Crazy Korean Cooking Premium Kimchi and Sauerkraut Fermentation and Storage Container with Inner Vacuum Lid, 0.4 Gal (1.7L) Review (2026)

What it is

This is a small kimchi and sauerkraut storage container from Crazy Korean Cooking, sized at 0.4 gallons, or about 1.7 liters. The design borrows from the traditional Korean onggi clay pot, and the maker builds the container from polypropylene plastic blended with roughly 7 to 10 percent natural clay to add porosity similar to traditional earthenware. The container uses a double-lid system: an outer lid for a solid seal and an adjustable inner vacuum lid that presses down onto the food itself, reducing the air trapped between the lid and the kimchi's surface as it is eaten down.

Fit for the job

The 1.7 liter size positions this squarely as a small daily-use or fridge-door container rather than a fermentation vessel for a full head of napa cabbage, which typically produces several liters of finished kimchi. It works well as the container you portion a larger batch into once it is fermented, keeping the inner vacuum lid pressed down against the remaining kimchi as you serve from it over days or weeks, which slows oxidation and helps prevent the top layer from drying out or discoloring. For actually fermenting a full cabbage, a larger size in the same product line would be a better fit.

Build and materials

The polypropylene-and-clay blend is BPA, DEHP, and lead free according to the maker, and the container is stated as dishwasher safe and resistant to both heat and cold, with the container body safe in the microwave once the lids are removed. The double lid setup does more than most single-lid containers to contain kimchi odor in a shared fridge, which is one of the more common household complaints about storing fermented Korean vegetables. Being plastic rather than glass or ceramic, it is lighter and less likely to chip, though plastic can pick up some kimchi color and smell with heavy long-term use.

Value

For its size, the main value is in the double-lid design rather than raw capacity, since a basic container of similar volume without a vacuum lid would cost less but let kimchi degrade faster once opened. Buying it as a paired-down serving container alongside a larger fermenting vessel gives you both a proper ferment volume and a fridge-friendly portion size without overpaying for a single oversized container that takes up a full shelf. On its own as someone's only kimchi container, the small size limits how much you can make and store at once, which may mean more frequent batches. The durable, dishwasher-safe plastic body also means it should hold up to years of regular use without cracking the way some thinner containers eventually do.

Who should buy it

This suits singles, couples, or anyone who eats kimchi steadily but in small amounts and wants a fridge-door-sized container that slows spoilage once opened. It also works well as a secondary container to portion out a larger ferment for daily use, keeping the bulk of a batch sealed elsewhere. It is not the right pick for anyone planning to ferment a whole cabbage or a large batch of sauerkraut in one vessel, where the 1.7 liter capacity would be used up quickly. Buyers who share a fridge with people sensitive to kimchi's smell will also value the double-lid design more than someone with a fridge to themselves.
