Gastropod

Food with a side of science and history. Every other week, co-hosts Cynthia Graber and Nicola Twilley serve up a brand new episode exploring the hidden history and surprising science behind a different food- or farming-related topic, from aquaculture to ancient feasts, from cutlery to chile peppers, and from microbes to Malbec. We interview experts, visit labs, fields, and archaeological digs, and generally have lots of fun while discovering new ways to think about and understand the world through food.

The Bottle vs. Tap Battle Finale: Alkaline H2O, Lead Pipes, and, Yes, Water Sommeliers


As promised, it's time for the final splashdown in the battle of bottled vs. tap water. When we left off last episode, bottled water had staged a miraculous comeback thanks to Nike, yuppies, and Orson Welles. Today, it's America's favorite liquid refreshment: we buy more bottled water by volume than any other packaged beverage, even though you can get its less glamorous cousin, tap, delivered directly to your home for mere pennies. So, is bottled water somehow better than tap? Is it safer, or even just nicer tasting? This episode, we dive into the science behind the taste of water (spoiler: it has to do with spit) and explore the fine art of bottled water appreciation, before sharing the secret to making your own DIY Pellegrino. Meanwhile, we've all heard the water horror story unfolding in Flint, Michigan: should we be worried about lead or other chemicals in our tap water—or in the bottles on grocery store shelves? All that, plus our very own water taste test, as we declare the ultimate victor in this war of the waters.
