This video discusses the science behind making the perfect cup of coffee. It covers various aspects, including coffee bean types (Arabica and Robusta), temperature, water quality, grind size, and brewing methods (infusion, decoction, pressure). The video emphasizes that the ideal coffee is a matter of personal preference and that science can help improve the brewing process.
