Introducing The reCAP® Fermenter: the EASIEST waterless airlock set that ferments and stores culinary creations that are delicious and good for your health. For both regular mouth and wide mouth Mason jars. This tried and tested solution is simple to use, with less pieces and steps, and better results than traditional methods and current Mason jar fermenting tools that we’ve tested.
reCAP® Fermentation is different. We wanted a low-profile, waterless airlock that had an authentic one-way valve to let gases escape and absolutely not let air in. Something that eliminated the need to monitor the jars every day, but made it easy to peek in and taste when desired. We wanted something that could easily convert to plain storage to put in the refrigerator when complete. The reCAP Fermenter makes fermentation AND storage easier and more fun. From sauerkraut to kimchi, kefir to kombucha, we encourage you to Make It Yours and we think you’ll love it!
What is Fermentation and How Does it Work?
Lacto-fermentation is a method of preserving food, but in addition creates a super-food because it encourages the growth of beneficial bacteria known as probiotics. It is how yogurt, giardiniera, sauerkraut and kimchi are made.
The process is anaerobic (ie, absence of oxygen). Vegetables exposed to oxygen encourages the growth of mold and can lead to nutrient-poor, soggy food. Once proper fermentation begins, the sugars convert to lactic acids and it creates carbon dioxide (the bubbles!). So it's important to allow gases to escape but keep the oxygen from entering.
The reCAP® Solution
Mason jars are considered the perfect vessel for fermentation. reCAP Mason Jars converts the already popular POUR cap into a fermenting tool with our reCAP Fermenter. It is a simple waterless airlock that fits into a stopper. Once the ferment is complete simply remove the stopper, press down the POUR lid and it's ready for storage! The reCAP Fermenter can then be used in another batch. No need to scramble for lids and rings.
EASY - Low profile, Waterless Airlock (no maintenance) & interchangeable between regular and wide mouth Mason jars. Quick Clean Up & Dishwasher safe.
SAFE - Rust-free, BPA-free, Food Safe Plastic. True One-way Valve (allow gases to escape and will not let air in)
DURABLE - An Economical, Multipurpose Solution that will last for many years.
NO maintenance or monitoring required.
How Does reCAP® Fermentation Work?
The reCAP Fermenter uses a legit one-way valve system. Just as it sounds, a one-way valve allows the flow of a gas or liquid in only one direction. This is the purpose of an airlock: to allow carbon dioxide gas to flow out of the jar, and prevent oxygen (or anything else) from flowing into the jar.
Utilizing the original reCAP POUR, the Fermenter creates an air-tight seal with the one-way valve and stopper. No screw bands needed! During the ferment, the carbon dioxide releases through the valve as pressure builds up within the jar.
When done, simply remove the Fermenter and the reCAP POUR turns into a storage cap. It is the most multi-functional fermenter available!
Wei-Shin: "The food was so yummy! So much better than other fermented foods I've had previously."
Steve C: "We do the usual canning from the garden, but for me, reCAP is definitely about the fermenting. Jalapeños, sauerkraut, okra, onions and more. When I started making sauerkraut a few years ago, I didn't have the right tools at hand for keeping the ferment environment on track. I knew it was an anaerobic process, but getting a good seal around the top of an old German crock (that we didn't have the original lid for) was problematic. At that time, I made sauerkraut slightly more than 50% of the time; the rest were compost-ready disappointments. Soon thereafter I found reCAP. I haven't lost a single ferment since."
Mary: "I'm using these for beverage fermentations. I'm currently conducting a short mead & cider yeast trial - each half gallon mason jar is topped with a wide-mouth reCAP, a #5.5 stopper & an air lock. I capped 14 different mason jars full of honey/water mixture or apple juice & shook to combine with yeast nutrient - not a single one leaked. They are bubbling away currently. I'm elated with these for use in fermenting beverages and look forward to using them for pickles & other veggies in the future!"

Risks and challenges
This is our fourth Kickstarter project! We have learned a lot in that time and our project timeline is very sound. We built and identified sources for everything we need and are now working on the final acquisition, assembly, packaging and printing. We will be ready to fulfill orders once we have successfully funded the project.Learn about accountability on Kickstarter
