What caused my homemade sauerkraut to turn pink?
Pink color in sauerkraut is caused by the growth of certain types of yeast on the surface of the kraut. These may grow if there is too much salt, an uneven distribution of salt, or if the kraut is improperly covered or weighted during fermentation. Discard pink sauerkraut.
