Last year, plenty of people took up the new hobby of baking sourdough. What better to do when you can’t leave the house? And, since sourdoughs are based on cultivating a microbial community of yeast and bacteria in what’s called a “starter,” these bakers had to learn how to care for the billions of microbes with which they now shared a kitchen. But as with many other hobbies, some of those new sourdough bakers probably gave up at some point. So what happened to their new microbe friends? What happens to a neglected sourdough starter? On this episode of the Scienceline podcast, we find out. Photo: A healthy sourdough starter can smell floral, yeasty or even like alcohol sometimes — but not rotten.
