Ball14400108204 Fermentation Kit, 32 Oz, Clear, 4-Piece Set

Works well.

I use these after my ferments are complete (and have been moved into the fridge for consumption.) They are great and keep my ferments fresh by keeping the compacted veggies under the brine.My routine is to ferment for 3-4 weeks (mostly cabbage) with glass weights in (1-quart, wide mouth) mason jars following the measurements and recipes in the book, “Fermentation Made Easy!” by Holly Howe. Ms. Howe recommends saving a cabbage leaf to create a barrier between the veggies and the weight, to keep floaters from rising to the top of the jar, (where they can be exposed to oxygen and thus mold or rot.). That barrier is especially important for shredded produce.While I prefer to make the ferments with glass weights, I don’t feel that they keep the completed product submerged once I start eating it. That’s where this product shines.The spring, (WITH that intact cabbage leaf), compresses the sauerkraut and keeps it well below the brine line, ensuring that, when I’m ready to eat out of that jar, that it’s crunchy, fresh and perfectly preserved. Usually I scoop a weeks worth into smaller jars and stick the glass weights in those, so I’m not messing with the “master” jars on a daily basis.The pic illustrates the different levels of compression between the glass weights (small jars on top) and this Ball lid/spring product, (larger jars on bottom). I can see how pickle spears or other whole ferments might not be suited for this item, but for shredded produce, it works great and perfectly suits my needs.

These lids are amazing for burping the fermenting product. Easy to switch lids once the product is fermented. This product is excellent. I did have to get smart to keep my fermented vegetables down below the water level… The spring helps but I needed for example a circular shape of large cabbage to keep all the tiny cabbage bits down. Works amazing though.

Worth every single penny. It is a bit expensive but u save a lit of money in the long run by making your own sauerkraut or other fermented vegetables. Easy and hassle free procedure. No need to open tge bottle in-between to let the gas out. It does exactly what it is described. Very impressed. Thank you

The product is great. However, the listing specifies it includes 4 kits but I've only received one.
