Fermenting is a science, and a bit of an art. It requires care in a few specific things, but doing it right is not particularly complicated. We provide instructions that are accurate to the best of our knowledge, and which are based on the methods we successfully practice ourselves. There are no guarantees of success or safety with fermented foods. While properly fermented foods are not only safe, but healthy to eat, it is up to you to follow instructions to ensure safety, and to trust your eyes and nose, and don't eat things that do not look or smell like food. We offer no guarantees of success with our product. We do warrant that it is as described, and will do what we say it will, but how you use it is your choice.

Periodically some new study will come out telling you how you are eating your foods all wrong, and how mankind has been duped for the entire history of the world into eating things that are harming them, and that this or that process is necessary in order to avoid the pitfall that the study somehow proves is unavoidable otherwise.

Hence we have groups of people dedicated to one extreme or another of eating, in complete disregard to the fact that historical patterns from society to society are a pretty accurate predictor of what is and is not sustainable.

Some of natures rules that we tend to forget:

  • There is no society in the world at any time in history that espoused a vegetarian or vegan diet without the addition of meat, fish or insect protein, usually two or more of those. No society has thrived under a meatless diet.
  • Sprouting and fermenting of foods was done as a supplement to seasonal eating, as a way of extending fresh food seasons, in all historic societies that practiced these preparation methods.
  • “Miracle foods” do not exist. Food, in and of itself, is a miracle, when it is fresh, not contaminated with things that the body should not be assaulted by, and when it is consumed in variety.
  • The best “medicinal supplements” are those that have a long history of being used in significant amounts in a thriving society somewhere in the world. Examples: Cinnamon, cocoa, coconut oil, oily fish (NOT extracted oils), whole wheat, dill, etc.
  • “Antioxidants” can be found in ANY fresh fruit or vegetable. They are not miraculous. They are elements in fresh foods, and ALL wholesome fresh foods aid in slowing cellular damage in the body.
  • Alcohol is consumed in every society in the world. But it is also KNOWN in every society in the world to be harmful to one extent to another, and is always the subject of some controversy due to negative health effects. This is true of many things, where an item may be accepted in a culture, but is also controversial in that culture.
  • More harm is done by trying to disinfect food than is done by the microbes that are considered harmful. Bacteria, molds, yeasts, and other microbes combine in variety to expose our bodies to both helpful agents that aid in the breakdown of food and low exposure to “harmful” agents that strengthen our immune system and often aid in ways we do not anticipate.
  • Nature does not rule by extremes, but by variety, and common sense.

Nature is not trying to trick us, and while science is discovering new benefits and cautions regarding food all the time, the fact is that a varied diet of fresh and whole foods is still the best way to stay healthy.

It is not as though mankind has been eating their vegetables all wrong until the last few years when a partially completed study suggested that some foods may cause a negative effect when processed in a laboratory. Not logical!

Food problems are NOT historic. They are recent. Escalating disease rates are also NOT historic, but of RECENT development.

Hence, we may assume that it is MODERN man that has eating all wrong, not HISTORIC man. We may know more about what food does in the body, but we also have more contaminants and our food is more processed and stripped of many of the elements which we need for optimal health.

  • There is NO society that fermented foods exclusively in a closed containment. They were fermented in MANY ways, in all societies, as a means of preservation.
  • There is NO society that consumed exclusively sprouted grains. Most grains were consumed after being cooked, or ground and baked.
  • There is NO society that ate exclusively COOKED vegetables, or exclusively RAW vegetables. ALL successful societies, even nomadic, consumed a combination of raw and cooked foods, depending upon the food.

Eating well is a fairly simple prospect, once we know that we only need a good variety of healthy foods, that have been affected by chemical contaminants as little as possible, and which have not been “refined” in a way that strips them of nutrients. The more natural microbes they happen to contain, the better.


The ORIGINAL one-way valve fermenting airlock! Imitation IS the sincerest form of flattery, and we have noticed that our product has been copied by other sellers of fermenting products. Remember, if you see someone else selling a one-way valve airlock for fermenting, THEY copied US, not the other way around! Fermenta Lock is still the only original invention, handmade in the US. If it isn't orange, it isn't the original!

We invented Fermenta Lock, Fermenta Free, and the valve used for Fermenta Fido and other Fermenta Airlock products. We invented Fermenta Dunk Extender. Patents are prohibitively expensive, and designed by the government not to protect the rights of individuals, but to provide another source of revenue and control for the government and lawyers. We are good at what we do. We have endless ideas and endless creativity, and competition does not scare us. Impatient thieves do not scare us - they are too busy taking shortcuts to make a success of it anyway, and they won't want to take the effort to actually MAKE a product and fill orders.

So if you want to copy our idea, go right ahead. If you want to market and sell a competing product, you are welcome to do so, as long as you do not patent our idea - we had it first, and our posts on FaceBook announcing the invention and launch of it will prove that. This idea is officially in the public domain, placed there by us. We will NOT release supply sources, or part names unless you want to buy them - we'll be happy to sell you an instruction kit. If you buy our product, or look at the images and figure it out for yourself, good on you. Compete with us if you like, just don't screw us, and we'll get along just fine. Big companies who might want to screw us may have more money, and more lawyers than we do, but we have more to gain by suing the pants off a big company, and believe me, we will be well motivated to do so if anyone patents our idea and claims it as their own - this is a free idea. Everybody now owns it.

Customer Comments

“Living down in Guatemala, we have quite a lot of dampness in our houses and mold is an ongoing battle. After a long dose of antibiotics due to a parasite, I absolutely required probiotics to get my gut back in order and I know homemade sauerkraut has more probiotic content than anything else I could find here. I wasn’t able to make my beloved sauerkraut or even Kombucha in my kitchen because mold would start growing immediately on the top. Your Fermenta Locks have literally been a lifesaver for me! No more mold, and PERFECT Kraut EVERY time!!! Thank you for creating such a wonderful product!!!”

“Oh how I wish I had found you first!! Too many experts and too many bucks later I discovered your “Lock” and the sheer elegance and simplicity of your system.Thank you for your help and affordability, it makes healthy food attainable.”


“I came back to order more FermentaCaps. A wonderful innovation. I have not lost a single batch of sauerkraut since I started using the original Fermenta Locks.”


“Please continue your good work on producing such a great product. I’ve tried lots of other kinds of airlocks- the 3 piece water lock, pickle pipes, fermilid, boss pickler, and I think yours is the best design and quality. I’d like to order another 100 of them right now, but I’ll have to wait a bit. I’ve had lifelong health challenges. I’m 38 and about 20 years ago my health was so bad I didn’t feel like living most of the time. Now my health is the best it’s ever been and it wouldn’t be possible without fermented vegetables, they have made a huge improvement in my health.”
