STARTER KIT 6 Mason Jar Fermentation Lids with Food Grade Grommets, Airtight Seals, and Stoppers AND 2 3-Piece Airlocks (WIDE MOUTH)
The STARTER KIT is offered to those who wish to ferment 2 jars while storing 4 jars of fermented food or beverage.Without some form of gasket, the mason jar white plastic lids are not airtight. Quality Reliable Products Mason Jar Silicone Rubber Seals fit snug into mason jar white plastic lids.  We tried the narrower red seals with the smaller outer diameter.  They tend to become displaced while tightening the lid, and unfortunately, they did not keep our fermentation jars airtight - see photo.  Our reliable seals provide a perfect airtight, anaerobic enclosure while fermenting Kimchi (vegetables) or Kombucha (tea).Metal vs. Plastic Lids use for fermentation and storage of fermented foods?  We find that whatever we are fermenting does not normally come in contact with the lid during fermentation, but however, may briefly come in contact with the lid during storage.  We've done the research, which reveals that metal shouldn't be used during fermentation, nor for storage of fermented foods.3-piece Airlocks supersede the S-Curve Bubble Style Airlock because they are more sturdy and easier to keep clean.THANKS FOR SUPPORTING  SHINE IN THE DARK COMMISSION, A MEMPHIS INNER-CITY MINISTRY!
