May 2025 Friday’s e-links: Using Physics to Make Coffee

Every once in a while, (and sometimes each day) I listen to a great podcast, enjoy an article, or see a good video that I want to share with you. These are my e-links.

Like me, maybe you really care about your coffee. I mail order my beans, grind them before each cup, and use a pour over Chemex. So, this week’s e-link focuses on the science of making the best pour over. In a NY Times article, a University of Pennsylvania physics professor realized that basic physics principles explained how to generate the best coffee flavor. It relates to the speed of the water and height of your kettle. It takes us to a liquid’s absorption rate and fluid dynamics. But do take a look. Even if don’t like coffee, the ideas are more universal. Also, they are fun to read about.

I should add that I’ve done what he suggests. And yes, it works.
