows for easy pouring of viscous syrup.
– Creates an airtight seal to prevent contamination.
– Can be sterilized by boiling before use for clean storage.
– Allows visibility of syrup’s color and texture.
– Long lasting and reusable.
When refrigerating simple syrup in a mason jar:
– Fill jar all the way to the top to minimize air exposure.
– Ensure lid is sealed tightly.
– Store towards the back of the fridge where temperature is coldest.
– Use within 1 month for best quality.
– Clean and sanitize jars properly before reusing.
Jars are an inexpensive, readily available option for keeping simple syrup fresh in the fridge. Just be sure to label jars with date of preparation.
What’s the best container for simple syrup storage?
The best containers for storing simple syrup are:
– Glass Mason Jars – Durable, nonporous and reusable. Allows you to see syrup contents.
– Plastic Food Storage Containers – Affordable and lightweight. Some may stain over time with syrup.
– Bottles with Tight Lids – Liquor bottles, glass condiment bottles, etc seal tightly. Convenient for pouring.
– Squeeze Bottles – Great for drizzling syrup easily. Need to be washed well.
– Metal Tins – Sturdy and provide complete light blockage. Can react with acidic ingredients.
Look for containers that are clean, airtight, durable, moisture-proof and ideally made of nonreactive materials like glass or stainless steel. Avoid porous materials like untreated wood. Reuse any food-safe containers as needed.
No matter what type of container used, the keys are to sanitize it first, fill syrup all the way to the top and seal it completely airtight. This prevents contamination and maximizes shelf life in the refrigerator or freezer. Label containers clearly as well with syrup variety and date prepared.
Does simple syrup get moldy?
Yes, simple syrup can get moldy if left out too long at room temperature or improperly stored after opening. The high moisture content of simple syrup makes it vulnerable to mold growth when exposed to air.
Mold requires moisture, warmth and air to thrive. Simple syrup inherently provides the ample moisture mold loves. If kept constantly refrigerated in airtight containers, simple syrup denies mold the other factors it needs. But simple syrup left out or reopened and stored at room temp can absolutely grow mold over time.
You may see fuzzy mold colonies begin forming either on the surface or suspended within the syrup. Discard immediately if any mold is evident. Mold spores spread rapidly and can’t be salvaged once present. Never scoop mold off and use syrup underneath.
To avoid moldy simple syrup:
– Refrigerate promptly after making
– Use clean containers
– Fill containers all the way
– Seal airtight
– Don’t double dip dirty utensils
– Watch for bubbling, sliminess or fuzziness
With proper refrigerated storage in sealed containers, mold growth can be prevented in homemade simple syrup.
What does moldy simple syrup look like?
Here’s what to look for to identify moldy simple syrup:
Fuzzy Growth – You may see cottony or hairy mold colonies on the surface of the syrup or floating within it. Mold comes in many colors like black, white, blue, green or grey. It may start out as tiny dots that enlarge into larger circular clumps.
Bubbles – Mold growth inside syrup often produces air pockets and bubbles as the mold ferments. You may see strings of tiny dots extending through syrup.
Sliminess – As mold feeds on syrup, it can cause a change in texture, making the liquid feel slippery or slimy.
Discoloration – Simple syrup may darken, turn cloudy or develop a yellowish hue if mold is present.
Separation – Liquid and sugars may separate with mold growth, resulting in a layer of darker syrup on the bottom.
Smell – Moldy simple syrup may start to smell rotten, musty or unpleasant instead of sweet.
If you notice any of these warning signs, don’t taste the syrup! Simply discard it and make a new clean batch. Mold spores contaminate quickly and can’t be eradicated once present.
How do you keep simple syrup from molding?
Here are some tips for preventing mold growth in homemade simple syrup:
– Use sterilized containers and utensils – Clean thoroughly to destroy any lingering bacteria. Consider boiling jars before use.
– Fill containers all the way – Leave as little headspace as possible to minimize air and oxygen mold needs.
– Seal airtight – Use bottles or jars with tight fitting lids to block air exposure.
– Refrigerate immediately – Don’t let cool before storing in fridge.
– Freeze for long term – Freezing stops mold growth for months.
– Rotate stock – Use older syrup first. Don’t let batches sit too long.
– Add preservatives – Try adding lemon juice or vodka to lower pH and inhibit mold.
– Avoid double dipping – Use clean utensils each time to prevent contamination.
– Watch for warning signs – Discard at first sign of mold like smell, bubbles or sliminess.
With proper sanitation, prompt refrigeration and air-tight storage containers, it’s easy to keep simple syrup mold-free for weeks at a time.
Can you make simple syrup with vodka to prevent mold?
Yes, you can make a simple syrup with vodka added to help extend its shelf life and prevent mold growth. The alcohol in vodka acts as a preservative.
Here is a basic recipe for vodka simple syrup:
Ingredients:
– 1 cup sugar
– 1 cup water
– 1-2 ounces vodka (1-2 shots)
Instructions:
1. Combine the sugar and water in a small saucepan. Heat over medium, stirring frequently, until sugar dissolves.
2. Remove from heat and let cool for 15 minutes.
3. Stir in vodka.
4. Transfer to an airtight container and refrigerate.
The vodka inhibits microbial growth while allowing the syrup flavors to come through. Start with 1 ounce vodka and add more as desired. Too much vodka can make the syrup overly boozy.
With the vodka, the simple syrup keeps longer up to 6 weeks refrigerated. Make sure to use clean utensils and containers each time to prevent cross contamination when using.
Conclusion
Simple syrup has an inherently short shelf life due to its high moisture content and lack of preservatives. However, with proper refrigeration and storage methods, most simple syrups can last 2-4 weeks before quality starts to decline.
Look for signs of mold growth, fermentation, changes in color or texture, or unpleasant smells which indicate simple syrup has spoiled and should be discarded. Refrigerating promptly after making, minimizing air exposure, and using clean containers help maximize freshness. For long term storage up to 6 months, simple syrup can be frozen for later use.
Preventing mold growth is key to keeping simple syrup safe to consume. With vigilance of refrigeration and storage conditions, it’s possible to keep homemade simple syrup from going bad for a reasonable timeframe. Follow proper handling procedures and simple syrup can remain a convenient sweeter for drinks, baking and more.
