Fermentation is practiced at home for many reasons including preservation, flavor enhancement, tradition and suggested health benefits. Common fermented foods are sauerkraut, kimchi, pickles, yogurt and kombucha. Foods are preserved by adding bacteria that converts sugars into acids. The higher acidity of these foods preserves them by preventing the growth of harmful bacteria. On this page you will find resources for safely fermenting foods at home.

Fermentation is the process of using bacteria and/or yeast to convert the foods’ carbohydrates into acid, carbon dioxide and/or alcohol which then work to preserve the food from spoilage. Vegetable fermentation rely on Lactic Acid Bacteria or LAB to help with this preservation. It is the primary bacteria in Sauerkraut, Kimchi and fermented pickles. For more of the health benefit, refrigerate these fermented foods which allows for the beneficial bacteria to provide some of their protective support to our immune system.

Here are some of the most common fermented vegetables you can make at home.

Kimchi

  • Naturally fermented vegetables usually Napa cabbage or radishes but other vegetables are possible to use.
  • Taste regularly until it reaches the desirable flavor.
  • Store in the refrigerator or can be frozen for longer storage.

Sauerkraut

  • Naturally fermented product using cabbage and canning salt.
  • Sour taste created when LAB coverts cabbage’s carbohydrates to lactic acid
  • Store by refrigerating, canning (but may lose probiotic benefits) or freezing
  • Sauerkraut Recipe

Fermented Pickles

  • Naturally fermented cucumbers
  • Ferments in a brine prepared from canning salts, vinegar and water
  • Store in refrigerator or by canning.
  • Fermented Pickles Recipe

It is important when fermenting to be at the correct temperature. Below 60ºF and foods may not ferment and temperatures above 75ºF may result in fermented foods being too soft or spoiling before they ferment.

You also want to make sure you use the proper containers when fermenting. You do not want to use aluminum, copper, brass, galvanized or iron containters since they can react with the acid. It is best to use large stoneware crocks, large glass jars or other food grade containers.

Fermented foods can be stored in the refrigerator at 41ºF or below for up to 3 months. Sauerkraut and fermented cucumber pickles can be canned in a boiling water bath for longer storage. Kimchi and Sauerkraut can also be frozen.
