Fermentation crocks provide you with an effective traditional way of fermenting popular vegetables.

Most crocks are made of stoneware such as ceramic, which provides an ideal environment and surface for fermenting cabbages, and probiotic-rich foods such as sauerkraut, kimchi, pickles, and several others.

Water-sealed crocks, such as the ones we’ve compiled for you, are great because they provide optimal conditions for fermenting. They come in different capacities.

Check out our top fermentation crocks review to discover the ones that are best suited for preparing your favorite probiotic-rich foods.

What To Check Before Buying Fermentation Crock?

How to Buy the Best Fermenting Crock
Photo: Kenley

1. Water-Sealed Crocks vs. Open Crocks

When shopping for fermentation crocks, you will encounter them in 2 main types: water-sealed, and open crocks.

Water-sealed crocks come with channel or tough, on which you can pour water and then insert a lid to create the seal. Water seals are great for keeping oxygen and other contaminants away from the crock’s content.

Open crocks, as the name suggests, have no tough or lid. You will need to improvise on the cover to create the seal if needed.

2. Size and Capacity

Fermenting seals come in different sizes and capacities, which is measured in liters or gallons.

High-capacity crocks can hold 5 to 11 liters of content. Ohio Stoneware Crock Kit and Gardener’s Supply Company 2443 are such crock with 11-liter (3 gallons) capacities.

It’s worth noting that the higher the capacity of your crock, the more space it occupies.

Low-capacity crocks hold up to 2 liters of content and are great for those with space limitations.

3. Fermentation Crock Materials

Material is another key consideration to make when choosing to ferment croaks. Ceramic is the most common material used to make crocks, and all the ones on our list contain it.

Ceramic is strong, toxin-free, and can is known to preserve the rich tastes of the items placed in it.

Crocks can also have coatings made of different materials. The glaze is the most common material used. You should ensure, however, that your crock is free of toxic materials and chemicals such as lead and cadmium.

4. Lids and Handles

Your crock may come with or without a lid. Crocks with lid offer additional value because the lid combines well with a water seal to keep out oxygen from the fermentation process happening inside.

Lids also work well to keep contaminants such as dust and insects away from the contents of crocks.

Handles are great additions to crocks, especially those high-capacity ones that tend to get heavy when fully loaded with pickles, cabbages, and other vegetables.

You can use the handles, such as those on Kerazo COMINHKR099130 to lift the crock.

5. Construction and Safety

Because a crock is built as a stoneware pot, it can be heavy especially as capacity increases. The weight of the crock should be constantly watched to ensure your safety when using the pot.

If the pot is heavy, try to minimize how often you move it. Also use the handles for lifting, if they are available.

The ceramic construction of most crocks is strong and firm, especially that of the German-style, Kerazo COMINHKR099130, to ensure durability even with intensive fermentation.

6. Easy to Clean

We all appreciate stoneware and cookware that is easy to clean. Fermentation crocks try to simplify this process too.

Since most crocks are made of ceramic, that can be cleaned easily by simple handwashing and rinsing with water. Crocks with wide diameter openings are easier to handwash because you can insert your hand into them easily.

Others such as Gardener’s Supply Company 2443 simplify the cleaning process even further by being dishwasher safe.
