Best Fermentation Crocks

The Spruce Eats / Lecia Landis

Fermenting is an ancient food preservation technique that has recently experienced a widespread resurgence in popularity, in part due to the many health benefits of fermented foods. It’s easy to ferment your own sauerkraut, kimchi, pickles, olives, hot sauce, and more at home. Lacto-fermentation requires nothing more than fresh produce, salt, and water because it relies on sugars and bacteria naturally present in these foods. While the process is simple, it helps to have the right tools. You’ll need a large, wide-mouthed container and something to weigh down your ingredients to make sure they stay submerged in their brine as they ferment and pickle. 

The most traditional type of container used for fermenting is a ceramic crock, and there are two main types available: water-sealed or open. The lid of water-sealed crocks sits in a shallow “moat” around the mouth of the crock. Straight-walled open crocks are sold with or without a lid and weights. Each type has its pluses and minuses, and there are many options available. Here are our top picks to help you narrow down the choices and find the best setup for your fermenting needs.

What Our Experts Say

"Modern fermentation crocks come in so many styles and sizes. My grandparents kept a giant open crock on the back porch and fermented sauerkraut for the whole family. That's still an option, but I like crocks small enough that they can rest on the countertop or table in my kitchen." Julie Laing, Canning and Fermenting Expert, Author of "The Complete Guide to Pickling"

Best Overall, Water-Sealed

Kenley Fermentation Crock 5 Liter and Pounder

Kenley Fermentation Crock 5 Liter and Pounder


What We Like
  • Comes with cover and weights

  • Attractive enough to sit on counter

  • Deep moat

What We Don't Like
  • Capacity may be too large for most

  • Ceramic weights more difficult to clean than glass

This fermentation crock comes with a burp lid which allows gasses to escape. The weights keep vegetables submerged beneath the brine during the process, and the moat also helps seal in odors. But because crocks should be packed about 75 percent full, this crock is best for making large batches of foods like German sauerkraut for parties or big families.

This compact, 2-liter (0.5-gallon) crock is pleasantly affordable and great for those just venturing into the world of home fermentation—or for making small batches of sauces like fermented hot sauce. It has a traditional water-lock lid that sits in a deep groove to hold water for the seal. It can hold about two pounds of vegetables, has a lead-free glaze, and comes with a pair of weights. It requires hand washing and is less attractive-looking than some of the other options, but is perfect for beginners.

What Our Experts Say

"I like crocks that hold 2 to 5 liters, letting me make small batches in various flavors and larger batches of favorite recipes. It's worth investing in crocks with water-lock rims and in weights that fit snugly; I get far less yeast buildup and far crisper pickles than with open ferments." Julie Laing, Canning and Fermenting Expert, Author of "The Complete Guide to Pickling"

Best for Kimchi

What We Like
  • Traditional brown glaze

  • More porous for best results with kimchi

  • Can ferment other foods

What We Don't Like
  • Unglazed interior difficult to clean

  • Slow shipping

While you can use any fermentation crock to make kimchi, traditionally it’s made in handcrafted earthenware pots called onggi with a dark-brown glaze fired at extremely high temperatures. Earthenware ceramics (made from fired clay) are more porous than stoneware or porcelain, so allegedly an onggi allows foods to “breathe” properly while fermenting for the best results. These clay pots are available in a variety of sizes and are used not just for making kimchi, but also fermented bean and chili pastes, soy sauce, and rice wine.

Types of Fermentation Crocks

Open Crocks

Open crocks are simple, straight-walled vessels sold with or without a lid and weights. In the most basic setup, an open crock can simply be covered with a cloth, with ordinary items like plates or stones used as weights, or you can purchase weights and a lid separately. Open crocks are generally less expensive, more readily available, easier to clean, and can fit large items through the wide opening, such as a whole head of cabbage. The drawbacks to an open crock are that they require close and regular attention to prevent mold infestations and brine overflow, and they can let strong odors escape.

Water-Seal Crocks

German-style water-seal crocks come with a lid that’s designed to sit in a shallow “moat” around the mouth of the crock. The moat is filled with water to form an airtight seal, which creates an optimal anaerobic environment for fermentation while keeping out mold, yeast, insects, and dust, and sealing in funky fermentation smells. Water-seal crocks are more difficult to find and pricier, and the narrower mouth makes them harder to fit large ingredients into and trickier to clean. On the plus side, they’re more hygienic, failure-proof, and hands-off, and many experts swear that water-sealed crocks are the best way to get a deep, fully developed flavor in your fermented foods. You just need to occasionally check the water level in the moat and top it off, as necessary, to maintain the seal. Water-seal crocks usually come with two crescent-shaped weights in addition to the lid.

What to Look for When Buying a Fermentation Crock


Fermentation crocks come in many different sizes, ranging from a gallon up to over 10 gallons. Before buying one, decide what food or drink you want to ferment, the amount you want to do at a time, how often, for how many people, and where you will store it when not in use. You might decide to start with a smaller-sized crock if you are just learning how to ferment foods.


Fermentation crocks are manufactured in various types of materials, including ceramic, stoneware, porcelain, glass, and clay. What foods or drinks you want to ferment in the crock should factor into your decision on which one to purchase, and the weight of the crock might be an issue for you, too. 


If you have limited space in your kitchen, then storing a fermentation crock is a concern. Some crocks are stylish with beautiful hand-painted decorations or glass designs, so you might enjoy displaying one of those on the counter when not in use. (They also make great gifts for cooks who already have everything else!) A small crock can also hold cooking utensils or other dry items and can fit nicely on a counter. Before purchasing a large crock, make sure you have room for it in a cupboard or out in the open. 


What's the difference between using a fermentation crock and a glass jar? 

A ceramic crock is the more traditional fermentation method, and many home fermentation experts say that it is the best (or even only) way to get a deep, fully developed flavor. But another option is using a wide-mouthed glass jar, such as a Mason jar, which has the advantages of being easier to find, inexpensive, and easy to clean since it doesn’t absorb odors or stains. The transparent glass lets you monitor progress, but they could be considered less attractive than an opaque crock, and the UV light they let in could negatively affect your fermented foods. They also generally hold smaller batches (perfect for foods like lacto-fermented carrots) and allow more air in and out than a water-sealed crock. A jar with a traditional lid can’t be tightened completely and needs occasional “burping” to allow built-up pressure to escape. These days many airlock fermentation lids are available for glass jars; they feature one-way valves that allow gas to escape but prevent air, mold, dust, and yeast from entering and keep strong odors sealed inside. On the downside, these extra lids take up more storage space in your kitchen and are an added expense. In the end, whether you use a crock or a jar comes down to personal choice, as each has its advantages and drawbacks. 

What size crock do I need?

For a small household of one or two people or those just starting out, a half-gallon (2-liter) crock should be sufficient; they are relatively light and won’t take up much counter space. For two to four people or larger batches, a 1-to-3-gallon crock might be more suitable and is still not overwhelmingly large or heavy. For larger households or those who have caught "fermentation fever" and plan to make multiple batches at a time, bigger crocks are available in sizes ranging from 3 gallons all the way up to more than 10 gallons. However, they start to get quite costly (and heavy) as the size increases. 

Are containers in any type of material safe to use for fermenting?

When looking for a crock that will be used for fermenting food or drinks, it’s important to make sure that it’s made with food-safe materials. Ceramic, porcelain, and glass are all nonreactive and will not corrode or leach chemicals into food, unlike some plastics and metals, but it’s important to make sure that any ceramics or porcelains you use with food have been made with a lead-free glaze.
