Fermentation Questions

What material is used to make the waterless airlock?  Silicone
How does the waterless airlock work & how do you clean it? The waterless airlock is a one-way valve. It allows gases or liquids to flow in only one direction. The purpose of the airlock is to allow carbon dioxide gas to flow out of the jar and prevent oxygen (or anything else) from flowing into the jar.

We recommend cleaning the airlock by hand with mild soap. Since it’s a one-way valve, water will only flow in the direction of the arrow on the airlock. Make sure to run water through the airlock to get all the soap out.
How is the reCAP fermenter different from other fermenters? What else can I use this kit for? Unlike most other fermentation products, reCAP includes a low-profile, waterless airlock. Some of the benefits are:

1. No need to monitor the water level.
2. The 3-piece airlock is made from a brittle plastic that can easily break. The reCAP fermenter is almost indestructible.
3. The reCAP fermenter is much easier to clean.
4. The reCAP fermenter is a much lower profile, therefore it better fits on shelves.

In addition, there are many uses for a waterless airlock! It can be used to store your coffee to keep fresh, brew small batches of beer, and more.
Product Care
My Mason jar lid leaks, what is the problem?  First make sure that there is a gasket inside and it is lying flat. Then make sure the lid is threaded straight on the jar (not askew) and tighten. Double check the fit is tight! Some Mason jars may not successfully seal due to severe variations. Older Mason jars especially may have been altered or are non-standard. Since these will not be 100% leak-proof on every jar variation, keep in mind that they are also great for dried goods and pantry items as well! 
Can I use my Mason jar lid for canning or in the microwave? No, reCAP® Mason jar lids and most plastic are not to be used in canning or microwaving.
Can I put my Mason jar lid in the dishwasher? Yes. While it is not recommended to heat plastic, reCAP® POUR Mason jar lids can be washed on the top rack dishwashers. Hand-washing with a mild soap is preferred and recommended to extend the lid’s life.
Will the reCAP Mason jar lid stain? Independent Lab testing show that the lids are stain resistant.
Can I remove the gasket for cleaning? Yes, gaskets are easy to clean by hand or in the top rack of a dishwasher. We also sell replacement gaskets if needed.
My Mason jar lid is stuck on my jar, how can I get it off? Sometimes lids can be a little stubborn, try using the pour spout as leverage with your thumb and opening the flip lid to reduce potential vacuum pressure. If it's still a little tricky, fill the jar with hot water and let it sit upside down for a minute before trying to remove the lid. New gaskets can also be purchased if the gaskets are worn.
I’m having a difficult time opening the ‘flipper’ on my reCAP POUR Mason jar lid, how can I open it easier? If the flipper lid is difficult to close or open, try adding a drop of cooking oil on your finger-tip and lubricating around the edge/sides of the closure. You should only have to do this one time, and the problem will be resolved, even after washing the cap.
What are the maximum working temperatures for the POUR Cap? In a lab test it was determined that our caps are dishwasher safe and can withstand effects of extreme temperature change of 0°F and 120°F.



If the Mason jar lids are made of plastic, then how can they be eco-friendly?  reCAP® Mason jar lids are considered “smart” plastic. They are not disposable and reCAP is guaranteed to be long lasting. The lids allow you to reuse glass Mason jars in unique and sustainable ways that eliminate the need for plastic bottles or containers.
How can I recycle the Mason jar lid once I am done with it? Most local recycle agencies now take #5 Polypropylene. If not, contact your local agency for information on recycling.
Is the packaging recyclable? Yes, the packaging is recyclable, reusable and all the kraft packaging is compostable.
