It's found in almost every home, whether it's destined to dress salads or clean surfaces and kill fruit flies. But, effective as it is at those tasks, most of us struggle to get excited about vinegar. Today, however, a handful of enthusiasts and entrepreneurs are trying to launch a vinegar renaissance—one in which we appreciate vinegar (nearly) as much as the alcohol from which it's made. This episode, we visit vinegar attics in Italy, conduct an epic tasting in a backyard vinegar shed in west London, and chat with our in-house microbiologist, Ben Wolfe of Tufts University, in order to explore vinegar's long, frequently accidental history, its rumored health benefits, and its culinary potential. Plus: is the balsamic vinegar on your shelf the real thing? Listen now for all this and more!
The clue to vinegar's origins lies in its name: vin aigre, or sour wine in French. Michael Harlan Turkell, author of a new cookbook, Acid Trip, dedicated to vinegar's overlooked charms, told us that the first vinegars were likely made by accident in ancient Mesopotamia, along the banks of the Euphrates, when acetic bacteria in the environment fell into a cask of wine and soured it. Undeterred, people drank the vinegar anyway, before eventually discovering its multitude of other uses: as a health tonic (first recorded in ancient Greece), preservative (in ancient Egypt), and, finally, as a dipping sauce (in ancient China).

Until the late 1700s, vinegar was made in much the same way, all around the world, from all sorts of different fruits and grains, from pineapple to pomegranate—anything that contained enough sugar to be fermented into alcohol. It was a slow business: the microbes that transform alcohol into vinegar work at their own pace. Andy Harris, a food writer turned vinegar maker, told us that his single-varietal red wine vinegar can take between three and six months to sour, while Emilio Biancardi, whose family has been making vinegar for at least six generations at their estate just outside the Italian city of Modena, explained that it takes at least twelve years to produce the thick, sweet deliciousness that is traditional balsamic vinegar. Nowadays, however, Biancardi and Harris's approaches are the exceptions: after Louis Pasteur explained the microbial processes at the heart of vinegar-making, a handful of European scientists designed devices to speed things up, turning industrial ethanol into white vinegar in a matter of hours.

Today, celebrities from Katy Perry to Ranulph Fiennes claim that a daily dose of vinegar cures almost everything: arthritis, eczema, diabetes, even dandruff. With the help of our favorite microbiologist, Ben Wolfe of Tufts University, we look at the science behind vinegar's undisputed antimicrobial properties and its less well-documented super powers, as well as the secret to its varied flavors. And, for those bold enough to embrace the sourness, we explore the heady world of infused and barrel-aged vinegars, from the deep purple of Michael Harlan Turkell's favorite purple yam vinegar, to the banana notes of Andy Harris's Riesling vinegar, all the way to the king of vinegars itself: genuine, aged traditional balsamic vinegar of Modena. Enjoy!
Andy Harris's Vinegar Shed
Andy Harris sells his own London vinegar, aged in his back garden vinegar shed, on his website, alongside all the paraphernalia you need to make your own vinegar, as well as some of his favorite vinegars from other makers. He's also shared a handful of recipes to inspire you to start using vinegar more creatively, in stews, soups, and sauces.
Michael Harlan Turkell's Acid Trip
Michael Harlan Turkell's new book is called Acid Trip: Travels in the World of Vinegar, with Recipes from the Leading Chefs, Insights from Top Producers, and Step-by-Step Instructions on How to Make Your Own. His favorite vinegar (if forced to choose) is this Benimosu purple sweet potato vinegar.

Long-time Gastropod listeners will know and love our go-to microbiologist, Ben Wolfe of Tufts University: his research into microbial ecosystems in cheese and kombucha have made him the star of a couple of previous episodes.
Emilio Biancardi's Antica Acetaia Villa Bianca
Our morning in the Biancardi family's vineyards, vinegar attic, and dining table was among the most delicious and delightful of our travels. You can buy their superb traditional balsamic vinegar of Modena (D.O.P.) online here—and, if you're ever in the region, you should visit yourself!

Cristina Sereni and the Museo del Balsamico Tradizionale
Cristina Sereni is a balsamic vinegar maker and a former master taster, and she works at the fascinating Museum of Traditional Balsamic Vinegar in Spilamberto—which is also the headquarters of the consortium that governs and protects the D.O.P. traditional balsamic vinegar of Modena.
