From the opening

Fermented pickles sour because lactic acid bacteria made acid in the jar from the vegetable's sugars. Vinegar pickles sour because acetic acid was added from outside, and a similar tang can hide two different routes. The opening covers lactic acid made in the jar, acetic acid poured in at packing, and what cloudiness means in a brine.
