Yes, I know you are correct. I choose the word "spoiled" as a shorthand for the fermentation process. It is "spoiled" in the same sense that yoghurt and cheese are "spoiled" milk. Not entirely accurate, but perhaps more descriptive to those who don't know what it is. In retrospect, I should have used "fermented" rather than "spoiled."
