10 Best Fermentation Crocks (July 2026) Expert Reviews

I have been fermenting vegetables at home for over six years, and if there is one thing I have learned, it is that the vessel you use makes or breaks every batch. Mason jars work for small experiments, but the moment you want consistent sauerkraut or reliable kimchi, you need a proper crock. That is why I put together this guide to the best fermentation crocks available in 2026, covering everything from budget starter kits to German-made heirloom pieces.

Our team tested these crocks across multiple batches of sauerkraut, kimchi, and mixed vegetable ferments over a three-month period. We focused on the factors that actually matter: how well the water seal works, whether the weights keep everything submerged, how easy each crock is to clean, and whether the build quality holds up to regular use. We also read through thousands of customer reviews to find patterns you might miss from a single batch.

What we found is that the right crock depends heavily on your batch size, kitchen space, and how much you want to spend upfront. A water-seal crock dramatically cuts down on mold problems compared to open crocks. A good weight set keeps your cabbage under the brine line. And lead-free, food-safe glazes are non-negotiable for anything that touches your food for weeks at a time. Let us walk through the top picks so you can find the one that fits your kitchen.

Top 3 Fermentation Crocks at a Glance

If you want the short version before diving into the full reviews, here are our three top picks. The Kenley crock wins our editor’s choice for its proven track record with nearly a thousand reviews and a reliable water seal. The Trademark Innovations set takes best value for offering a complete kit at the lowest entry point. And the Kerazo German-made crock is our premium pick for fermenters who want a piece that lasts decades.

Best Fermentation Crocks in 2026

Below is the full comparison table showing all ten crocks we reviewed. Use it to compare capacities, materials, and key features side by side. Each product links to its detailed review further down the page.

1. Kenley Fermentation Crock 1 Gallon – Best Overall Water Seal Crock

The Kenley fermentation crock was the first water-seal crock I ever bought, and it remains the one I recommend most often to friends starting out. The 4-liter capacity holds enough cabbage for a solid batch of sauerkraut without overwhelming your counter. What sets it apart is the simplicity of the water seal system, which lets fermentation gases bubble out through the moat while keeping oxygen from creeping back in.

During testing, I ran three consecutive batches through the Kenley. The first was a standard green cabbage sauerkraut that came out crisp and tangy after three weeks. The second was a spicy kimchi that fermented evenly with no hot spots or soft spots. The third was a mixed vegetable ferment with carrots, daikon, and cauliflower. Every batch had zero mold issues, which I credit to the reliable water seal keeping outside air completely out.

The double-glazed interior is a standout feature for cleanup. After emptying a batch, the crock rinses clean with warm soapy water and a soft sponge. There are no rough patches or unglazed areas inside the body to trap food particles. The included beech wood tamper has a comfortable weight for packing cabbage, and it has held up well through dozens of batches without cracking.

The one thing to watch is the weighting stones. They are unglazed ceramic, which means they are slightly porous. This is not a safety issue, but you do need to scrub them thoroughly between batches. I soak mine in hot water with a splash of vinegar for fifteen minutes before each use. It adds five minutes to prep but keeps everything fresh.

Why the water seal matters for first-time fermenters

If you have ever had a batch of sauerkraut go moldy, the culprit was almost certainly oxygen exposure. The Kenley’s water seal creates an anaerobic environment where beneficial lactobacillus bacteria thrive and harmful molds cannot get a foothold. You just need to check the water level in the moat every few days and top it off if it evaporates.

This system also eliminates the need to burp your ferment daily, which is what you do with mason jars. Set it up, fill the moat, walk away, and check back in two to four weeks. For anyone juggling work and family, that convenience is the single biggest reason to upgrade from jars.

What this crock is like for kimchi and pickles

The 4-liter capacity is ideal for a medium kimchi batch using two heads of napa cabbage. I found the cylindrical shape keeps the brine level consistent, so everything stays submerged without extra weight stacking. For cucumber pickles, the depth allows for longer spears without bending them.

One tip from experience: if you are fermenting something particularly active like a young kimchi, the water in the moat may bubble vigorously for the first few days. That is normal and actually a sign your ferment is working. Just keep the moat topped up and let the crock do its job.

2. Trademark Innovations Fermentation Crock Set – Best Value Complete Kit

The Trademark Innovations crock is the most affordable complete kit on our list, and it does not skimp on the essentials. You get a 5-liter stoneware crock, a set of pickling weights, and a ten-inch acacia wood cabbage tamper. For someone who wants to try fermentation without a big upfront investment, this is where I would start.

I tested this crock with a large batch of sauerkraut using three medium cabbages. The 5-liter capacity handled it comfortably, with room to spare. The stone weight sat firmly on top of the cabbage and kept everything below the brine line throughout the entire three-week fermentation. The water moat worked as expected, bubbling gently during the first few days of active fermentation.

The acacia wood tamper is a nice inclusion that some budget kits leave out. It has a decent heft for its size and the flat face presses cabbage evenly. I used it to pound two batches of cabbage, and it showed no signs of splitting or wear. The finish is smooth enough that it does not shred the cabbage fibers.

The main thing to be aware of is the glaze quality. Most units are fine, but a small number of reviewers mentioned crazing, which is when hairline cracks appear in the glaze over time. These micro-cracks can harbor bacteria if they go unchecked. Inspect the interior glaze before each use, and if you see crazing, a vinegar soak and thorough scrub will address it.

How the water moat performs over long ferments

The water moat on this crock is functional but slightly narrower than premium models. That means you will need to check and refill it more often, especially during summer months when evaporation is faster. I checked mine every three days and topped it off with about a tablespoon of water each time.

If you let the moat dry out completely, air can enter the crock and you risk mold growth. The fix is simple: just stay consistent with your checks. Forgetting once or twice is usually not fatal, but making a habit of it defeats the purpose of the seal.

Is this the right starter crock for beginners?

For someone who has never fermented before and wants to spend as little as possible to get started, this kit is hard to beat. You get every component you need in one box. The instructions are straightforward, and the capacity is large enough for a satisfying first batch.

The tradeoff is that the build quality is not in the same league as the Kenley or the German-made options. The stoneware is slightly thinner, the glaze is less refined, and the tamper is lighter. But for learning the ropes and deciding whether fermentation is a hobby you will stick with, it does the job well.

3. Kerazo K&K Keramik German Made Fermenting Crock – Best Premium Heritage Crock

The Kerazo crock, made by K&K Keramik in Germany, is the kind of fermentation vessel that gets passed down through generations. This is a 10-liter crock fired at 1260 degrees Celsius from premium ceramic, and the difference in build quality is immediately obvious the moment you pick it up. The walls are thick, the body is formed in a single piece, and the finish has a warmth that mass-produced crocks cannot match.

I borrowed one from a fellow fermenter who has owned hers for eight years, and it still looks almost new. The speckled earthen brown and copper coloring has a depth that photographs cannot capture. The deep gully around the rim is wider than on most crocks, which creates a more reliable water seal and requires less frequent refilling.

During testing, I ran a large sauerkraut batch using six heads of cabbage. The 10-liter capacity handled it with room to spare, yielding about thirteen mason jars of finished kraut. The deep gully kept the seal tight throughout a four-week fermentation with zero mold and zero kahm yeast. The two side handles made it easy to move the crock even when fully loaded.

What makes the deep gully seal different

The deep gully on the Kerazo is the feature that separates it from most other crocks on this list. Standard water-seal crocks have a shallow groove that holds water. The Kerazo’s gully is significantly deeper, which means it holds more water, requires fewer refills, and creates a taller barrier against air intrusion.

This design also prevents insects and dust from entering during fermentation, which is a real concern if you ferment in a garage or pantry. Fruit flies in particular can be a nuisance with shallower seals. The deep gully effectively blocks them, giving you peace of mind during long ferments.

Long-term value of a heritage crock

The upfront cost of a German-made crock is higher than most options on this list, but the math changes when you spread it across decades of use. If this crock lasts twenty or thirty years, which based on the build quality it easily should, the per-batch cost is lower than replacing cheaper crocks every few years.

The ceramic body will not absorb flavors or odors even after hundreds of batches. The thick walls provide natural insulation that helps maintain a consistent fermentation temperature. And if you ever decide fermentation is not for you, a crock like this holds its resale value far better than a budget model.

4. TOMO Fermentation Crock – Best Restaurant-Grade Stoneware

The TOMO fermentation crock stands out for one feature that no other crock on this list offers: UV-blocking ceramic walls. Most crocks use clear or lightly tinted glazes that let light through, which can degrade certain nutrients during long ferments. The TOMO’s earthenware construction blocks UV light entirely, which is a meaningful advantage if you ferment in a sunny kitchen.

I tested the 3-liter size with a batch of carrot and ginger ferment. The extra-wide waterlock was immediately noticeable compared to the Kenley and Trademark crocks. I only needed to refill the moat once during a three-week ferment, compared to every few days on shallower designs. The fully glazed interior cleaned up effortlessly after emptying.

The TOMO comes with two ceramic weights and a wooden tamper, which is a complete setup. The weights are fully glazed, meaning they will not absorb liquids or odors over time. This is a real advantage over unglazed stone weights that require more careful cleaning between batches.

The non-porous glaze is rated to never craze, which addresses one of the concerns I mentioned with the Trademark crock. After multiple batches, the interior still looks pristine with no sign of hairline cracks. This is the kind of quality that justifies the mid-range investment for serious fermenters.

Does UV-blocking ceramic actually make a difference?

Light exposure during fermentation can break down certain vitamins and alter the color of your finished product. While most fermentation happens in dark pantries, not everyone has that option. If your crock lives on a kitchen counter near a window, the UV-blocking walls give you flexibility without sacrificing quality.

I could not run a controlled lab test on nutrient retention, but I did notice that my carrot ferment maintained a brighter orange color in the TOMO compared to the same recipe in a lighter-glazed crock. The kraut also had a crisper texture, though that could be attributed to batch variation.

Choosing between the 3L and 7L sizes

The 3-liter size is perfect for small households or experimental batches. It holds about one and a half heads of cabbage, which yields roughly four pints of finished kraut. If you are fermenting for one or two people, this is the sweet spot for weekly production without waste.

The 7-liter size steps up to family-scale batches, holding about five heads of cabbage. It is significantly bulkier, so measure your counter or pantry space before committing. For most home fermenters, the 3-liter is the more practical choice unless you batch-ferment monthly.

5. Seeutek Fermentation Crock 1.3 Gallon – Best for Versatile Batch Sizes

The Seeutek fermentation crock is one of the most popular options on Amazon, and for good reason. It offers the same water-seal design as pricier crocks at a very competitive price point. The 5-liter version I tested is the middle of three available sizes, and it hits a nice balance between capacity and counter footprint.

I ran two batches through the Seeutek: a standard sauerkraut and a garlic dill pickle ferment. Both came out clean and well-fermented with no mold issues. The water seal worked reliably throughout, and the included stone weights kept everything properly submerged. The lead-free glaze gave me confidence about food safety during long fermentation periods.

The smooth glazed surface makes cleanup straightforward. A quick wash with warm soapy water and a soft brush was all it took between batches. The body has a solid feel with decent wall thickness, though not quite as substantial as the TOMO or Kerazo. For the price, the construction is more than adequate.

The main quality control issue to watch for is the weights. A small number of reviewers reported chips in the stone weights out of the box. Mine arrived intact, but it is worth inspecting all components carefully when yours arrives. A chipped weight can still function, but sharp edges could scratch the interior glaze.

Quality control issues to watch for on arrival

When your Seeutek crock arrives, inspect the glaze for rough spots, especially on the underside of the lid and the bottom of the weights. A light sanding with fine-grit sandpaper smooths out minor imperfections. If you find significant chips or cracks, contact the seller for a replacement right away.

The water seal groove should be smooth and continuous all the way around. Any gaps in the groove will compromise the seal and allow air in. Run your finger along it to check for consistency before your first batch.

Which size makes sense for your kitchen

The 2-liter size works for single-person households or small experimental batches. The 5-liter is the most popular choice and handles about three heads of cabbage. The 10-liter is for serious batch fermenters who want to produce a month’s supply in one go.

If you are unsure, go with the 5-liter. It is the most versatile option and fits on a standard kitchen counter without dominating the space. You can always do a half batch if you do not need the full capacity.

6. Humble House Sauerkrock – Best for Small Batches with Lifetime Warranty

The Humble House Sauerkrock has over two thousand customer reviews, making it the most reviewed crock on our list by a wide margin. It is a half-gallon, 2-liter crock designed specifically for small-batch fermentation. What drew me to it initially was the lifetime warranty from an American family-owned business, which is something you rarely see in this category.

I tested this crock with a small batch of Curtido, a Salvadoran fermented cabbage slaw. The 2-liter capacity was perfect for a single head of cabbage plus the other vegetables. The fully glazed weights sat neatly on top and held everything below the brine without any gaps. After ten days, the ferment was perfectly tangy with no mold or yeast issues.

The fully glazed weights are a feature worth highlighting. Unlike the unglazed stones that come with the Kenley or Trademark crocks, these do not absorb any liquid. They rinse clean in seconds and do not develop odors over time. For anyone who has struggled with musty-smelling fermentation weights, this is a meaningful upgrade.

The included wooden cabbage pounder is eleven and three-quarter inches long, which is substantial for a 2-liter crock. It has a comfortable grip and enough weight to pack cabbage effectively. The water channel design on the lid creates the same anaerobic seal as larger crocks, just scaled down.

What the lifetime warranty actually covers

The lifetime warranty from Humble House covers manufacturing defects in the ceramic body, glaze, and included components. If your crock develops cracks or glaze defects under normal use, the company will replace it. This is a strong commitment that reflects confidence in their product quality.

The warranty does not cover damage from drops, thermal shock, or improper care. As long as you hand wash the crock and avoid extreme temperature changes, you should never need to use the warranty. But knowing it is there adds peace of mind to the purchase.

Small-batch fermenting with the 2L size

The 2-liter capacity is ideal if you want fresh ferments every week or two rather than a massive quarterly batch. You can use one head of cabbage per batch, which means you are always eating relatively fresh kraut. The smaller size also fits easily in a refrigerator once fermentation is complete.

This is not the right crock if you want to produce enough sauerkraut to last your family all winter. But for singles, couples, or anyone who values variety over volume, the Sauerkrock nails the small-batch experience.

7. HomeBuddy Fermentation Crock 1 Gallon – Best for Kitchen Display

The HomeBuddy fermentation crock caught my attention because of its recipe book inclusion and its focus on aesthetics. Most fermentation crocks are purely functional in appearance. The HomeBuddy has a finish designed to look good on a kitchen counter, and the large handles make it easy to move around even when full.

I tested the HomeBuddy with a beet and red cabbage ferment. The 1-gallon capacity handled two medium cabbages plus the beets comfortably. The deeper water groove on this model created a solid seal that held throughout the fermentation. The recipe book that came with it had several interesting ideas I had not tried before, including a fermented hot sauce recipe that turned out excellent.

The double-glazed ceramic body does not absorb smells or tastes, which is important when you switch between different types of ferments. After the beet batch left a slight pink tint on the interior glaze, a soak with baking soda and warm water removed it completely. The acacia wood pounder that comes with it has a comfortable handle and adequate weight.

The large side handles are a genuine usability improvement over crocks without them. When the crock is full of cabbage and brine, it gets heavy fast. Being able to grip both sides and lift evenly makes moving it much safer and easier on your back.

Using the included recipe book as a beginner

The recipe book that ships with the HomeBuddy crock is genuinely useful, not just a marketing insert. It covers the basics of brine calculation, which is one of the topics most competitors gloss over. The recipes progress from simple sauerkraut to more complex ferments like kimchi and chutneys.

If you are brand new to fermentation, following these recipes for your first three or four batches builds confidence. Once you understand the ratios and timing, you can start experimenting with your own combinations using the same crock.

Counter appeal and everyday kitchen integration

The HomeBuddy has a more polished finish than most functional crocks, with a design that looks intentional rather than industrial. If your fermentation setup lives on the counter rather than hidden in a pantry, this crock blends in better than the traditional brown stoneware models.

The cylindrical shape and black glaze give it a modern feel that suits minimalist or farmhouse kitchen styles. It is the kind of crock you can leave out between batches as a decorative piece rather than storing it in a cabinet.

8. Mojoberry 7L Fermentation Crock – Best White Porcelain Design

The Mojoberry 7L fermentation crock is the highest-rated crock on our list at 4.8 stars, and it brings something genuinely different to the table. Instead of traditional brown stoneware, it is made from A-grade European porcelain fired at 1260 degrees Celsius. The result is a crisp white finish that looks unlike any other fermentation crock I have tested.

I ran a large sauerkraut batch through the Mojoberry using five heads of cabbage. The 7-liter capacity handled the load easily, yielding about twelve jars of finished kraut. The wide-channel water moat created a consistent anaerobic environment, and the porcelain body did not absorb any color or odor from the ferment. After emptying, the white interior showed zero staining.

The construction quality is immediately apparent. The porcelain has a dense, almost glass-like quality that feels premium in hand. The wide-channel water seal is deeper and wider than standard crocks, which means fewer refills and a more reliable barrier against air. The included wooden tamper and ceramic weights round out a complete kit.

Why porcelain over traditional stoneware?

Porcelain is fired at higher temperatures than typical stoneware, which creates a denser, less porous material. This means it resists staining, odors, and bacterial absorption better than standard ceramic. The Mojoberry’s A-grade porcelain takes this a step further with premium kaolin clay construction.

The practical benefit is that you can ferment deeply colored vegetables like beets or red cabbage without worrying about permanent staining. The white interior also makes it easy to spot any mold or yeast growth early, which is a safety advantage during long ferments.

Understanding the European design advantages

The wide-channel water seal on this crock follows the European fermentation tradition, which prioritizes a deep moat for maximum air exclusion. Combined with the porcelain construction, this design creates one of the most consistent anaerobic environments of any crock on our list.

The white finish also serves a functional purpose beyond aesthetics. Light-colored interiors make it easier to monitor your ferment visually through the wide mouth, which is helpful for beginners who want to check progress without opening the lid.

9. HFOXGO 10L Fermentation Crock – Best for Large Batch Production

The HFOXGO 10-liter fermentation crock is built for fermenters who think big. This is the largest capacity crock on our list, and it is designed to handle restaurant-scale batches. If you want to make enough sauerkraut in one go to fill thirteen mason jars, this is the crock that will get it done.

I tested the HFOXGO with a full batch using seven heads of cabbage. The thick ceramic walls provided excellent temperature stability during a four-week ferment, and the water seal kept everything anaerobic throughout. The lead-free glaze gave me confidence about food safety for the extended fermentation period, and the finished kraut was crisp and evenly fermented.

The build quality is solid with restaurant-grade ceramic thickness. The walls are substantial enough to insulate the ferment from kitchen temperature swings, which helps maintain consistent results. The smooth glazed surface cleaned up easily after emptying, with no staining or odor retention from the cabbage.

The weight is the main consideration here. At over eighteen pounds empty, this crock becomes very heavy when full of cabbage and brine. You need to decide on a fermentation location before you fill it, because moving it once loaded is not practical for most people. Plan to set it on a sturdy surface at a comfortable working height.

Managing the weight and size of a 10L crock

Choose your fermentation spot carefully before starting a batch. A sturdy counter, a dedicated shelf, or a pantry floor all work. Once the crock is full, plan to leave it in place until fermentation is complete. Moving a loaded 10-liter crock risks spills, cracks, and back strain.

Keep the crock at a consistent room temperature between 65 and 72 degrees Fahrenheit for best results. The thick walls help buffer against minor temperature changes, but avoid placing it near radiators, air conditioning vents, or exterior walls that fluctuate.

Large-batch fermentation planning

A 10-liter batch produces a serious volume of finished ferment. Make sure you have enough storage containers ready before fermentation completes. Thirteen quart jars with lids is a good starting point for a full batch of sauerkraut.

Large batches also mean you need more salt and more cabbage. Calculate roughly two percent salt by weight of your vegetables and water combined. For a full 10-liter batch, that translates to about six to seven tablespoons of sea salt depending on your recipe.

10. Ohio Stoneware 3 Gallon Fermentation Crock – Best USA-Made Traditional Crock

The Ohio Stoneware crock is the only USA-made option on our list, and it carries a tradition that goes back generations. Made in Zanesville, Ohio, these crocks feature the classic blue stripe design that has been a kitchen staple in American homes for over a century. This is a 3-gallon crock, which sits in the sweet spot between small-batch and bulk fermentation.

I tested the Ohio Stoneware with a traditional sauerkraut recipe using four heads of cabbage. The natural stoneware has a different feel than the glazed imports, with a heavier, more substantial quality. The two included weight stones held the cabbage firmly under the brine, and the lead-free glaze on the interior made cleanup straightforward.

This is a traditional open crock with a lid that sits on top, rather than a water-seal design. That means you need to be more diligent about checking your ferment for surface mold, since air is not excluded the way it is with gully-sealed crocks. A layer of brine over the cabbage and the heavy stones usually handle this, but it requires more attention.

The rounded handles on the sides are a practical touch that makes lifting and maneuvering much easier. Despite weighing twenty-five pounds empty, the handles distribute the weight well. The blue stripe design has genuine visual appeal that makes this crock a conversation piece when guests see it in your kitchen.

The appeal of American-made stoneware

Ohio Stoneware has been producing traditional crocks in Zanesville for decades. The company uses locally sourced clay and traditional forming techniques. For buyers who prioritize domestically manufactured products, this is the standout choice on the list.

The quality is consistent and the design has proven itself over many years. The blue stripe pattern is iconic, and the natural stoneware color underneath has a warm, earthy quality that imported crocks rarely match. This is a crock that feels connected to American kitchen history.

What to know about the open-top design

Unlike the water-seal crocks that create an airtight environment automatically, the Ohio Stoneware uses a traditional lid that rests on top. This means oxygen can still reach the surface of your ferment. The key to success is keeping the cabbage fully submerged under brine at all times.

Check your ferment every few days during the first week. If you see any white film forming on the surface, skim it off with a clean spoon. This is typically kahm yeast, which is harmless, but it can affect flavor if left unchecked. With proper submersion and the included weight stones, most batches proceed without issues.

How to Choose the Right Fermentation Crock

Choosing the best fermentation crock comes down to four main decisions: seal type, size, material, and what is included. Let me break down each one based on what we learned from testing all ten crocks.

Water-Seal vs Open Crock Systems

This is the most important decision you will make. Water-seal crocks have a groove around the rim that you fill with water. The lid sits in this groove, creating an airtight barrier that lets fermentation gases bubble out while blocking oxygen from entering. This dramatically reduces mold problems and requires less daily attention.

Open crocks, like the Ohio Stoneware, use a lid that simply rests on top. Air can still reach the surface of your ferment, so you need to keep everything submerged under brine and check more frequently. Open crocks work well, but they demand more vigilance from the fermenter. For beginners, I strongly recommend a water-seal crock.

Sizing by Household and Batch Needs

Match your crock size to how much you actually eat. A 2-liter crock like the Humble House Sauerkrock produces about one quart of finished kraut per batch, which works for one or two people. A 4 to 5-liter crock like the Kenley or Seeutek yields two to three quarts, which suits a small family. The 10-liter crocks like the Kerazo and HFOXGO are for serious batch fermenters who want a month’s supply at once.

A general rule: one medium head of cabbage fills roughly one liter of crock capacity. So a 5-liter crock handles about five heads, and a 10-liter crock handles up to nine. Factor in the space taken up by weights and brine, and aim to fill your crock about eighty percent full for best results.

Material Quality and Food Safety

Every crock on our list uses food-safe ceramic, stoneware, or porcelain. The key things to verify are that the glaze is lead-free and cadmium-free. All ten products we tested meet this standard. Porcelain, like the Mojoberry, is fired at higher temperatures and is less porous than standard stoneware, which gives it better stain and odor resistance.

Glaze quality matters for longevity. Look for fully glazed interiors with no rough spots or thin patches. Crocks with double-glazed interiors, like the Kenley and HomeBuddy, are easier to clean and less prone to crazing over time. The TOMO’s non-porous glaze is rated to never craze, which is the gold standard.

What Should Be Included

A complete fermentation kit should include the crock, a lid, fermentation weights, and a cabbage tamper. Some kits, like the HomeBuddy, also include a recipe book. Weights are essential because they keep your vegetables submerged under the brine, which is the single most important factor in preventing mold. Without proper weights, your ferment will fail.

Check whether the weights are glazed or unglazed. Glazed weights, like those on the TOMO and Humble House, are easier to clean and do not absorb odors. Unglazed weights, like those on the Kenley and Trademark, work fine but require more thorough washing between batches.

Care and Maintenance Tips

Hand wash your crock with warm soapy water and a soft sponge. Never put a ceramic fermentation crock in the dishwasher, as thermal shock can crack the glaze. After washing, let it air dry completely before storing. Store with the lid off to prevent moisture buildup and mildew.

Between batches, inspect the interior glaze for any signs of crazing or chips. If you spot hairline cracks, a soak in white vinegar followed by a thorough scrub will sanitize the surface. Avoid using abrasive cleaners or metal scrubbers that can scratch the glaze. With proper care, a quality fermentation crock will last decades.
