What Is Vegetable Fermentation?
Vegetable fermentation refers to a natural microbial process called lactic acid fermentation. During this process, beneficial bacteria, primarily Lactobacillus species, consume sugars in vegetables and produce lactic acid. This acid not only gives fermented vegetables their signature tang but also acts as a natural preservative, inhibiting the growth of harmful microbes.
All you have to do is combine vegetables with the right salt amount and submerge them in their brine. The microbes do the rest. In other words, you’re not fermenting, the microbes are. Your job is to create the ideal environment for them to thrive.
Which Types of Vegetables Are Fermentable?
Most water-dense vegetables can be fermented when prepared with the right salt concentration and fermentation time. While that might sound technical, it’s simpler than you’d think and incredibly rewarding.
If you’re just getting started, cabbage-based ferments like sauerkraut are a perfect entry point.
Cabbage naturally contains the proper moisture balance and beneficial microbes, making it a reliable and forgiving vegetable to wild ferment. Below, you’ll find flavorful twists on classic kraut recipes to kick off your fermentation journey.

Other Vegetables You Can Ferment
Once you’ve gotten comfortable fermenting cabbage, you can confidently branch out to other vegetables. I always recommend starting with krauts and kimchi and then trying vegetables that are technically fruits, like cucumbers and peppers.
As you gain experience, you can begin experimenting with your own combinations and recipes. Just remember: creativity is welcome, but safety is essential. Certain vegetables require specific salt percentages and environmental conditions to ensure safe fermentation. Before you branch out too far, I recommend reviewing these two helpful guides:

Why You Should Ferment Vegetables
Fermenting vegetables isn’t just about preservation, it’s about transformation. With salt, time, and beneficial microbes, you can turn fresh produce into probiotic-rich, flavor-packed foods that support gut health and digestion.
Fermented vegetables are loaded with live cultures, prebiotic fiber, vitamins, and minerals. Regularly incorporating them into your diet can improve immune function, reduce inflammation, and improve nutrient absorption.
While fermentation dates back thousands of years, it’s no longer just a folk practice. It’s a scientifically understood, time-tested method that makes your food more nutritious, flavorful, and shelf-stable.
Things You Need to Make Fermented Vegetables:
Hello! Thank you so much for this–it is reassuring to have more information on the science behind the fermentation process, which has always made me nervous! I am running into an issue, however: when assembling the ingredients for my jar of kimchi or kraut, it’s hard for me to know exactly how much water to use. I recently mixed up a batch of salt/water brine for my vegetables by estimating how much water I’d need, but it ended up being too much for the veggies + the jar. I had to up ultimately dump some out, which changed the ratio again. I actually had to dump some more out after the vegetables fermented for a couple of days, changing the ratio yet again. Any tips on how to approach adding the salt and water to the vegetables?
