For years, I used cold brew as a last resort—the only brew method to tame dark, oily beans that were too bitter for hot water.
Then one day, I took a chance on a Guatemalan Gesha and brewed it cold. The result? A massive explosion of florals I’d never tasted before. That single cup sent opened my eyes into how extraordinary cold brew can be.
In this episode, I speak with world-leading coffee scientists who explain why brewing with cold water tastes so different from chilled hot coffee.
You’ll learn how certain flavors leap into your cup (and how others mysteriously vanish) when you lower the brew temperature.
You’ll also discover there are hidden “cold brew gems” in beans you thought you knew. So before you grab the kettle, consider this: sometimes all you need is cold water.
