Wine, bred, pickles, beer, vinegar, cider, are fermented food and drinks.More relevant to the discussion, I've found that MOST (not all though) Americans have a bit of a bias against fermented foods. Having a mom from Vietnam meant I grew up eating tons of fermented foods (soy sauce, fish sauce, kombu, and kimchi are all examples) so I can confidently say that there is a VAST difference between spoiled food and fermented food. If you've ever drank beer then guess what, you've also had fermented food.
Nowadays I live in Belgium, where we get old-school German fermented saurkraut and similar foodstuffs on the regular. So fermented foods are still a large part of my diet. Only reason I haven't eaten fermented foods in a while is because I'm pregnant, but I'll probably go back to that (and delicious farm-fresh raw milk) when he's born.
