DON'T BE DECEIVED ~ COMPETITORS' PRETTY PICTURES SHOW FULL JARS OF FOOD, but warn you in their instructions not to fill the jar! THE PATENT PENDING QRP OCCUPARE VITA FERMENTATION FOOD RETAINER CUP situates on the mouth of a Mason jar where it stays in place and holds the EXPANDING, fermenting food SUBMERGED underneath the brine (juices) to ferment. The CUP also keeps the juices and food from overflowing! Costly glass or ceramic weights are known to burst during the fermentation process for no apparent reason causing waste of the entire batch. Weights also tend to shift during fermentation making them ineffective. Experienced fermenters know that AIRLOCKS are needed to observe the release of oxygen bubbles, which reveals and confirms active fermentation. The Airlock releases and prevents re-entry of oxygen which causes mold in the fermentation. QRP 3-Piece Water Airlocks are easy to un-assemble and rinse, UNLIKE lids not requiring airlocks where food particles get trapped underneath difficult to remove and replace seals and date markers. The QRP lid reserves space for a date label. QRP Mason Jar Silicone Seals fit snug into Mason jar plastic lids and provide a perfect airtight, anaerobic enclosure while fermenting Pickles, Kimchi (vegetables) or Kombucha (tea) and are EASY TO REMOVE for cleaning. Metal lids or rings SHOULDN'T be used for fermentation, nor for storage of fermented foods due to eventual corrosion. QRP products were developed to help our director overcome prostate cancer.
