4-Pack of Fermentation Glass Weights with Easy Grip Handle for Wide Mouth Mason Jars

Nice and heavy. If you have big hands, the grip on top may be hard to pick up. Worked great.

I bought these as they seemed like a good value, which they are. However as nobody else has mentioned it, these weights are not flat on the lower surface, they are concave. So there is potential for gas trapping under them, although the theory is that the concave surface produces a suction effect that keep the weight in place.They are well packed, and seem like good quality glass.I like the handle, tried it in a bowl of water and they are easy to grip and lift. I am going to get a set of the more expensive flat bottomed ones and compare them, and update the review after that.-- update --After comparing flat to concave weights i can say they both work as intended and stay put with no gas underneath.I am happy with these, they work well and keep both finely chopped and coarsely chopped items under the brine. I have tried them from finely chopped sauerkraut to do chua (daikon and carrots), the weights work well and are easy to grab and remove, except of course when the jar is nearly empty, but by then no weight is usually required as there is a lot of brine left.I saw a reviewer mention they do not work well in 1/2 gallon mason jars, as the jars a wider. So i tried it. I found even sauerkraut submerged well in a 1/2 gallon jar. Yes there are a couple of small pieces that escape, but they do not seem to actually reach the surface, the suction effect of the weight seems to keep everything down anyway.I even tried the weight on a jar of Trader Joe's sauerkraut (with the cucumber in it), that jar is much wider than the weight, and square. It even worked perfectly in that, the weight kept all the contents down below the brine, no problems at all.I have upgraded my rating to 5 stars. Even when covered in brine i have no problems grabbing the weight and removing it.

These Fermentation Glass Weights are exactly what I needed for my fermenting projects. They fit snugly inside my fermentation jars, keeping vegetables submerged under the brine effortlessly. The quality of the glass is excellent—durable and easy to clean. They have significantly improved the success of my fermentations by ensuring an anaerobic environment. If you're into fermenting foods at home, these weights are a must-have. Highly recommend!

I subtracted a star in rating these weights because it can be difficult to lift when the handle is wet. It would be better if the handle were textured with horizontal grooves.HISTORYWhen I first started making sauerkraut, my biggest challenge was massaging enough juice out of the cabbage for the brine to cover the ferment. I have since learned to look for cabbage that 1) looks fresh (higher moisture content) and 2) is harvested in the winter (higher sugar content favored by Lactobacillus). Because these two are not always possible, I have adapted my recipe to include English cucumber and carrots (the fresh ones with greens attached, which I then remove) to add fluid and flavor. The common fix for insufficient brine is to add water; however, I found that the resulting kraut had noticeably less flavor. My next kraut challenge was to find smaller fermentation vessels so that I wouldn't have to keep transferring from my three-gallon crock to a jar with enough capacity for a week's worth of eating. I saw that folks were using mason jars, and then that discovery led to SOLIGT (so legit?) lids. On my first use, after filling the jars with ferment and sufficient brine, I put the lids on tightly and sucked out the air. After a week, I went to my garage to find brine puddled around the outside of the jars.WHEN TWO IS NOT BETTER THAN ONESometime after my first use of the lids, I discovered these SOLIGT glass weights. When fermentation is in high gear, Lactobacillus produce gas that can loosen the ferment and carry it to the surface as the bubbles travel upward. I use a dinner plate to keep the ferment submerged in my three-gallon crock. Thinking that using lids and weights would be ideal, I proceeded (Day 0). As I pumped air from the jar, I saw the brine level rise above the glass weight (Day 1). Recalling basic science, I realized that the space formerly occupied by the air was now being filled by the expanding brine. It was then that I realized why the first attempt had resulted in a briny mess: The Lactobacillus gases created pressure inside the jar with a result similar to, but not as dramatic as, opening the lid of a shaken carbonated drink. From Day 1, therefore, I replaced the SOLIGT lids with standard canning lids placed loosely. Day 3 on the kitchen countertop was the peak of fermentation, with the gas having pushed the brine to nearly overflowing. By Day 7, the brine level had receded with the end of fart production and I knew that it was time to remove the scum and enjoy some kraut! After tasting the kraut, I put one jar in the fridge and the other in the garage for those in my family who prefer a more tart kraut. The way I see it, SOLIGT weights are appropriate for ferment with sufficient brine, while SOLIGT lids are appropriate for ferment with insufficient brine. Either tool insures that fermentation takes place without contamination from non-beneficial, oxygen-breathing microbes. You could use the combination of weights and lids in either scenario, but it's redundant, at best.I have since repurposed the SOLIGT lids for storage of bulk matcha. I replenish the vacuum every three weeks. That's excellent, based on my experience with various vacuum stoppers.

These glass weights are perfect for keeping food weighted down when fermenting. They are heavy enough, perfect size, and easy to grab onto and place into the jar and retrieve when needed.

Works perfectly.

These are great for fermenting and I love the knob to hold onto on the top. It makes it so much easier to get them out of the jars.

I inquired about one fermentation weight that defective and couldn't be picked up as the picture shows. The stem was too short to be picked up. I suggested a replacement for that one piece. I did not get a replacement but they refunded me the full amount. I wasn't expecting it. I am here to say the company was very quick and extremely polite and resolved the issue to my full satisfaction. I would buy from them again.
