Yeast's Impact on Whisky

WhiskyCast

Yeast is one of the three main ingredients in whisky, along with grain and water. While we understand what grain and water contribute to the taste of a whisky, yeast's contributions are far more mysterious. In fact, people were distilling whisky from fermented mash hundreds of years before scientists even figured out that yeast exists, let alone how it works. After our deep dive into the science of oak trees last month, we had requests to do something similar with yeast - and Indiana University biochemistry professor Matt Bochman joins us this week to help. His laboratory research involves studying yeast cells to unlock keys that may help us fight cancer and other diseases, but his informal research focuses on home brewing. He's also a consultant to brewers and distillers on fermentation issues, and shares his expertise with us on WhiskyCast In-Depth. In the news, Great Britain and the European Union are at odds over Brexit again. We'll also look at two new programs aimed at improving diversity in the whisky industry, and on Behind the Label, we'll have proof that not everything you may see about whisky on the Internet is true!
