Which of these is fermented by yeast rather than by bacteria?

  • A.Sauerkraut made from salted shredded cabbage
  • B.Yoghurt made from milk by a starter culture
  • C.Brined cucumber pickles fermented in a tank
  • D.Beer

Answer: D

Beer is a yeast fermentation producing ethanol, whereas sauerkraut, yoghurt and pickles are all lactic acid bacterial fermentations producing acid. The distinction between yeast and bacterial fermentations runs through the whole of food microbiology.
