The lactic acid fermentation of sauerkraut and vegetable pickles is initiated by the bacteria Leuconostoc mesenteroides. When compared to other lactic acid bacteria, it is able to handle relatively high amounts of salt and sugar. It generates CO2 and acids, which rapidly reduce the pH of the water and prevent the growth of spoilage bacteria in the water.
How long should you ferment sauerkraut for?
- The quick answer is that it will take two weeks. The long and the short of it is: it depends. Typically, sauerkraut (or any other fermented vegetable for that matter) is ready to consume in 3 to 4 days after it is first made. Sauerkraut, on the other hand, was historically fermented in crocks for up to six weeks or more, depending on the recipe.

Why does sauerkraut ferment?
The cabbage is coarsely shredded, coated with salt, and let to ferment for a few days before serving. Because these airborne bacteria cultivate on fresh cabbage leaves, where they flourish, lactobacilli are spontaneously introduced into the fermentation process. Yeasts are also present, and if the fermentation temperature is raised too high, the result might be mushy sauerkraut with a terrible flavor.
How do you stop fermentation in sauerkraut?
Because the acids have accumulated to such an amount that further development is no longer possible, fermentation comes to an end spontaneously. You should not disturb the crock until the usual fermentation process is complete if you soak the cabbage in a brine-filled bag before cooking (when bubbling ceases).
What causes most of the spoilage problems affecting sauerkraut?
Overgrowth of the lactobacillus, which can occur, for example, if the jar is stored at an excessively high temperature during fermentation, can result in the sauerkraut forming a thicker consistency than desired. Despite the fact that the completed sauerkraut is far too acidic for pathogens to survive in, fungal spores may collect on the surface and spread, resulting in the dish being spoiled.
How can you tell if homemade sauerkraut is bad?
The presence of an off-smelling scent is one of the first symptoms that the sauerkraut has gone sour. It is possible that the sauerkraut has gone bad when it emanates a strong decaying stench from the product. Examine the fermented cabbage to see whether it has developed an unusual texture or color. If there is substantial texture or discoloration, the product should be discarded.
Why is lactic acid in sauerkraut?
The term “lactic acid” is used to describe this form of fermentation, not because it contains any dairy products (it does not), but because it is caused by lactic acid bacteria (LAB), which are responsible for the fermentation process. This lactic acid imparts a sour flavor to ferments, similar to that of vinegar, and serves as a preservative for sauerkraut and other fermented vegetables.
Why did my homemade sauerkraut mold?
Because it may take some time for the bacteria to produce gases, having too much air in your jar might result in mold and yeast development in your container. The CO2 gases in the jar drive the oxygen out of the container. Increase the amount of cabbage or transfer it to a smaller jar. Fermentation takes place at colder temperatures.
Does sauerkraut need to ferment in the dark?
Darkness is beneficial to lactic acid-producing bacteria (LAB), which are the microorganisms responsible for fermentation. Light is detrimental to LAB, as it destroys them. Although ultraviolet light appears to be favorable to yeasts in the amounts that enter the jar, it should be avoided if at all possible.
How do you know when sauerkraut is fermented?
Upon reaching the 7-day mark (5-day if fermenting in a warm area; 10-day if your house is exceptionally cool), remove the tiny jar or weight and take a whiff of your sauerkraut before tasting it. Eventually, it should begin to taste sour and no longer have the taste of salted cabbage. Its colors should be fading rather than vibrant, as they would be with fresh cabbage.
How do you know when sauerkraut is done fermenting?
In around 4-6 weeks, your sauerkraut should be ready. When bubbles no longer occur in the liquid, you will be certain that the process has been completed. You will notice a difference in the flavor as time goes on. The longer you leave the cabbage to ferment, the tangier it will be.
Can you get botulism from homemade sauerkraut?
Is it possible to get botulism by eating lacto-fermented pickles or sauerkraut? No. Botulism does not thrive in fermented foods because they produce an inhospitable environment.
Why does my sauerkraut smell like alcohol?
Fermentation scents are normal. The fermentation process is complete when the ferment smells sour, suggestive of vinegar, fresh, or tangy. If Kahm yeast has taken up residence, the stench may even be yeasty, beer-like, or alcoholic in nature.
Do you put a lid on sauerkraut?
Place the jar on a shelf and allow it to ferment for a few days. I recommend that you use a plastic lid rather than a metal lid since metal lids can rust. It’s important to keep an eye on your sauerkraut during the fermentation process. If the liquid level falls below a certain point, top it off with a 2 percent solution of sodium chloride.
How long should I leave sauerkraut to ferment?
Allow for at least five days of storage in a dark area at a cool room temperature (about 18-20 degrees Celsius). You may consume it after five days, but for the best flavor, allow it to ferment for anywhere between two and six weeks before eating it (or until the bubbling subsides).
