The Benefits of Refrigerating Pickles
Some styles of pickle preparation can go without refrigeration depending on whether the jar is already open.
However, in almost all cases, refrigeration is beneficial, especially if you won’t be consuming your pickles for a while.
The benefits of refrigerating pickles include:
- Maintains firm texture
- Keeps its pleasant aroma
- Preserves its flavor
Do Pickles Have to be Refrigerated After Opening?
You should always refrigerate your pickles after opening them. To do so, leave your pickles in the jar they came in and ensure you seal the lid tightly. Alternatively, you can transfer them into another airtight container.
The exception to this are fermented pickles that come in barrels. These pickles don’t need refrigeration, and they contain more gut-healthy bacteria . However, they have a much shorter shelf-life (usually up to a few months) since the fermentation process never ends.
In contrast, store-bought jarred pickles almost always undergo pasteurization. That puts a stop to the fermentation process. As a result, these pickles have a much longer shelf life without refrigeration.
Determining Whether to Refrigerate Pickles
When you buy a jar of pickles from the grocery store, the best option is to follow their storage method.
Most of the time, you’ll encounter pickle jars in the canned, non-refrigerated section of a supermarket. But sometimes, they put pickles in the refrigerator section. In that case, you can assume the company didn’t pasteurize the refrigerated pickles.
In either case, once you open your can of pickles, it’s best practice to keep them refrigerated so that you extend their shelf life.
Optimal Conditions for Non-refrigerated Pickles
Although it’s okay to store many types of pickles on a shelf, you need to ensure they have the right conditions to maximize their shelf life.
The ideal shelf conditions for pickles include:
- Temperature between 30 – 50 degrees Fahrenheit
- No direct contact with sunlight
- Humidity between 80 – 90%
Of course, you also need to ensure that your pickle jars have tightly sealed lids. Otherwise, air and bacteria will enter, spoiling your pickles.
How to Store Pickles
Now that you know the answer to the question, “Do pickles need to be refrigerated?” let’s examine the three ways you can purchase and store pickles.
Pickles in Jars
Storing pickles in jars is the most common way to keep them.
Whether you make pickles at home or purchase them from the grocery store, glass jars are the go-to method.
As long as a pickle jar has a tight seal, you can expect it to have a long shelf life before you open it without refrigeration.
That said, you can’t expect to store your pickle jars in 80-degree weather without it impacting them when you go to use them a year later.
So, you should keep unrefrigerated pickle jars at temperatures of no higher than 50 degrees Fahrenheit.
Pickles have a long shelf life in jars. But if you have more jars than you can consume, freezing them is a great option.
Before you freeze your pickles, make sure you know how you’ll use them when you defrost them. That’s because frozen pickles lose their crunch, so it’s best to include them in hot dishes where their texture isn’t as important.
You’ll need to put a little legwork into freezing pickles, as you’ll first need to drain the brine and dry the pickles as well as possible. Then place them in freezer bags.
If you don’t want the pickles sticking together, you can flash freeze them by spreading them out on a cookie sheet and placing them in the freezer for about 20 minutes before bagging them.
Pickles in Barrels
Storing pickles in barrels dates back to the late 1800s  when Jewish immigrants brought kosher dill pickles to the United States.
Jews would push carts of pickles across the streets in New York City. They became such a hit that today you can still encounter many Jewish delis serving pickles from barrels.
Pickles in barrels don’t last nearly as long as jarred pickles because the fermentation process doesn’t stop. The lifespan of pickles from barrels is about a few months. At that point, the pickles take on a strong, sour taste.
If you eat pickles from a barrel, you’ll also notice that they have a softer texture, especially the older the pickle gets. The fermentation process also causes them to develop mucus.
How to Tell if Your Pickles Went Bad
Since jarred pickles have such a long shelf life, you might wonder if they have an eternal shelf life like honey .
So, do pickles go bad?
Yes, they do.
Luckily, it’s easy to tell if you have a bad jar of pickles on your hands. Signs to look for include:
- Cloudy brine
- Slimy appearance
- Rancid smell
- Bulging lid
- Bitter taste
You also might notice that pickles sticking up out of the brine have mold on them. However, this isn’t necessarily an indication that your pickles are bad. Instead, that’s a natural reaction when pickles mix with air.
So, if you notice a moldy top of a pickle but you don’t see any of the other signs listed here that your pickles are bad, feel free to throw out the moldy pickle and enjoy munching on the rest of the non-moldy ones in the jar.
