Since pickles predate refrigeration by about 4000 years, you obviously do not have to store your pickles in the fridge once they are opened. Bacteria will start growing in them later, so you must, of course, refrigerate pickles after opening at all times. Having to refrigerate all your pickles after opening is one thing, but there are some types of pickles that you just need to refrigerate at all times, even if sealed. You should be reminded, too, that you have to refrigerate each type of pickle after you open it.
This is also the reason you should always store those pickles in refrigerated sections, regardless if you opened them or not. You should always keep the pickles in a refrigerator once you have opened your pickles, but a non-opened jar of pasteurized pickles does not need to be refrigerated, as they are just made this way. Because of the differences between these two types of pickle preservation, you may find pasteurized pickles in the canned foods aisle, and the unpasteurized ones in the refrigerated aisle.
Once opened, the pickles stay fresh for about the same amount of time, provided that they are stored in the fridge in tightly sealed containers. Even if these pickles are cooked, they will keep fresher for longer if you store them in the fridge once opened, rather than leaving them out at room temperature. Homemade pickles also retain their freshness and flavors longer if you keep them refrigerated. Pickles stored in a cooler often lose their crunch more quickly than those stored outdoors.

Opened, unpasteurized pickles can keep 3 months or longer if kept refrigerated at or below 40 degrees F. Even after opening, if you store your pasteurized or unpasteurized pickles in a sealed container, they last for an extended period of time.
If you leave the fridge door open and let pickles sit outside for several hours, the enzymes will start breaking the pickles down, and the pickles will lose their crunch. If you leave them in the fridge for a longer time, they will lose their crispness and taste.
An opened pickle jar can last in the fridge for nearly a month without losing its quality. Unopened, you can store a jar of pickles without refrigeration for up to two years, or until the shelf life date on the label. Store pasteurized, unopened pickles at room temperature in a cool, dark place for up to two years, but transfer the unopened to a refrigerator once opened. Unopened, fermented pickles can be stored at room temperature in a cool, dark place (like your pantry or pantry), but after opening, we will keep them in the fridge.
Pickled pickles, or those made using a pickling process instead of fermentation, can be kept up to two years past their expiration date, provided they are kept refrigerated. Unopened pickle jars do not require refrigeration, and may last for up to two years past expiration, provided they are stored in a consistently cool, dry location. We always recommend keeping opened products in a refrigerator to help slow the bacterial growth, but due to their high acid content and sealed jars, unopened pickles can be stored for years at room temperature. Pickles purchased unopened and not refrigerated may be stored in a dark, cool area, without refrigeration.
Keeping pickles may be an elaborate endeavor, as while they generally do not spoil at room temperature, in some cases you need refrigeration. To slow the fermentation process and preserve good flavors, it is necessary to store pickles refrigerated at home as well. Once the pickles reach your desired level of acidity, move them into the fridge to help them slowly ferment.
Once you have opened the pickle bottle, you are encouraged to store them refrigerated so that they retain their freshness and taste over time. While you can eat your way through the bottle before they begin to visibly deteriorate, you should always refrigerate your opened pickle can. Once you have opened your jar of pickles, you are encouraged to keep them tightly covered with their cap in a refrigerator that is set to at least 40 degrees F.

In case of home-made pickles, it is also recommended to store it in the fridge at or below 40 degrees Fahrenheit. The optimal temperature to store pickles is considered to be 32degF…34degF, and this is only possible by refrigerating them.
When you store pickles, pasteurized or not, in a refrigerator, shelf life is almost exactly the same as when you keep them at room temperature. Fermented pickled products are not supposed to be kept at room temperature, but if you do, they should still be able to keep quite a while.
Unfortunately, pasteurization destroys all of the bacteria in pickled vegetables, meaning that even if left at room temperature, they have trouble spoiling. If you do not store them in a refrigerator, then your pickles will begin spoiling very quickly, as they can get contaminated very easily once opened. Both methods for making pickles have their pros and cons, but one thing is obvious: They both require you to refrigerate any opened cans in order to prevent pickles from spoiling quickly. To prevent the pickled cucumbers from rotting, you can keep them in smaller jars in order to limit your opening times.
Opened pickles will have good flavor for 1-2 months, provided they are kept refrigerated, but they are probably still pretty good for eating another month or two. Pickles are particularly tough, however, and are likely to remain fresh in both your pantry and your refrigerator for a year or two after their best-by date, provided they are sealed correctly, experts from Healthy Canning tell us. Pickles left outside for more than two hours (including at night) should be thrown away, according to USDAs official guidelines for all foods that need refrigeration.
Do Vlasic pickles have to be refrigerated after opening?
No, they do not need to be refrigerated if they come in a jar or can because they contain very little moisture. Vlasic pickles, on the other hand, must be refrigerated after opening. Because they contain vinegar and other preservatives, they will spoil if left out of the refrigerator.
How long do pickles last opened unrefrigerated?
Food safety experts agree that opened jars of pickles should be refrigerated to ensure maximum freshness and quality. Without refrigeration, opened pickles will only last for a few days before they start to spoil. If you’re looking to extend the shelf life of your opened pickles, refrigeration is the way to go.
Can pickles be left out overnight?
It turns out that leaving pickles out overnight is perfectly safe from a health perspective. The main risk is that the pickles will become sour and less edible. However, as long as you consume them within a few days, there is no need to worry. So there you have it – you can rest easy the next time you forget to put your pickles away.
