Book excerpt: Apple cider vinegar has a long history as a folk remedy for a variety of health conditions and, as a result, has achieved something akin to cult status among natural health enthusiasts. But many people don’t realize that there is a whole world of options beyond store-bought ACV or distilled white vinegar. In fact, vinegar can be made from anything with fermentable sugar, whether leftover juicing pulp or brown bananas, wildflowers or beer. With her in-depth guide, Kirsten K. Shockey takes readers on a deep dive into the wide-ranging possibilities alive in this ancient condiment, health tonic, and global kitchen staple. In-depth coverage of the science of vinegar and the basics of equipment, brewing, bottling, and aging gives readers the foundational skills and knowledge for fermenting their own vinegar. Then the real journey begins, as the book delves into the many methods and ingredients for making vinegars, from apple cider to red wine to rice to aged balsamic. Along the way, Shockey shares insights into vinegar-making traditions around the world and her own recipes for making vinegar tonics, infused vinegars, and oxymels.
