The finished acidity of good sauerkraut is usually about

  • A.One tenth of one per cent lactic acid at most
  • B.Five to six per cent acetic acid by weight
  • C.One and a half to two per cent lactic acid
  • D.Ten to twelve per cent lactic acid by weight

Answer: C

Around 1.5 to 2 per cent lactic acid, with a pH near 3.5, is enough to preserve the cabbage and give the characteristic sharpness. Ten per cent is far beyond what these organisms can reach, and the dominant acid is lactic rather than acetic.
