"I had thought fermentation was controlled death. Left alone,..." — Michelle Zauner quote meaning

I had thought fermentation was controlled death. Left alone, a head of cabbage molds and decomposes. It becomes rotten, inedible. But when brined and stored, the course of its decay is altered. Sugars are broken down to produce lactic acid, which protects it from spoiling. Carbon dioxide is released and the brine acidifies. It ages. Its color and texture transmute. Its flavor becomes tarter, more pungent. It exists in time and transforms. So it is not quite controlled death, because it enjoys a new life altogether.
