Does Syrup Go Bad

Does Syrup Go Bad

The best thing you can do is to try the maple syrup — you will immediately know whether or not you want to use that cup of maple syrup you have been saving in your basement for 5 years, or you would rather just throw it out.

One thing people do agree on is that maple syrup does not spoil or get worse if stored correctly, so as long as you are not going to store it with its lid off, it is going to be edible a year from now, and maybe a couple years. Plastic containers will not keep it as long, and cans will provide even shorter shelf lives. If stored in a sealed glass bottle, maple syrup should last about four years, maybe more; if stored in a plastic container, as much as two years; and if stored in a tin or can, only about six months. For a bottle of maple syrup that has been opened and used, it will keep fine for a year to a few years, provided that it is kept refrigerated consistently.

If you suspect that you are going to hang on to your maple syrup longer than about six months, you are better off keeping it in your freezer–yes, this is really something you can do–where it will be safe for the rest of time. An unopened bottle of maple syrup can also be stored at room temperature indefinitely, provided that you are careful to keep it in a cool, dry location, out of direct sunlight, with the lid closed tight, and that the package is not damaged. In the event that you do not have an open lid, you can keep maple syrup in a cooler for added protection, since cold temperatures will keep mold from growing inside the syrup bottles. If your syrup does grow mold after being exposed to extreme temperatures, you would be best off throwing it away and getting a new bottle.

If you are in any doubt as to whether there is mold, or if you are not keen on taking any chances, dispose of your moldy syrup and buy a new bottle. If you spot mold growth, you can skim off and boil off the remaining syrup for safe keeping. When you see any mold growing on the top surface of your syrup, you can just skim off the top and boil the syrup. If you skim off the moldy bits, you will still be able to use your syrup for the pancakes, as mold is a different kind of mildew from the ones we are used to seeing in fresh fruits.

Some folks argue for skimming the mold and still using plain old sugar syrup, but I think that is just faulty chemistry, and will only make whatever you are adding it to less desirable. Store-bought simple syrup does not recommend storing it in the fridge, but it will keep it fresher and will have been chilled fresh for your drinks. Unopened simple syrup has a longer shelf life, and although you should rely on its expiration date to stay fresh, it is likely to last well beyond that date. The quality of an unopened bottle of syrup may diminish over time, and even taste can change, but it does not get worse when stored properly.

Storing syrup right keeps the quality of the syrup for a long time, so while syrup for pancakes is resistant to most conditions, there is one particular way to store syrup. If you store Aunt Jemima syrup correctly, in a cool, dark corner of your pantry, and avoid any cross-contamination with other foods, you will keep the quality from dropping. No matter where you get syrup, as long as it is not packaged warm (above 180degF) but not hot (your authors recommend below 195degF) and put in a clean container, none of the best practices recommended here will keep you from wasting it.

It is always best to use simple syrup within one or two months of opening a can, keep sealed, and check every time you intend to use it for signs of spoilage. Your authors also suggest that you put the remaining syrup in a mason jar of glass of some kind, a one you have cleaned and disinfected beforehand (boiling it in water works well, just remember the lid!).

I will close with an extra note, while pasteurizing your syrup, try and avoid boiling it, because this will cause minerals suspended in the syrup to precipitate out, turning your syrup slightly cloudy (also called nightingale). Do not keep additives in this syrup long-term; simply steep for a bit and strain before storage.

Water may condense and evaporate in the container, changing the percentage diluted of the syrup. If your syrup is crystallizing, that is because extra water might have evaporated, which concentrated the sugars enough so there is more that could dissolve.

Also, syrups go through boiling, which significantly decreases syrups water content. According to Arnold Koombs, from Bascom Maple Farms, syrup hits 219degF (sugar increases water boiling temperature) and heat further sterilizes it. Often left in holding tanks until it is bottled, it is then strained out and re-heated to at least 180deg, the temperature which disinfects containers when poured into them.

If you notice your syrup is cloudy, or has a slight deposit at the bottom, it is just because it might have been unfiltered. If you see sediment (or crystals) at the bottom of the syrup bottle, it is not a sign of spoilage, nor is that residue dangerous.

If you keep your maple syrup container in your pantry and do not regularly inspect it, open maple syrup can spoil quickly due to moisture, high heat, and mould growth. Fortunately, it is an extremely rare event that maple syrup goes bad, and if you have not allowed any contaminants to enter your jar with the maple syrup, you should be good to go for a very long time. As is obvious from the last section, the easy answer is yes, you should definitely refrigerate your syrup, especially once opened.

How long does syrup last after opening?

All maple syrup can be kept in the cupboard for about a year before being consumed. Genuine maple syrup should be refrigerated after being opened and has a shelf life of roughly a year. Imitation maple syrup containers can be kept open for about a year in the cupboard.

Does syrup go bad after opening?

As it turns out, syrup actually has a pretty long shelf life. Most types of syrup can last for months or even years after opening. However, over time, the syrup will start to lose its flavor and become more watery. So if you’re using syrup that’s been sitting in your pantry for a while, discard them.

Does unopened syrup go bad?

While unopened syrup does not go bad, it can begin to degrade after a period of time. This is because the sweetener in syrup can start to crystallize, which can affect the flavor and texture of the syrup. If you notice that your unopened syrup is starting to crystallize, you can place it in the fridge to help slow down the process.
