Exploring Variability in Coffee Brewing Methods

The chapter analyzes a study on the variability of coffee brewing among baristas using different methods like V 60, AeroPress, French press, and a new device. It explores the impact of human versus machine brewing, variations in Total Dissolved Solids (TDS) due to grind size, and the significance of brew time uniformity. The discussion highlights the importance of understanding water chemistry, controlling parameters like water temperature and grind size, and the challenges of comparing coffee samples accurately.
