Q: If sauerkraut is fermented, does that mean pickles are fermented too?

A: Not necessarily – while all fermented foods are pickled, not all pickled foods are fermented. Most supermarket pickles on the shelf have been preserved in an acidic medium, like vinegar. While vinegar itself is a product of fermentation, it does not offer the probiotic value of fermented foods. Fermented pickles can be purchased, but they are not readily available and cost much more than a traditional pickle. For those of you who are ambitious, you can ferment your own pickles!
