Do You Refrigerate Molasses After Opening? (most important facts revealed)

FYI: Molasses is a thick syrup derived from pure sugar cane juice (learn something new every day).


This syrup has a light to deep brown color and a distinct flavor. Molasses is used in cooking, baking, and grilling. It can be added to sauces and marinades too. But enough about that…


Do You Refrigerate Molasses After Opening?

Unopened jars of molasses can last a year in a cool, dry, dark environment. Refrigerating molasses helps maintain a consistent temperature, which is advantageous in hotter climates.


After conducting additional research, I discovered additional information that you should be aware of, so please continue reading…



What is the shelf life of molasses?

A byproduct of the sugar-making process, molasses is formed from crushed sugar cane or sugar beets. It is used to sweeten coffee and tea.


There are many distinct variations of this thick syrup, each having a different color and consistency as well as a varied taste and sugar concentration.


Molasses Expiration Dates and Shelf Life:


  • Blackstrap molasses is the thickest and darkest of the molasses varieties, and it is the most often used. It should keep in the cupboard for at least a year and maybe up to two years if left unopened.

  • The product should be used within six months after being opened.

  • It is lighter in color and thickness than blackstrap, but it has the same shelf life of one to two years when kept refrigerated and six months after opening when kept at room temperature.

  • Unsulfured molasses does not include the preservative sulfur dioxide, which helps to keep it from rotting. As a result, it will not survive as long as sulfured molasses under the same conditions. It’s ideal if you use it within six months of purchasing it, and you should keep it refrigerated rather than in the cabinet like other sorts after it’s opened.

The main variation in shelf life between opened and unopened bottles of molasses is the amount of time they have been opened…


A bottle of molasses that has not been opened will keep in the pantry for at least a year. In actuality, if it is kept correctly, it may survive for up to two years at the most.


Once the bottle is opened, the quality of the molasses begins to deteriorate, and the bottle will not last as long. To be on the safe side, molasses that has been opened should be consumed within six months after opening.


If you buy a bottle and keep it for one year before opening it, the bottle will last you for 18 months at the most.


It’s a good idea to write down the date of purchase and the date of opening on the molasses package so that you can be certain that the bottle is the correct age.


In most cases, there will be a “best before” or “use by” date on the bottle, which is only a recommendation…


If the molasses does not exhibit any indications of spoilage, it might potentially persist for up to four years if it is kept in the appropriate manner.



How to Tell if Molasses Is Bad

To get a sense of what your molasses will look and taste like when it’s in optimal condition, it’s a good idea to look at it and taste it when you first open the container.


Then you can keep an eye out for symptoms that it’s starting to go bad. In order to detect those telltale symptoms before the food has entirely gone bad, undertake a three-part test, paying attention to how it looks, how it smells, and how it tastes before consuming it. The first test is to see what it looks like when you first open it.


Here are a few indicators that it should be discarded immediately:


  • A moldy top or surface of the molasses may be found on the bottle.

  • There is evidence of crystallization or clumping in the material.

  • There has been a shift in hue or in some other aspect of appearance.

If the bottle seems to be in good condition but the fragrance is off, it is better to replace it. Unless the stench is terrible, you’ll be able to tell right away that it’s no longer any good.

If the appearance and scent are satisfactory, but you are still unsure if it is safe to consume, you might try tasting a little spoonful of it. Taking a modest quantity shouldn’t make you sick, and you will be able to determine whether or not it is safe to continue taking.


Molasses Storage Instructions

elements affecting molasses’ shelf life, keeping the product fresh and stable for an extended period of time is simple.


Simply store the product in a cool, dry location. Because it is OK to store it at room temperature, a covered closet or pantry is an excellent alternative for storage.


If at all feasible, keeping it in the basement or cellar is preferable since it will be out of the way of the heat and humidity that may penetrate a kitchen.


It is critical to ensure that, after the lid has been opened, it is firmly closed at the end of each usage. You may quickly ruin your molasses if you store it with the lid off if the container is not well sealed.


Related Questions

1. Is it necessary to keep molasses refrigerated?


You do not need to refrigerate molasses, with the exception of unsulfured molasses. Because it has the potential to ferment, it should be kept refrigerated unless you want to consume it fast. Regular molasses would become quite thick and difficult to pour if kept in the refrigerator. 

2. Is It Possible to Freeze Molasses?


While it is feasible to keep molasses in the freezer, it is unlikely to freeze solid due to the presence of sugar in the mixture. When it is thawed, it will most likely be grainy or crystalline, similar to how honey becomes grainy or crystallized.


3. Is it possible to become sick from spoiled molasses?


If you have any worries regarding the freshness of an item, such as molasses, it is preferable to discard it. It’s far simpler to just purchase a new jar rather than to be concerned about any potential unwanted effects. It’s also worth noting that molasses becomes more difficult to pour or utilize in cooking when it becomes excessively thick or crystallizes.


4. What to do with molasses that has gone bad?


You may use it to sweeten coffee, waffle or pancake batters, smoothies, shakes, applesauce, or a warm glass of milk. It can also be used to sweeten smoothies and shakes.


5. Is it possible to become ill from molasses?


If you have any worries regarding the freshness of an item, such as molasses, it is preferable to discard it. When molasses becomes excessively thick or crystallizes, it becomes more difficult to pour or use in cooking, making it less convenient.

6. How to preserve molasses for an extended period of time?


Jars of molasses that have not been opened should be kept in a cold, dry, dark place where they will stay for up to one year. The most serious risks to molasses are heat and humidity, both of which may cause bacteria to multiply and form mold.


Final Thoughts

So, class, what did we learn? Unopened molasses jars should be stored in a cool, dry, dark area for up to a year. Molasses may be refrigerated, although it is not required.


Refrigeration helps keep a constant temperature, which is good for molasses, especially in hotter climates. The time taken to open a bottle of molasses determines its shelf life.


Unopened molasses will keep for a year in the pantry. In reality, if properly stored, it may last up to two years. Once opened, the molasses quality degrades and the bottle does not last as long.


To be safe, molasses should be eaten within six months after opening. If you purchase a bottle and store it for a year, it will last you at most 18 months.


On the molasses box, mark the date of purchase and the date of opening to ensure the bottle is the right age. Enjoy the rest of your day, always stay safe, and treat others with kindness and respect. Until next time!
