11 of 51 jurisdictions (50 states plus DC) allow sauerkraut and kimchi to be made in a home kitchen under cottage food rules, often with conditions, and 3 more allow it with a special home license or program. 18 require a commercial kitchen. Here's why, and where each state lands.
Sauerkraut and kimchi are preserved by lactic acid fermentation. Bacteria naturally present on the cabbage convert sugars into lactic acid, which lowers the pH over several days. Because the acid is produced by fermentation rather than added, these foods are treated differently from acidified foods, and state rules vary widely.
