How To Choose the Best Fermentation Crock for Perfect Sauerkraut, Pickles, and More

Fermenting and pickling at home can be a tricky process without the right tools. Fortunately, technology and innovation have nothing on the traditional tool known as the fermentation crock. These sturdy crocks have been used for centuries and haven’t changed much over the years. However, they are still a bit different than most kitchen tools and many of us aren’t familiar with what they are and how they work. We’ve created the guide below to help you learn everything you need to know about these crocks.

We’ll also discuss the features that matter most when you are buying one of these crocks. From water-sealed vs. open fermenting to the various reasons you’ll be using the crock, there are a lot of things to consider. Read on to get started making your list of factors for buying the best fermentation crock for your needs.

Water-Sealed vs. Open Crocks

There are two main methods of fermenting that are used today. Water sealing is the most common and has been used for canning and jarring foods for centuries. Open crocks are available, although they also have their own applications to consider. Let's start by looking at the uses for water-sealed crocks.

Water-sealed crocks are among the best choice for fermenting foods. These crocks are also referred to as Harsch crocks and consist of a lid and weights that help the fermenting process by sealing out the outside air and compressing the food. There is a water well at the top of the crock, which is designed to ensure that no air gets into the fermenting crock while it is doing its job.

This allows carbon dioxide to form and bubble out, preventing spoilage, and helping produce better results with fermentation. These crocks are ideal for those who want to produce large batches, as well as for those who simply want to prevent mold and yeast from forming inside the crock. In fact, some crocks that don’t use water sealing are notorious for creating mold and yeast and ruining perfectly good foods as a result.

Open crocks also have their place, but they are a much older design, and they don’t have as much predictability. These fermenting crocks are the ones that have been used for generations and usually require the use of a cloth or other object to be placed on the top opening during the fermenting process. These crocks are ideal for whole vegetables, liquids like kombucha, and some even come with weights to help create the barrier.

Typically, you will have an easier time using a water-sealed crock for fermenting. However, open crocks are an option for those who like the traditional style or who want a tool that can ferment whole vegetables at one time.

How Will You Be Using the Crock?

Of course, the primary uses of these crocks are fermenting and pickling. That's not what we mean when we ask how you’ll be using the crock, though. That part is obvious. What you need to consider here is what type of batches and foods you will be making. After all, if you’re only ever going to make small quantities of things, you probably won’t need a large crock.

On the other hand, if you plan on doing a lot of fermenting or you want to make larger batches, you’ll want to purchase a crock that has a larger batch capacity, such as a 3-gallon container instead of most of the crocks that come in at around 1.3 gallons. Keep in mind it’s not just about how much food you want to make, either. There has to be room in the crock for the weights and to allow the foods to expand, as they release gases during the fermenting process.

If you choose a fermenting crock that just barely fits the items that you want to put inside, you won’t have room for the weights or to allow the process to complete as it should. Always make sure that you think about how much food you intend to make or what types of pickling and fermenting you have in mind so that you can choose the crock that is the right size for the job.

The good news is that a single crock can often handle a lot of different jobs. If you want to make both small and large batches, you might want to purchase one in each size so that you aren’t wasting time with the big crock when you want to make a small batch of something. Think about not only the size of the crock but how many foods you can use it for when choosing the right model.

Does it Need to Be Portable?

Most people will set things up so that they don’t have to move their crock any more than necessary. However, there are some cases where you will want to relocate the crock or even just carry it from one place to another. Buying the largest crock available means that you probably intend to do a lot of fermenting, but without moving the crock around a lot.

For those who plan to move the crock or who need something easy to carry, size and weight will play a role in your decision. Besides being big enough to handle all the fermenting that you want to do, most of the crocks on this list include handles for easy carrying. This isn’t required, of course, but it’s definitely something to consider. These ceramic crocks aren’t overly heavy, but when they are filled with fermenting foods, they can get quite weighty.

How Fermentation Crocks Work

The basic premise of a fermentation crock is fairly simple to understand. These pots are designed, in some capacity, to cut off the oxygen supply to the food or liquids, allowing them to break down the lactic acid bacteria in the food that helps ferment or pickle whatever is inside. The vegetables will be cut or shredded, vinegar or saltwater will be added to the crock, and then the weights and/or lid are placed on top of the fermenting foods to secure them and remove excess oxygen and carbon dioxide throughout the process.

A fermentation crock is designed to work in a matter of 3-5 weeks for the most part, although they can be used for foods and drinks that take more or less time. Once the time has passed, the process will be completed. It was discussed above how the crocks work based on their style, but be sure to follow all fermenting instructions and manufacturer recommendations when using your crock for the best results. Typically, you will want to check on your fermenting and pickling at least a few times throughout the process to ensure that everything is going as it should.

There are ways to ferment foods without these crocks, but it typically won’t be as easy or as effective. That's why these crocks were created, after all. The entire goal is to make the process of pickling and fermenting easier. Whether you use the age-old open crocks like your grandparents did or you choose a lidded, water-sealed crock that offers better fermenting power for your favorite foods, you’ll be sure to enjoy the process when you have the right tools at hand.


The process of fermenting can be a lot easier and more enjoyable when you have the right tools for the job. Remember to choose a model that ferments in the way that you like, and to look for one that includes weights, the lid, and other necessary elements to make sure that you get everything that you need. If you want the best fermentation crock, look for products made in the U.S. or Europe to ensure the highest quality standards, and always choose a size that will give you more space than you need to allow the fermenting process to work as it should.
