  • Equipment for Fermenting Vegetables

    My first attempts at fermenting foods were disastrous. Many times, I ended up with slimy, moldy cabbage that was not only un-appetizing, but unsafe to eat. What was I doing wrong?

    Equipment for Fermenting Foods

    Having the proper equipment for fermenting vegetables is critical to success. Why? Because you need to keep you food submerged below the level of liquid.

    The first time I tried to make sauerkraut, I didn’t know that. Fail.

    After I learned this truth, I tried to make fermented pickles. Keeping the cucumbers under the brine with a plate was real tricky. I ended up with some moldy ends. Gross.

    Fermenting Crocks

    Then, I thought about getting a fermenting crock. My husband had picked a couple up from an auction and I used one to store kitchen utensils. I had a few more in the attic. But with those, I still had to weight down the food with a plate on top.

    You can buy new fermenting crocks that come with weights. That sounded like a good idea. But they cost a lot of money. The cheapest I could find was $70. They are also heavy. And I am not a very strong person. I also have a tile floor and everything that hits it breaks into a million pieces. I would be heart-broken to drop a $70 crock on the floor and have it break.

    Then I found Fermentools.

    Canning Jars

    The weight we sell fits into a wide-mouthed canning jar. Canning jars are cheap and light weight. If I drop one and break it, I have 50 more just like it in the cupboard.

    Air Locks

    Another important component of fermenting foods is keeping oxygen away. Oxygen provides the environment that bacteria need to grow, and you do not want that. So we sell air locks that fit perfectly into the lid (with the help of a rubber stopper) to prevent that from happening.


    Our specially designed lid fits inside a standard, wide-mouthed canning lid ring. You don’t have to worry about your lids and jars being compatible. Also, in our kits we include rubber stoppers with holes to accommodate the air locks and rubber stoppers that are solid. Once you remove the air lock, simply replace the stopper with a solid one before putting your product in the refrigerator. Of course, if you want to immediately start another jar of fermented goodness, you can replace the fermenting lid with a standard canning lid.

    You can get a six-pack kit for about the same price as that crock I found. That kit will allow you to ferment six different recipes at the same time. With the crock, you are limited to one recipe. Me? I’ll take the variety every time.

    What do you use to ferment your foods in?

  • Lactose Intolerance and Lacto-fermentation

    Because fermented vegetables often are called "lacto-fermented," some think that people who are lactose intolerant cannot eat fermented vegetables. However, that is usually not the case. Read on for more information on this oft-confused topic.

  • 3 Amazing Health Benefits of Fermented Foods

    I love sauerkraut. I frequently crave that sour flavor and the pleasant tanginess it brings. I eat it plain, right out of the jar. I eat it on hot dogs and sausages. (Don’t tell folks I eat hot dogs, okay?) I even eat it mixed in a salad.
