Introduction
The first law of filter coffee physics is thermodynamic. Water acts as the solvent, and its temperature dictates the kinetics of extraction. Now, go find that and brew with scientific intent
The heat transfer during brewing can be described using the principles of convective heat transfer. The hot water loses heat to the surroundings as it flows through the coffee grounds and the filter, resulting in a decrease in temperature. The rate of heat transfer is influenced by the temperature difference between the water and the surroundings, as well as the flow rate of the water.
The (developed by Dr. Ernest Lockhart at MIT in the 1950s) remains the standard graphical solution linking TDS, EY, and strength.
