During the fermentation process, the food expands and rises. QRP'S PATENTED OCCUPARE VITA FERMENTATION FOOD RETAINER CUP situates on the mouth of a Mason jar where it stays in place, KEEPS ALL FOOD SUBMERGED in the brine (juices), and PREVENTS MESSY OVERFLOW. Costly glass or ceramic weights can chip or burst during the fermentation process for no apparent reason causing waste of the entire batch. Experienced fermenters know that AIRLOCKS are dependable in observing the release of oxygen bubbles, which reveals and confirms active fermentation. The 3-Piece Airlock allows the system to exhale oxygen and prevents re-entry. QRP 3-Piece Water Airlocks are easy to un-assemble and rinse, unlike lids without 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. The QRP Fermentation Kits include Silicone Seals which fit snug into the 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.
