How Can You Tell if Sauerkraut Is Bad
Here's all y'all need to know about storage, shelf life, and going bad of sauerkraut. In this article, you will acquire how to tell if yours is bad and how long information technology will last.
In that location's a lot of conflicting information about sauerkraut on the Internet. Some argue that it lasts forever, while several producers recommend storing theirs for just a week later opening.
It's like shooting fish in a barrel to get dislocated. This article is my attempt to straighten things out.
To start, let's talk about the two types of sauerkraut bachelor. Knowing the differences betwixt the two will make everything else so much easier.
Unpasteurized vs. Pasteurized Sauerkraut
In that location are two kinds of sauerkraut bachelor on the market: unpasteurized and pasteurized.
The principal difference between the two is that the start one is raw and live, with a whole lot of probiotics, while the 2nd one is cooked, and most of the probiotics are expressionless.
And since the first one is live and the fermentation process is ongoing, it needs to be refrigerated then that information technology doesn't ferment too much and becomes too sour.
In pasteurized sauerkraut, the fermentation process has been stopped past applying heat, and because of that, in that location are no live bacteria. That ways that as long as the can or jar is unopened, there's no demand for refrigeration.
That's why you lot see some sauerkraut in the refrigerated section, while the residual sits on the shelves. The same logic applies to kombucha.

(Some products are in between. They aren't fully pasteurized simply don't crave refrigeration. Fortunately, most kraut out there is either i or the other.)
Tip
If yous purchase sauerkraut for its health benefits, choose the one that's sold refrigerated.
Knowing that in that location are two types of sauerkraut: unpasteurized (sold refrigerated) and pasteurized (shelf-stable), let's tackle spoilage, shelf life, and storage of both.
Does Sauerkraut Become Bad?
Pasteurized sauerkraut keeps only for a calendar week or then after opening and easily goes bad. Unpasteurized sauerkraut, on the other hand, tin can go on for months later on opening if you refrigerate it and continue it submerged in brine. It will gradually deteriorate in quality, however.
In other words, pasteurized sauerkraut can go bad quickly, while its unpasteurized counterpart doesn't, assuming that you store the kraut properly.
Of course, if you don't shop your unpasteurized sauerkraut properly, it tin can dry out or even grow mold fairly quickly. That's why it'southward important to accept skillful care of it.
(I cover storage in detail later in the article.)
At present, before we talk about signs of spoilage, let's cover a couple of things you might observe odd at outset but are perfectly normal for unpasteurized sauerkraut.
Note
Sometimes, instead of the word "pasteurized," the phrase "hot-packed" is used. It's essentially the same affair.
Things Unpasteurized Sauerkraut Does
As you already know, unpasteurized sauerkraut contains living organisms. That has several consequences.
Fizz and Bubbles
If your refrigerated sauerkraut is fizzy and bubbly after opening, that'due south normal. The ongoing fermentation causes a buildup of CO2 gas, which doesn't take anywhere to become because of the lid. Now that yous removed the chapeau, the CO2 buildup can be released, causing bubbles.
That's too why some brands put release valves on their packages.
(In case you were wondering, a similar affair happens to champagne.)
Bulged Lid
Same as in a higher place, the gas buildup tin can sometimes bulge the lid, and that's normal. It'south non a common occurrence, just don't panic if information technology happens to yous.
Difficulty Unscrewing the Lid
The last event of CO2 buildup in unpasteurized sauerkraut is that if it'due south jarred, the lid might be hard to get off.
Here are two things you can try to finally open that jar:
- Get out the jar at room temperature for 5 minutes. It might assist salve some of the pressure and allow yous in.
- Run the lid border under warm water for a few seconds. Aforementioned as above, nosotros apply temperature change to help release the force per unit area.
Taste Differs Betwixt Batches
Since refrigerated sauerkraut is a living thing, every batch is slightly different. So there'southward no need to be alarmed if this container tastes a chip different than the last i. Unfortunately, that's something that cannot exist controlled.
Now that you know what'southward okay for refrigerated kraut, allow's talk about signs of storage.
Warning
If your fermented cabbage is pasteurized and shows either of these signs, information technology's almost certainly bad. You might want to check with the FAQ section of the brand's website for confirmation.
How to Tell if Sauerkraut Is Bad?
Signs of spoiled sauerkraut include:
- Off odour. If information technology smells funny, off, or like information technology'due south rotting, it's obvious that sauerkraut has gone bad. Sauerkraut should olfactory property fermenty and fresh.
- Changes on the surface. If the alkali doesn't cover the leaves, a couple of things could happen. They might dry out out a bit, which isn't a problem. But if they're uncovered for more than than a couple of days, either white picture (photo below) or mold shows upwards. If your kraut is unpasteurized, y'all could, in theory, eat whatever is under the brine, merely I think discarding the fermented cabbage, in this example, is the way to become. Improve safety than sorry.
- Besides long storage time. If your kraut is pasteurized and open for more, say, two weeks, it's time for it to get. It doesn't go bad speedily because it'south usually brined with vinegar (which helps prevent bacteria from multiplying), but it doesn't last that long either. As for raw sauerkraut, go with whatsoever you're comfortable with fourth dimension-wise (more than on that after).
Finally, if everything seems to be fine, tasting the sauerkraut is the terminal step of the process.
Now, if it's the unpasteurized diversity, the thing is still alive and the fermentation is ongoing. That means the taste might change over time, and the cabbage might lose some of its crunch if it sits in the fridge for months. Be prepared for that.
Otherwise, get with your gut. If it notwithstanding tastes good and the storage time is reasonable, go for it.
How Long Does Sauerkraut Concluding?
| Pantry | Refrigerator | |
|---|---|---|
| Sauerkraut (unpasteurized, unopened) | Sell-by + 3+ months | |
| Sauerkraut (unpasteurized, open) | iv-6+ months | |
| Sauerkraut (pasteurized, unopened) | Best-by + 3-6 months | |
| Sauerkraut (pasteurized, open) | 5 – 7 days |
Unpasteurized sauerkraut can keep for 4 to 6 months after opening the container, or fifty-fifty longer. The quality will gradually degrade, but as long as the cabbage is covered in brine, it volition stay safe to swallow.
Pasteurized sauerkraut, on the other hand, ordinarily keeps for about vii to 10 days of opening.
Every bit you can tell, the difference between the two is hugely in favor of the unpasteurized one.
Of course,the suggested storage fourth dimension depends on the make. Ofttimes, brands recommend going with the best-by engagement printed on the label or maybe adding a couple of actress months past it, no thing when you open up the container.
That'due south because the fermentation process is ongoing, and while the cabbage volition stay safe for quite some time, it volition retain top flavour for but and so long. Similar kimchi or unpasteurized pickles (practise pickles go bad?), its taste will deepen over time, and at some point, information technology might get too sour for your taste.
As for pasteurized sauerkraut, it keeps for months past its date, every bit long as information technology's unopened. But in one case you open the container, yous only get a week and change to become the best results.
As I mentioned, pasteurized sauerkraut usually includes vinegar in brine. The vinegar helps the fermented cabbage concluding more than the usual 4 to 5 days of opening for canned foods, but the storage time is still quite limited.
Tip
Read the label. If your sauerkraut is pasteurized and the label says you can safely store it for longer than the mentioned period, follow that recommendation. Same thing if it says you should utilise it or discard information technology within 4 to 5 days.
At present that yous know how long it's good for afterwards opening, it'due south time to talk most how to shop sauerkraut.
Does Sauerkraut Need to Be Refrigerated?
Unpasteurized (raw) sauerkraut requires refrigeration at all times, while its pasteurized cousin only afterward opening the container or jar. Of class, keeping unopened pasteurized sauerkraut in the refrigerator is also an pick.
As I already mentioned, raw (unpasteurized) sauerkraut is still fermenting, and to slow downwardly that process, yous need to refrigerate it.
If you leave it on the counter, the process will speed up. And while it will non necessarily brand the cabbage go bad, its taste volition become much sharper in a matter of days.
(Which essentially makes the fermented cabbage useless or bad.)
Pasteurized sauerkraut isn't fermenting, so there's no need for refrigeration. Instead, you can care for it the aforementioned way yous treat all other canned vegetables. That means you transfer information technology to the refrigerator only subsequently you open the jar or tin can.
Having that out of the way, let's talk about a crucial storage exercise – keeping the cabbage nether the alkali.
Proceed Cabbage Submerged in Brine
Once you open up your sauerkraut, make sure everything is squeamish and submerged in brine before y'all return the leftovers to the fridge. And each fourth dimension y'all scoop some, retrieve to push downward the rest of the cabbage so that it stays covered.
Otherwise, the cabbage that's in the air will start to dry out, and inside a couple of days, there will be white specs (and eventually white film) or mold on the surface. I already talked about it in the section on spoilage.
Now, what if there's too footling brine in the container to nicely cover all the cabbage?
Fortunately, in that location's an easy solution to that issue – yous tin can make extra brine. Hither's how.
Making Extra Brine
Making your own alkali is easy. All you demand is water and salt.
We're going to make a two% (approximately) brine, which is pretty standard for making sauerkraut. If you similar yours on the saltier side, you can add more than common salt.
To make the brine, dissolve 1 teaspoon of table salt in 1 cup of h2o. If you demand more brine, double or triple the ingredients.
Once you have the solution ready, pour into the sauerkraut container as much every bit y'all need to encompass the cabbage. That's information technology.
Here's how that looks like:
In one case your cabbage is nice and covered, you tin can return it to the fridge where it stays prophylactic for months.
