Doran and Chris also host a podcast called Coffee Literature Review, where they invite a guest from the coffee industry and discuss a scientific paper connected to coffee somehow: https://podcasts.apple.com/us/podcast/coffee-literature-revi...

At the SCA Expo a few years ago, they were doing electrochemistry on brewed coffee to measure caffeine content, and also change the flavor in weird ways. This latest paper seems to build on previous experiments in a similar vein: https://sca.coffee/sca-news/25/issue-18/amped-up-using-elect...
