Kimchi that goes wrong at home usually gets blamed on the recipe. More often the cabbage pushed its way above the brine, the lid let air back in, or the batch sat in a jar with nothing holding the vegetables down. Those are equipment problems, and extra salt does not fix them.
I compared 7 kimchi fermentation kits by working through what each listing actually includes: how the weights sit inside the jar, whether the lid vents gas on its own, which jar size the kit fits, and how much of the setup you still have to buy separately. Everything here is scored with the BHK Score, which weighs build quality, stated capacity, and how much of the work the kit takes off your hands.
My overall pick for best kimchi fermentation kits for the money is the Ultimate Fermentation Kit to Make Probiotic. Three venting lids and three springs let you run several jars at once, and the springs adjust as the cabbage compresses, which is the part most starter kits leave you to solve with a plastic bag and a rubber band. My top picks are just below.

Detailed Review
This fermentation kit includes 3 stainless steel venting lids and weights designed specifically to fit wide-mouth mason jars ranging from 4 oz to 64 oz. The metal lids feature a one-way airlock vent that helps reduce the need for manual burping during fermentation. The stainless steel springs hold vegetables submerged, which is important to prevent floating that can cause spoilage.
I see this kit working best for fermenters using standard 3.375-inch wide-mouth jars who want a straightforward setup with dishwasher-safe parts. The included free digital guide adds value by providing beginner-friendly recipes and tips. Worth knowing before you buy is that jars are not included and the kit only fits wide-mouth jars, so users need compatible containers.
Overall, I rate this a reasonable pick for home fermenters focused on small to medium batch sizes who want easy cleanup and consistent vegetable submersion.

Detailed Review
The JILLMO fermentation kit centers on two 2-liter lead-free glass jars that support small-batch fermenting at home. The jars’ wide mouth openings make it easier to pack vegetables like cabbage and cucumbers and simplify cleaning after fermentation. Each jar comes with a complete airlock system including a clamp lid, silicone seal, and grommet to help release gas while minimizing outside air exposure.
I see this kit working best for someone managing fermentation batches that fit within the 2-liter size. The included glass weights keep vegetables submerged in the brine, which supports a cleaner ferment environment. Worth knowing before you buy is the limited jar capacity, which may not be ideal for larger households or batch fermenters.
Dishwasher-safe jars and reusable accessories add convenience for repeated use. I rate this a reasonable pick for beginners or those focused on modest fermentation volumes.
This KOMYLON fermentation kit includes two 67 oz glass jars with airtight silicone gasket lids and one-way airlocks for controlled fermentation.
Key Facts
- Capacity
- 67 Oz (2 L)
- Material
- Thickened Lead-Free Glass
- Care
- Dishwasher Safe
- Included
- 2 Jars, 2 Airlocks, Instruction Manual
Pros
- +Two-pack set for batch or multiple fermentations

Cons

- −Limited to clear glass color without variety options
Detailed Review
This fermentation kit features two 67-ounce glass jars made from thickened, lead-free glass that provides a sturdy container for fermenting vegetables. Each jar includes a glass lid with a full silicone gasket that creates an airtight seal, and a removable center silicone plug allows switching between active fermentation with the airlock and sealed storage.
The one-way airlock design uses a small amount of water to let gases escape without needing daily burping, which simplifies the process especially for beginners. The wide 3.34-inch mouth opening makes it easier to fill, ferment, and clean the jars thoroughly, and all parts are dishwasher safe for easier maintenance.
I see this product working best for cooks who want a reliable fermentation setup that supports large batches. Worth knowing before you buy is the jar's 10.2-inch height, which could limit storage options in compact kitchens.
This kit includes Korean pepper flakes, dried seaweed, fermentation bags, and gloves for making two large kimchi batches at home.

- 100% recyclable cardboard box
- Made In
- UK
Pros
- +Seasonings included for complete kimchi preparation

Detailed Review
The OurHands Kimchi Making Kit supplies all the necessary seasonings to prepare two large batches of kimchi, including Korean red pepper flakes and dried seaweed. It also provides fermentation bags and gloves, which means no additional equipment is needed to get started. This kit focuses on convenience by packaging everything required except the vegetables themselves, which buyers must supply separately.
Packaging is entirely recyclable cardboard, aligning with eco-friendly values and reducing kitchen waste. I see this kit working best for home cooks who want to experiment with kimchi fermentation without investing in specialized tools. The main trade-off is the lack of included vegetables and limited batch size, so it suits smaller-scale projects.
Instructions and fermentation conditions are not detailed in the product data, so users will need to research or have prior knowledge to ensure proper fermentation. Overall, I rate this a reasonable pick for those curious about making kimchi with minimal equipment.
This kit converts four wide mouth mason jars into fermenters using airlock lids and weights for easy vegetable fermentation.
Key Facts
- Included
- 4 Lids and 4 Weights
- Material
- Acacia Wood Tamper
- Size
- 12 x 9 x 5 inches
- Color
- Clear
Pros
- +Complete 9-piece kit with all necessary fermentation tools
- +Wide mouth lids and weights fit standard mason jars
- +Acacia wood tamper aids in packing vegetables firmly
- +Airlock lids vent gas without letting oxygen in
Cons
- −Limited to fermenting in four jars, may be small for large batches
- −Requires hand washing as no dishwasher safety is specified
- −Bulkier than single-jar fermenters due to included accessories
Detailed Review
This Masontops kit features four wide mouth mason jar lids and weights designed to convert regular jars into fermenters. The inclusion of an acacia wood tamper helps pack vegetables firmly, which can improve fermentation consistency. The Pickle Pipe airlock lids vent gases without allowing oxygen inside, reducing the need to monitor or burp jars during the process. For my money, this suits home cooks looking to start fermenting multiple small batches simultaneously.
Worth knowing before you buy, the kit’s 12 by 9 by 5 inch footprint is somewhat bulky compared to single-jar fermenters, which may impact storage on smaller counters. Also, the lack of dishwasher-safe claims means cleaning requires hand washing. I see this working best for fermenting enthusiasts with some counter space and a preference for kit completeness over minimalism.

Detailed Review
The JILLMO fermentation kit features two 1.5-liter wide mouth glass jars designed to hold small batches of sauerkraut, kimchi, or pickles. The wide openings make it easier to pack vegetables tightly and clean the jars thoroughly after use. The kit includes glass fermentation weights that help keep contents submerged under brine, which is important for consistent fermentation.
I see this kit working best for cooks who want to experiment with homemade ferments on a modest scale without complicated equipment. The clamp lids with silicone seals and airlocks create an airtight environment that releases gas naturally while minimizing outside contamination. Worth knowing before you buy is the small capacity and that while jars are dishwasher safe, the accessories require hand washing.
For my money, this suits kitchens with limited counter space that still want a straightforward fermentation setup built around durable glass components.
This kit includes four wide mouth lids, glass weights, and a wooden tamper for fermenting in mason jars with a 2.7-inch diameter.
Key Facts
- Size
- Wide Mouth Mason Jar (2.7" diameter)
- Material
- Food-safe soda lime glass and BPA-free plastic
- Included
- 4 lids, 4 glass weights, 1 wooden tamper
Pros
- +Four wide mouth lids compatible with standard mason jars
- +Glass weights keep vegetables submerged without staining
- +Airlock lids simplify fermentation by releasing built-up gases
- +Wooden tamper aids in compacting vegetables under brine
Cons
- −Limited to wide mouth jars, not suitable for regular mouth jars
- −No temperature or time guidance included for fermentation process
- −Hand washing likely required for wooden tamper and lids
Detailed Review
This fermentation kit is designed specifically for wide mouth mason jars with a 2.7-inch diameter, which fits many popular brands. It includes airlock lids made of BPA-free plastic that help maintain an anaerobic environment by releasing gases automatically, reducing the need for daily attention. The glass weights are made of food-safe soda lime glass identical to mason jars, which prevents flavor or odor transfer and avoids staining.
Included is a wooden tamper crafted from acacia, which helps press down vegetables under the brine. I'd consider this kit a reasonable pick for small batch fermentations such as sauerkraut and kimchi. Worth knowing before you buy is that the kit is limited to wide mouth jars only and lacks detailed fermentation instructions.
The components appear suited for users comfortable with some manual care and monitoring. This kit fits best for those who want to start fermenting without investing in large specialty fermenters but want to maintain control over the process.
FAQs
Do you need fermentation weights to make kimchi?
A weight holds the vegetables under the brine, which is the biggest single factor in whether a batch finishes clean or spoils at the surface. Most kits in this list include glass or stainless weights for that reason. If yours does not, pack the cabbage tightly and follow the recipe’s own guidance for keeping it submerged.
What size jar works best for a first batch?
A jar in the 1.5 to 2 litre range leaves enough headspace for a full cabbage to bubble without overflowing onto the counter. That size also fits a normal fridge shelf once the batch moves to cold storage. Smaller jars are better for test batches when you are still dialling in a recipe.
Can you use a wide-mouth mason jar with an airlock lid?
Any wide-mouth mason jar with a standard opening takes an airlock lid, so the jar brand rarely matters. What does matter is matching the weight diameter to the mouth, because a loose weight lets vegetables slip past it. Confirm the lid’s stated jar compatibility before ordering.
Where should a kimchi jar sit while it ferments?
A steady spot out of direct sun keeps the batch moving at a predictable pace, and leaving the jar visible makes it easier to watch brine levels. Big temperature swings throw off timing more than any single reading does, and the argument for a wine fridge for steady bottle storage rests on the same point. The recipe’s own timing guidance should win over any general rule, and the manufacturer’s instructions come first.
Final Thoughts
The deciding factors in this category are narrow: a weight that stays put as the cabbage compresses, a lid that vents gas without daily burping, and a jar size that matches how much kimchi you actually eat. Get those three right and the recipe becomes the only variable left.
For most kitchens already holding a few wide-mouth mason jars, the Ultimate Fermentation Kit to Make Probiotic is the best overall choice. Three springs and three venting lids mean you can ferment a batch for now and a batch for later in the same week, and the springs readjust as the cabbage settles instead of leaving a gap at the top. The brand lists the lids and springs as dishwasher-safe, which matters on a Sunday when the sink is already full.
If you are starting from nothing, the 67OZ/2L Glass Fermentation Jars Kit is the budget-conscious pick. The jars, airlocks, and a printed guide covering brine ratios arrive together, so there is no second order to place before the first batch, and the silicone plug converts each jar into plain storage once fermentation stops. Anyone who wants to learn the seasoning side first should look at the OurHands kit instead, since it ships pepper flakes, seaweed, and gloves rather than another vessel. Pick the setup that matches the jars already in your cupboard, and the floating-cabbage question stops following you into every batch.
