Among fermentation weights under 100, the Westmark set keeps things straightforward with four solid glass pieces sized for common fermentation projects. Each 7 cm weight includes a handle for placement and removal, and the hygienic design is intended for easy cleaning.

- Handles make placement and handling more convenient.

For fermentation weights under 100 that cover larger containers, this ceramic split-weight design measures 4.3 inches across and is intended for wide-mouth jars, fermentation crocks, and containers at least about 4.3 inches wide. Its glazed, non-porous surface is dishwasher-safe and resistant to salt water and acid.
Best For: Gallon-size and larger fermentation crocks, wide-mouth jars, and larger batches of cabbage, sauerkraut, or kimchi.
Pros:
- Large 4.3-inch diameter provides broad coverage.
- Two semicircular pieces are easier to place and remove than one solid disk.
- Glazed, non-porous surface resists absorbing flavors and odors.

How We Picked the Best Fermentation Weights Under 100
We focused on the factors that matter most for home fermentation: jar compatibility, weight and stability, ease of handling, cleaning convenience, and value per piece. The selection includes compact glass weights for regular wide-mouth Mason jars, larger options for gallon jars, ceramic crock-style weights, and multi-packs for frequent fermenters.
Because product specifications can vary, confirm the listed diameter and intended jar size before ordering. A weight that fits a standard wide-mouth jar may not work with a narrow-mouth jar or a larger fermentation crock.
Quick Comparison
| Best For | Recommended Style | Why It Stands Out |
|---|---|---|
| Occasional small batches | Two- or four-piece glass set | Lower upfront cost and easy storage |
| Frequent fermenting | Multi-pack glass set | Supports several jars at once |
| Large batches | Gallon-jar or crock weight | Designed for greater volume and wider openings |
| Easy handling | Glass weight with lift handle | Simpler placement and removal |
Key Buying Factors for Fermentation Weights Under 100
Fit and Diameter
Start with the opening of your jar or crock. Most options in this roundup are made for wide-mouth Mason jars, but diameters differ. Measure the inside opening and compare it with the product specifications. The weight should sit securely without being difficult to remove.
Material and Weight
Food-contact glass is popular because it is nonporous, reusable, and generally easy to clean. Ceramic weights can work well in crocks and larger vessels, but their shape and size may make them less versatile for standard jars. A heavier weight can be useful for dense or buoyant vegetables, provided it fits properly.
Handles and Cleaning
Easy-grip handles make it easier to lower a weight into a packed jar and remove it after fermentation. Dishwasher-safe designs can simplify cleanup, although you should still follow the manufacturer’s care instructions and inspect each piece for chips or cracks.
Pack Size and Value
Choose a two-pack if you usually ferment one or two jars at a time. Four-piece and nine-piece sets offer better flexibility for larger batches, recipe testing, or keeping spare weights available. Compare usable pieces rather than package size alone.
Who Should Buy Which Fermentation Weights Under 100?
Choose a compact glass set if you make occasional sauerkraut, pickles, kimchi, or vegetables in standard wide-mouth jars. These sets are usually the simplest and most versatile starting point.
Choose a larger multi-pack if you ferment several jars at once or want matching weights for repeat batches. The higher piece count can provide better value when all the weights will be used regularly.
Choose a gallon-jar or ceramic crock weight if you work with larger batches. Verify the vessel dimensions carefully, since oversized weights may not fit standard Mason jars.
Whichever style you select, pack the vegetables firmly, keep them below the brine, and check the ferment periodically. Replace any weight that develops cracks, chips, or other damage.
