Our verdict

The five sets here differ mostly in pack count and published weight. The Youeon nine pack is the largest at 4.1 lb and each weight is published as about 7 oz. The JILLMO two pack is 2.0 lb with each weight published as about 11 to 13 oz. The Country Trading Co. four pack is 1.54 lb. The SOLIGT four pack is the smallest at 0.97 lb. Elementi publishes no weight for its two pack, so that figure is not available.

“Pack count and published weight decide the choice.”

Lush Editorial Team

What separates these five

Pack count Youeon supplies nine weights, JILLMO and Elementi supply two, and Country Trading Co. and SOLIGT supply four.
Published weight Youeon is 4.1 lb, JILLMO is 2.0 lb, Country Trading Co. is 1.54 lb, and SOLIGT is 0.97 lb. Elementi publishes no weight.
Individual weight JILLMO publishes about 11 to 13 oz per weight and Youeon publishes about 7 oz. The other three do not publish a per weight figure.
Stated jar fit JILLMO is stated for 1 gallon wide mouth jars. Youeon, Country Trading Co., SOLIGT and Elementi are stated for wide mouth Mason jars.
Glass type Elementi names soda lime glass. The other four state food safe, lead free or non-porous glass without naming the type.

How we chose

Priorities, not a computed score. The inputs are published specifications, so we rank by what matters most and say how much.

  1. 30% Published weightWeight is the figure that decides whether a glass disc holds vegetables under brine, and it is the figure most makers publish.
  2. 25% Pack countA nine pack and a two pack suit different batch sizes, so the count changes who the set is for.
  3. 20% Stated jar fitA weight that does not fit the jar mouth cannot be used, so the maker's stated fit carries real weight.
  4. 15% Handle designA raised or bar handle changes how the weight is placed and lifted out of a wet jar.
  5. 10% Glass compositionFood safe, lead free and non-porous claims matter for glass that touches fermenting food.

How the Five Compare on the Numbers

Published weight separates these five sets more than any other figure. Youeon states 4.1 lb for its nine pack, JILLMO states 2.0 lb for two weights, Country Trading Co. states 1.54 lb for four, and SOLIGT states 0.97 lb for four. Elementi publishes no weight at all, so it sits outside that ordering. Pack count runs the other way in places: the set with the largest published total also has the most weights, while the smallest published total comes from a four pack.

Individual weight is published by only two makers. JILLMO states about 11 to 13 oz per weight and notes the range comes from handmade production. Youeon states about 7 oz per weight. Country Trading Co., SOLIGT and Elementi publish no per weight figure, so a reader comparing single weights across all five sets cannot do it from the listings alone. Stated jar fit is broader: JILLMO names 1 gallon wide mouth jars, and the other four name wide mouth Mason jars.

The table does not tell you how any of these weights behaves in a jar. No maker publishes a holding force, a fit tolerance, or a tested brine depth. It also cannot tell you whether a weight will clear the shoulder of your particular jar, since only JILLMO addresses that with its note about gallon jars tapering inward. Treat the numbers as a starting point for fit, not a promise about the ferment.

Pack Count and Batch Size

Sets for one or two jars

JILLMO and Elementi both supply two weights. JILLMO publishes 2.0 lb for its pair, with each weight stated as about 11 to 13 oz, and states a fit for 1 gallon wide mouth jars. Elementi publishes a 2.7 inch diameter for each weight and states a fit for all wide mouth mason jars, including Ball jars, but publishes no weight for the set or for each piece.

Two weights suit a household that keeps one or two jars going at a time. The JILLMO pair is the one with a published weight, so a reader who wants to know what they are placing in the jar has a figure to work from. The Elementi pair is the one with a published diameter, which matters if the jar mouth is the constraint rather than the mass.

Sets for several jars

Youeon supplies nine weights and publishes 4.1 lb for the set, with each weight stated as about 7 oz. Country Trading Co. supplies four weights and publishes 1.54 lb for the set. SOLIGT supplies four weights and publishes 0.97 lb for the set, the smallest published total among the five.

If you run several jars at once, the nine pack covers more of them from one purchase. If you run two to four jars, the four packs sit in the middle. The published totals differ by a wide margin: Youeon states more than four times the weight of SOLIGT, spread across more than twice as many weights, so the per weight difference is smaller than the set totals suggest.

Fit, Handles and Glass

What the makers state about fit

JILLMO is the only maker that names gallon jars, and it also notes that some gallon jars taper inward below the mouth, which may prevent the weight from fitting. That note is worth reading before buying for a gallon jar. Youeon, Country Trading Co., SOLIGT and Elementi all name wide mouth Mason jars instead.

Elementi and Youeon are the only two that publish a diameter, at 2.7 inches and 2.75 inches respectively. Those two figures are close, and both are stated for wide mouth jars. For the other three sets, the maker publishes no diameter, so a reader cannot check the fit against a jar mouth from the listing alone.

Handles and glass claims

Every set here has a handle of some kind. JILLMO states a raised handle, Country Trading Co. states wide handles, SOLIGT and Youeon state a bulge handle, and Elementi states an easy grip bar handle. The purpose is the same in each listing: to lift the weight out of a jar without fishing for it with your fingers.

On glass, Elementi names soda lime glass and states it is non-porous and lead free. The other four state food safe, lead free or non-porous glass without naming the type. Youeon and Elementi state that the weights are dishwasher safe. The other three do not state a dishwasher claim, though all five describe the glass as easy to clean.

Which One Fits Your Kitchen

Large batch fermenter. Youeon supplies nine weights and publishes 4.1 lb for the set, the largest published total here. If you keep many jars going at once, this is the set that covers them from one purchase.

Gallon jar user. JILLMO is the only set stated for 1 gallon wide mouth jars, and it publishes 2.0 lb for two weights. Read the maker’s note about jars that taper inward before you buy.

Gift giver. Country Trading Co. ships four weights in a gift box and publishes 1.54 lb for the set. The presentation is the difference here, not the weight.

Small batch fermenter. SOLIGT supplies four weights and publishes 0.97 lb for the set, the smallest published total among the five. It suits a few small jars rather than a full shelf.

Diameter conscious buyer. Elementi publishes a 2.7 inch diameter for each weight and states a fit for all wide mouth mason jars, including Ball jars. It publishes no weight, so buy it for the fit.

What We Could Not Verify

Several figures a reader would want are absent from the listings, and I did not fill them in.

  • Elementi publishes no weight for its two pack or for each individual weight.
  • Country Trading Co. publishes no per weight figure, only the 1.54 lb set total.
  • SOLIGT publishes no per weight figure, only the 0.97 lb set total.
  • No maker publishes width, depth or height for the set as a whole.
  • No maker publishes a tested brine depth or a holding force for its weights.
  • Only JILLMO addresses jar shoulder clearance, and only for gallon jars.

Frequently asked questions

What is the heaviest set here?+

Youeon publishes 4.1 lb for its nine pack, the largest published total among the five. JILLMO publishes 2.0 lb for two weights, Country Trading Co. publishes 1.54 lb for four, and SOLIGT publishes 0.97 lb for four. Elementi does not publish a weight, so it cannot be placed on that scale.

Which set has the most weights?+

Youeon supplies nine weights in one set. Country Trading Co. and SOLIGT each supply four, and JILLMO and Elementi each supply two. If you ferment several jars at once, the nine pack covers more jars from a single purchase, while the two packs suit one or two jars.

Do any of these fit gallon jars?+

JILLMO states that its large glass weights fit 1 gallon wide mouth jars. The maker also notes that some gallon jars taper inward below the mouth, which may prevent the weight from fitting. The other four sets are stated for wide mouth Mason jars rather than gallon jars specifically.

Which set states an individual weight?+

JILLMO publishes about 11 to 13 oz per weight, and notes the figure varies because the weights are handmade. Youeon publishes about 7 oz per weight. Country Trading Co., SOLIGT and Elementi do not publish a per weight figure, so only two of the five sets can be compared that way.

Which set states a diameter?+

Elementi publishes a 2.7 inch diameter for each weight and states a fit for all wide mouth mason jars, including Ball jars. Youeon publishes each weight as 2.75 inches across and 1.4 inches tall. The other three makers do not publish a diameter for their weights.

Does any maker name the glass type?+

Elementi names soda lime glass. The other four state food safe, lead free or non-porous glass without naming the type. All five makers state that the glass does not absorb food odors, flavors or colors, which is the property that matters for repeated fermenting batches.
