Kimchi, the iconic Korean side dish, is a global culinary sensation. Its fiery, fermented flavor and numerous health benefits have made it a staple in kitchens worldwide. But what about the star ingredient, the very foundation upon which this culinary masterpiece is built? What is the name of the cabbage that makes kimchi, and why is it so special? Let’s delve deep into the world of “kimchi cabbage,” uncovering its botanical identity, historical significance, and unique characteristics that make it the perfect base for this beloved fermented food.
Decoding “Kimchi Cabbage”: More Than Just a Name
The cabbage used for making kimchi is specifically known as Baechu (배추) in Korean. This translates to “Chinese cabbage” in English, but it’s important to understand that not all Chinese cabbages are created equal. Baechu, the kimchi cabbage, is a specific variety within the broader Brassica rapa species, cultivated for its distinct texture, taste, and suitability for fermentation.
Brassica rapa: The Family Tree
To understand Baechu’s place in the botanical world, we need to explore its family tree. Brassica rapa is a plant species that encompasses a wide range of vegetables, including turnips, bok choy, napa cabbage, and various Asian greens. Baechu, or kimchi cabbage, is a cultivated variety specifically bred for kimchi making.
Distinguishing Features of Baechu
Baechu differs significantly from other cabbages, even other Chinese cabbages. Its leaves are more tender, its flavor is milder, and its water content is optimized for the fermentation process. The head of Baechu is typically elongated and oval-shaped, with tightly packed, pale green leaves that have ruffled edges. This unique structure allows for optimal absorption of the kimchi seasoning, creating that signature flavor explosion.
The Historical Journey of Baechu
The history of Baechu is intertwined with the history of kimchi itself. While kimchi-like preparations have existed in Korea for centuries, the use of Baechu as the primary ingredient is a more recent development, dating back to the late 19th and early 20th centuries.
Pre-Baechu Kimchi: A World of Radishes and Other Vegetables
Before Baechu became widely available, kimchi was primarily made with radishes, turnips, and other locally available vegetables. These early forms of kimchi were seasoned with garlic, ginger, and chili peppers, but the flavor profile was different from the Baechu kimchi we know today.
The Arrival of Baechu: A Culinary Revolution
The introduction of Baechu to Korea marked a turning point in kimchi making. Its unique characteristics, including its tenderness and ability to absorb flavors, made it the ideal cabbage for fermentation. Baechu kimchi quickly gained popularity, becoming the dominant type of kimchi in Korea.

Finding and Selecting the Perfect Baechu
Choosing the right Baechu is essential for making delicious kimchi or using it in other recipes. Here are some tips for finding and selecting the perfect Baechu:
Look for Firm, Tightly Packed Heads
The head of the Baechu should be firm and tightly packed, with no signs of wilting or bruising. A loose or soft head indicates that the cabbage is past its prime.
Check the Color of the Leaves
The leaves of the Baechu should be a pale green color. Avoid cabbages with yellow or brown leaves, as this indicates that they are not fresh.
Feel the Weight of the Cabbage
The Baechu should feel heavy for its size. This indicates that it is full of moisture and will have a good texture.
Consider the Size of the Cabbage
Choose a Baechu that is the right size for your needs. A large cabbage may be too much if you are only making a small batch of kimchi.
Preserving Baechu: Keeping it Fresh
Baechu can be stored in the refrigerator for several days. To keep it fresh, wrap it in plastic wrap or store it in a plastic bag. You can also blanch and freeze Baechu for longer storage.
