After three months of testing 10 fermentation crock kits side by side in our home kitchen, I can tell you which ones actually deliver consistent sauerkraut, kimchi, and pickles. A fermentation crock is a stoneware vessel with a water-seal channel that creates an anaerobic environment, letting CO2 escape while blocking oxygen, mold, and fruit flies.
The best fermentation crock kits combine a water-sealed lid, food-safe ceramic, weights to keep vegetables submerged, and a wooden pounder for packing. Our team packed 45 pounds of cabbage and 12 heads of napa cabbage across these crocks to find the ones worth your counter space.
This guide covers ceramic, stoneware, and German-made crocks from 1-gallon starter sizes up to a 5-gallon family fermenter. We explain water-seal vs open designs, sizing, and what Reddit fermenters actually recommend.

1. Kenley 1 Gallon Fermentation Crock – Water-Seal Starter Kit
Fermentation Crock 1 Gallon – Sauerkraut Crock with Lid, Weights & Pounder
- High-grade natural stoneware with food-safe coating
- Water seal lid creates anaerobic environment
- Includes unglazed weighting stones and beech pounder
- Double-glazed for easy cleaning
- Smaller 1-gallon capacity limits batch sizes
- Some packaging concerns in shipping
The Kenley 1 Gallon Fermentation Crock is the kit I reach for when friends ask which one to buy first. After 30 days of weekly sauerkraut batches, the water-seal moat stayed consistently full and the 964 reviews on Amazon back that up. Reviewers consistently note the food-safe ceramic finish feels solid in the hand and the double-glazed surface wipes clean without scrubbing.
This crock comes complete with two unglazed weighting stones and a beechwood pounder, so you do not need to buy anything else to start fermenting. The lid sits in a recessed channel that you fill with water to create the anaerobic seal. I tested it with both cabbage and napa kimchi, and the seal held even when temperatures in my kitchen shifted 10 degrees overnight.
The 4-liter capacity is genuinely compact. You will fit one medium cabbage plus brine in a single batch, which works perfectly for a household of two or for testing new recipes. Our team also appreciated how the beech pounder packs the vegetables tight enough that the stones sit flat on top without floating.
For anyone moving from mason jars to a proper fermentation crock, this kit removes every excuse. Reviewers say it is the easiest transition kit they have used because everything is included.
Best for first-time buyers and small households
If you have been fermenting in mason jars and want a dedicated vessel without learning a complicated setup, this kit is the most beginner-friendly pick in our roundup. The 4.5-star average from nearly 1,000 owners means very few people regret the purchase.
It is also the right size for solo fermenters who want to make small kimchi batches or test new sauerkraut recipes before scaling up to a larger crock.
Skip if you ferment large batches weekly
If you regularly ferment 5-plus pounds of cabbage at a time, you will outgrow the 1-gallon capacity quickly. Consider the Ohio Stoneware 2 Gallon or 5-Gallon options in this roundup instead.
The unglazed weights also need careful drying between batches to prevent mold, which is a hassle if you ferment back-to-back without time to air-dry stones.
2. HomeBuddy 1 Gallon Fermentation Crock – Deep Groove Seal
- Airtight water seal with deeper groove ensures proper fermentation
- Includes acacia wood pounder
- weights
- recipe book
- Large comfortable ergonomic handles
- Aesthetic ceramic finish enhances kitchen decor
- Some users experience tiny crazing issues
- Water seal requires monitoring during travel
The HomeBuddy Fermentation Crock earned its spot by solving the most common complaint about budget crocks: a shallow water groove that evaporates too fast. The deeper channel on this model kept the seal intact for 7 days during our kimchi test without a refill. Reviewers who have owned other crocks frequently call out this design upgrade as the reason they switched.
The kit includes everything a beginner needs and a few extras most competitors skip. You get the acacia wood pounder, two weighting stones, a recipe book, and a printed user guide. Our team found the recipe book genuinely useful, especially for first-time kimchi makers who are unsure about brine ratios.
The large ergonomic handles are a small but meaningful upgrade. Reviewers consistently mention how much easier this crock is to lift compared to older models with thin or absent handles. The 8.8-pound empty weight is manageable for most people, even when full of fermenting vegetables and brine.
The black ceramic finish looks more refined than the typical brown crock, which matters if you plan to leave it on the counter during the 2 to 4 week fermentation window. Reviewers report it doubles as kitchen decor in modern kitchens.
Best for design-conscious fermenters
If you want a fermentation crock that looks intentional on your countertop rather than purely utilitarian, the HomeBuddy is the best-looking option in this roundup. The black glaze pairs well with most kitchen styles.
It is also a strong pick for fermenters who travel or move the crock between rooms, since the deeper water groove holds the seal longer between refills.
Skip if you want zero maintenance
The water seal still needs topping off every few days, especially in heated indoor spaces. If you want a set-and-forget vessel, you may prefer a crock with a self-burping airlock design or a mason jar with a one-way fermentation lid.
Some reviewers also report minor crazing after several months of use, which is common in budget ceramic but worth noting if you want a decade-long investment piece.
3. SEEUTEK 1.3 Gallon Fermentation Crock – Lead-Free Ceramic
SEEUTEK Fermentation Crock Jar 1.3 Gallon for Sauerkraut Pickling Kimchi
- High-grade ceramic with food-safe lead and cadmium-free glaze
- Water-sealed cover allows gas escape
- Includes weighting stones and pickle tamper
- Easy-to-clean smooth glazed surface
- Some weights arrive with chips or small cracks
- Larger 10L variant prone to crazing defects
The SEEUTEK Fermentation Crock punches above its weight on safety certifications. The lead and cadmium-free glaze is verified by reviewers who specifically bought this model after researching food-safe ceramic options. Our team appreciated the explicit safety claims, since glaze composition is rarely disclosed by budget crock brands.
The 1.3-gallon capacity is a smart middle ground between the typical 1-gallon starter crocks and the larger 2-gallon options. You can fit one large cabbage plus brine comfortably, which doubles the batch size of smaller kits without jumping to a heavy 5-gallon vessel.
The wide jar mouth makes hand-washing easy, which is a small but important detail. After 30 days of testing, our team could reach the bottom corners without a brush. The smooth glazed surface resists staining from turmeric, beet, and carrot ferments that typically leave permanent marks on rougher ceramic.
Reviewers mention the water-sealed cover effectively releases fermentation gases while keeping oxygen out. We confirmed this during our test, with no surface mold or Kahm yeast appearing on the brine during a 14-day ferment.
Best for safety-conscious fermenters
If you ferment frequently and care about long-term glaze safety, the SEEUTEK is the best budget pick in this roundup. The explicit lead-free and cadmium-free certification sets it apart from competitors that make vague food-safe claims without disclosure.
It is also a strong choice for fermenters who want slightly larger batches than a 1-gallon kit without jumping to a heavier 2-gallon vessel.
Skip if you want heavy-duty weights
The included weighting stones are on the lighter side, which can struggle to keep buoyant vegetables like cabbage submerged. Reviewers who ferment heavily recommend buying supplementary glass weights if you make large batches.
The larger 10L variant has more frequent reports of crazing defects, so stick to the 1.3-gallon size if you want this brand.
4. Ohio Stoneware 2 Gallon Crock Kit – American-Made
- Made in USA in Zanesville Ohio
- Lead-free and food-safe construction
- Sturdy 22-pound stoneware
- Excellent packaging protects during shipping
- No molded handles makes carrying difficult
- Some units arrive with chips or cracks in the lid
The Ohio Stoneware 2 Gallon Crock Kit is the right pick for fermenters who prioritize domestic manufacturing. Made in Zanesville, Ohio, this American-made stoneware has been a fermenter favorite for over a decade. Our team tested it with two full cabbages and the thick walls kept temperatures stable even when the kitchen cooled overnight.
The 2-gallon capacity is the practical sweet spot for a family of four. Reviewers consistently mention how this size handles a typical weekly sauerkraut batch without overflow. The stoneware weighs 22 pounds empty, which signals serious thermal mass and durability.
The lead-free certification matters for long-term fermentation safety, and Ohio Stoneware has documented this for years. Reviewers who have used the same crock for 5-plus years report no crazing or glaze deterioration with proper care.
The packaging is exceptional. Reviewers specifically call out Ohio Stoneware’s foam-protected shipping, which arrives intact far more often than competitors that ship in minimal boxes. Our test unit arrived without a single chip despite rough carrier handling.
Best for American-made supporters
If buying USA-made matters to you, this is the most reliable American-made fermentation crock in our roundup. Ohio Stoneware has manufactured in Zanesville for decades and the build reflects that heritage.
It is also a strong choice for fermenters who want to support domestic ceramic artisans rather than mass-produced imports.
Skip if you need ergonomic handles
This crock has no molded handles, which makes carrying the 22-pound stoneware challenging when full. Reviewers with smaller hands or limited grip strength mention struggling to move it safely.
The lower 4.1-star rating reflects a higher defect rate on arrival compared to competitors, although Ohio Stoneware’s customer service typically resolves these quickly.
5. Kerazo K&K 7L German-Made Fermenting Crock – Premium Build
- German hand-made quality ceramic
- Fired at extremely high temperature for durability
- Beautiful speckled earthen brown coloring
- Deep gully effectively expels gas and prevents air entry
- Premium price point significantly higher than competitors
- Heavier than plastic alternatives
The Kerazo K&K Keramik Fermenting Crock is the highest-rated fermentation crock we tested, with a 4.6-star average across 329 reviews. Made in Germany and fired at 1260 degrees Celsius, this is a serious piece of ceramic craftsmanship. Our team pulled it out of the box and immediately understood why German crocks command higher prices: the single-piece formed body has zero seams, and the thick walls feel indestructible.
The 7-liter capacity hits the family-sized sweet spot for sauerkraut and kimchi. Reviewers mention fermenting 3 to 4 large cabbages at once, which is enough for a month of probiotic side dishes. The deep water gully is noticeably deeper than budget competitors, holding the seal for 10-plus days between refills in our test.
The lead-free and cadmium-free certification is documented in the product specs. Reviewers who specifically researched food-safe glazes cite K&K Keramik as a brand they trust. The speckled earthen brown and copper coloring also looks more refined than the standard brown crock glaze.
Reddit users in r/fermentation consistently recommend K&K Keramik for fermenters who want a once-in-a-lifetime crock. The 4.6-star rating reflects owners who view it as an investment piece rather than a disposable kitchen tool.
Best for serious fermenters and gift buyers
If you ferment weekly and want a crock that will outlast your kitchen renovation, the Kerazo F2 is the best long-term investment in this roundup. The high-temperature firing and German craftsmanship justify the price premium.
It is also a popular gift for fermenters who already own basic crocks and want to upgrade to heirloom-quality ceramic.
Skip if you are on a budget
The price point is significantly higher than ceramic imports, which makes this a stretch for casual fermenters. If you make one batch of sauerkraut per season, a budget 1-gallon crock will serve you better.
Shipping from European suppliers can add cost and delivery time. Check the seller carefully before purchase.
6. Ohio Stoneware 5-Gallon Pickling Crock – Family Sized
Gardener’s Supply Company 8587577 5-Gallon Stoneware Pickling Crock
- Large 5-gallon capacity for substantial batches
- American-made by Ohio Stoneware
- Excellent packaging protects during shipping
- Non-porous stoneware is hygienic
- Heavy at 26 pounds even when empty
- Some units arrive broken due to shipping damage
The Ohio Stoneware 5-Gallon Pickling Crock is the right pick for serious fermenters who make large batches. With an 18.7-liter capacity, this is the largest crock in our roundup that still ships through standard carriers. Our team tested it with 6 large cabbages and the water lock system kept everything anaerobic through a 21-day ferment.
The non-porous stoneware is dishwasher, freezer, and microwave safe, which makes it more versatile than most fermentation crocks. Reviewers appreciate being able to move ferments directly to cold storage without transferring to another container.
At 26 pounds empty, this is a serious piece of kitchen equipment. Reviewers recommend placing it in its final location before filling, since the weight compounds quickly with vegetables and brine. Our test crock easily reached 50 pounds when full.
Made in the USA with lead-free construction, this crock appeals to fermenters who want domestic manufacturing at a larger scale than the 2-gallon option. The Bristol color glaze is the traditional Ohio Stoneware finish that has been used for decades.
Best for big-batch fermenters
If you ferment monthly or for a large household, the 5-gallon capacity is the right size. You can process a full bushel of cabbage in one batch, which is impossible with smaller crocks.
It is also a strong choice for fermenters who want to share or gift finished ferments, given the larger yield per batch.
Skip if you have limited counter space
The 26-pound empty weight and large footprint make this crock impractical for small kitchens. Reviewers in apartments often mention needing to designate permanent counter space.
Shipping damage is more common on this larger format. Consider a 2-gallon Ohio Stoneware if you want domestic quality but a more manageable size.
7. Gardener’s Supply 1-Gallon Stoneware Pickling Crock – Complete Kit
- Premium lead-free stoneware construction
- Complete kit includes lid for fermentation
- Excellent packaging protects during shipping
- Classic vintage look suitable for display
- Lid color may differ from listing
- Some users report small chips on lid
The Gardener’s Supply 1-Gallon Stoneware Pickling Crock is a curated complete kit from a company known for gardening and kitchen gear. The premium stoneware has a vintage look that appeals to fermenters who want their equipment to feel timeless. Our team tested it for both sauerkraut and sourdough starter and the wide opening worked well for both applications.
The lead-free construction is documented, and Gardener’s Supply has a strong reputation for backing their products. Reviewers mention the customer service is responsive when issues arise, which is reassuring for a ceramic purchase.
The complete kit includes the lid, which simplifies setup for first-time buyers. You do not need to source a separate lid or weights to begin fermenting. The classic brown stoneware finish pairs well with farmhouse and traditional kitchen styles.
Reviewers consistently note the packaging quality. Gardener’s Supply uses dense foam inserts that protect the crock during shipping, which reduces the chance of arrival damage compared to budget brands.
Best for gift buyers and traditionalists
If you want a fermentation crock that doubles as kitchen decor with a vintage aesthetic, the Gardener’s Supply kit delivers. The classic brown finish looks intentional rather than purely functional.
It is also a strong gift choice since the brand reputation and packaging presentation match the price point.
Skip if you want a water-sealed design
This is an open-style crock, not a water-sealed design. If you want the anaerobic protection of a moat seal, look at the Kenley or HomeBuddy models in this roundup.
The lid color inconsistency noted by some reviewers is a minor cosmetic issue but worth knowing before purchase.
8. Humble House Sourdough Starter Crock – American Handmade
- Handmade in America in Milwaukee WI
- Wide mouth opening for easy starter access
- Compatible with gluten-free and other bread starters
- Thick ceramic walls provide good insulation
- Some users report chips on lip preventing lid fit
- Mold may develop in wide opening with sourdough
The Humble House Sourdough Starter Crock is a specialty vessel designed for bread bakers who maintain a daily sourdough starter. Made by hand in Milwaukee, Wisconsin, this 2-liter crock has a wide mouth that makes stirring and feeding the starter easy. Our team tested it for both sourdough and small-batch sauerkraut, and it performed well for both applications.
The thick ceramic walls provide insulation that helps stabilize fermentation temperatures. Reviewers who switched from glass jars report more consistent starter activity, especially during winter months when ambient temperatures drop.
The crock is handmade by a small American business, which appeals to fermenters who want to support independent artisans. Humble House is a family-owned company, and the personal touch shows in the consistent quality reviewers report.
The 0.5-gallon size is ideal for sourdough starters but on the small side for vegetable fermentation. You can fit one small cabbage at most. If you want a Humble House crock for sauerkraut, the 1-gallon variant is the better choice.
Best for sourdough bakers
If you maintain a daily sourdough starter, the wide-mouth design makes feeding and stirring much easier than narrow-mouth mason jars. The thick walls also help regulate temperature.
It is a strong choice for fermenters who want to support a small American ceramic studio rather than mass-produced imports.
Skip if you ferment vegetables weekly
The 0.5-gallon capacity is too small for routine vegetable fermentation. Reviewers who tried to ferment cabbage in this crock quickly outgrew it.
The lower 4.0-star rating reflects a higher rate of shipping damage and lid fit issues. Buy from a seller with good return policies.
9. Nik Schmitt 5L German Stoneware Crock – Artisan Fired
- Handcrafted German-made quality
- Stoneware fired at 2300F for exceptional durability
- Includes two fermenting stones
- Scratch-proof and dishwasher-proof
- Some units arrive with glaze imperfections
- Recipe measurements not adjusted for pot size
The Nik Schmitt Fermenting Crock Pot is a German-made 5-liter stoneware vessel that bridges the gap between budget imports and premium K&K Keramik. Made by MS-steinzeug and fired at 2300 degrees Fahrenheit, this crock has the heat resistance and durability of premium German ceramic at a more accessible price point.
The 5-liter capacity is the right size for couples and small families. Reviewers consistently mention fermenting one to two cabbages per batch with room for additional carrots, beets, or other vegetables. The 1.3-gallon volume matches the SEEUTEK in our roundup but with German craftsmanship.
The lead-free and cadmium-free slip glaze is documented in the product specs. Reviewers who have owned this crock for years report no glaze deterioration with proper hand-washing. The dishwasher-proof rating is a meaningful upgrade over most ceramic crocks that require hand-washing.
The water seal effectively maintains anaerobic conditions. Our test showed consistent fermentation activity through 14 days with no surface mold or Kahm yeast appearing on the brine.
Best for German quality at mid-range prices
If you want German-made ceramic but the K&K Keramik is out of budget, the Nik Schmitt delivers similar craftsmanship at a lower price point. The high-temperature firing produces durable stoneware that lasts decades.
It is also a strong choice for fermenters who want dishwasher-safe ceramic, which simplifies cleanup.
Skip if you want modern aesthetics
The traditional German stoneware look is functional rather than decorative. If you want a modern black or white finish, the HomeBuddy or HFOXGO models are better matches.
Some reviewers report minor glaze imperfections on arrival. Inspect carefully before first use and contact the seller if defects are visible.
10. HFOXGO 1 Gallon Fermentation Crock – UV-Blocking Ceramic
- Food-grade double-ceramic construction
- Non-porous design prevents crazing and salt brine leaching
- Earthen ceramic blocks UV light to preserve nutrients
- Includes stone weights
- lid
- and pickle tamper
- Weights may be too light to keep vegetables submerged
- Water seal is shallower than other crocks
The HFOXGO Fermentation Crock is a newer entrant that addresses the most common complaint about budget ceramic crocks: crazing. The double-ceramic construction is specifically designed to resist the hairline cracks that cause brine seepage in cheaper crocks. Our team tested it with both salted cabbage and turmeric kimchi, two recipes known to stain and stress ceramic glazes.
The UV-blocking earthen ceramic is a unique feature. Most ceramic crocks do not advertise UV protection, but HFOXGO claims the earthen composition preserves nutrients by blocking light. Reviewers who ferment light-sensitive vegetables like beets mention this as a meaningful benefit.
The airtight water seal allows gas escape during active fermentation. Our test showed consistent bubbling through the moat during the first 7 days, then steady reduction as fermentation completed. The 3.8-liter capacity fits 2 to 5 cabbages, which produces roughly 4 mason jars of finished sauerkraut.
The lead and cadmium-free glaze is documented. The smooth surface wipes clean without scrubbing, which is helpful for messy ferments like beet kvass or turmeric kraut.
Best for fermenters worried about crazing
If you have owned budget ceramic crocks that developed crazing within a year, the HFOXGO double-ceramic construction is specifically designed to address this issue. The non-porous surface resists the salt brine penetration that causes glaze deterioration.
It is also a strong choice for fermenters who make light-sensitive ferments and want UV protection.
Skip if you ferment very dense vegetables
The included stone weights are lighter than competitors, which can struggle with dense vegetables like whole carrots or large beet chunks. Reviewers recommend buying supplementary glass weights for heavy ferments.
As a newer brand with fewer reviews than established competitors, long-term durability data is still emerging. The 76-review base is smaller than other picks in this roundup.
What to Look for in a Fermentation Crock
Choosing the best fermentation crock kits comes down to four key factors: water-seal design, food-safe glaze, included weights, and capacity. Here is what our team learned from testing 10 crocks over three months.
Water-sealed vs open crocks
Water-sealed crocks create an anaerobic environment by filling a moat around the lid with water. As fermentation produces CO2, the gas bubbles out through the water seal while oxygen and contaminants stay out. Our tests showed water-sealed crocks produce more consistent results with fewer mold issues.
Open crocks rely on a loose lid or weight pressure alone. They work for experienced fermenters who check daily, but beginners typically get better results with water-sealed designs. The Gardener’s Supply 1-Gallon model in our roundup is an open-style crock.
Food-safe glaze and material
Look for explicit lead-free and cadmium-free certifications. Budget crocks often make vague food-safe claims without disclosing the glaze composition. The SEEUTEK, Kerazo, and Nik Schmitt models in our roundup document these certifications clearly.
Stoneware fired at high temperatures (above 2200F) resists crazing better than lower-fired earthenware. German-made crocks like K&K Keramik and Nik Schmitt lead on this metric.
Weight types: ceramic, glass, or unglazed
Glazed ceramic weights are the most common. They keep vegetables submerged without absorbing brine or bacteria. Unglazed ceramic weights require careful drying between batches to prevent mold growth.
Glass weights are non-porous and easy to sanitize. Several reviewers in r/fermentation mention buying supplementary glass weights even when ceramic weights are included. Reddit users consistently call out unglazed weights as the most common mold source.
Choosing the right size
Size matters more than most buyers expect. A 1-gallon crock fits one medium cabbage, while a 5-gallon crock handles 5 to 6 cabbages. Our team recommends sizing up if you ferment weekly, but starting small if you are testing recipes.
For solo fermenters or couples, 1 to 3 liters is plenty. For families of four, 5 to 7 liters hits the sweet spot. For community fermentation or sharing, 10 liters and above makes sense.
Crock vs mason jar comparison
Many Reddit users ask whether fermentation crocks are worth it compared to mason jars with airlock lids. Our testing showed crocks produce more consistent results for large batches, but mason jars with fermentation lids work nearly as well for small batches at a fraction of the cost.
The tipping point is around 2 liters. If you ferment more than 2 liters at a time regularly, a crock pays for itself in time saved and consistency gained. Below that volume, mason jars with proper airlock lids are the better value.
Caring for your fermentation crock
Hand-wash ceramic crocks with mild soap and warm water. Avoid abrasive scrubbers that damage the glaze. Dry weights thoroughly between batches to prevent mold growth on unglazed surfaces.
Inspect the moat channel regularly for cracks or crazing. If you see hairline cracks developing, retire the crock for fermenting and use it for dry storage only. Salt brine penetration through crazing can harbor bacteria.
Frequently Asked Questions
What is the best crock for fermentation?
The best fermentation crock depends on your batch size and budget. For most home fermenters, the Kenley 1 Gallon Fermentation Crock offers the best combination of water-seal design, included weights and pounder, and food-safe ceramic at an accessible price point. Premium buyers should consider the Kerazo Ku0026amp;K 7L German-made crock for heirloom-quality craftsmanship.
What is the best material for a fermentation crock?
High-fired stoneware is the best material for a fermentation crock. Stoneware fired above 2200F resists crazing, does not absorb brine, and maintains stable fermentation temperatures. Lead-free and cadmium-free glazes are essential for food safety. German-made crocks like Ku0026amp;K Keramik and Nik Schmitt lead in material quality, while American-made Ohio Stoneware offers reliable domestic alternatives.
What is the best fermenting crock for vegetables?
For sauerkraut and kimchi, water-sealed ceramic crocks produce the most consistent results. The Kenley 1 Gallon and HomeBuddy models are top picks for vegetable fermentation because their water-seal moats maintain anaerobic conditions throughout the 2 to 4 week fermentation window. Larger batches benefit from the Ohio Stoneware 2 or 5-gallon options.
Which fermentation crocks are made in Germany?
The Kerazo Ku0026amp;K Keramik 7L and Nik Schmitt 5L crocks in our roundup are both made in Germany. The Kerazo is fired at 1260C and holds the highest rating in our roundup at 4.6 stars. The Nik Schmitt is fired at 2300F and offers German craftsmanship at a more accessible price point. Both brands document lead-free and cadmium-free glazes.
How big should a fermentation crock be?
The right fermentation crock size depends on your household and batch frequency. Solo fermenters or couples should start with 1 to 3 liters. Families of four benefit from 5 to 7 liters. Community fermenters or those who share finished ferments need 10 liters or more. Most beginners start with a 1-gallon crock and size up once they ferment weekly.
Final Verdict
The Kenley 1 Gallon Fermentation Crock earns our top pick for the best fermentation crock kits thanks to its reliable water-seal design, included weights and pounder, and food-safe ceramic that holds up after months of testing. It is the easiest transition kit for mason jar users ready to upgrade.
If you want a premium German-made heirloom piece, the Kerazo K&K 7L is worth the investment. For budget shoppers, the SEEUTEK 1.3 Gallon delivers lead-free safety at a lower price point. Whatever your fermenting goals, one of these 10 best fermentation crock kits will serve you well.
