Coffee extraction is the process by which coffee solids and oils are extracted from the coffee beans. The extraction process is affected by a range of factors, including the particle size and distribution of the coffee grounds, the brewing time, and the water temperature.

The physics of filter coffee brewing is complex and involves a range of physical phenomena, including fluid dynamics, heat transfer, and coffee extraction. By understanding the physical processes involved, coffee brewers can optimize their brewing conditions to produce high-quality coffee. The optimal brewing conditions for filter coffee are a coffee-to-water ratio of 1:15 to 1:17, a brewing time of 3-4 minutes, a water temperature of 93-96°C, and a particle size and distribution of 0.8-1.2 mm.

The fluid dynamics of filter coffee brewing involve the flow of hot water through a bed of ground coffee beans. The water flows through the coffee due to gravity, and the flow rate is determined by the permeability of the coffee bed and the pressure drop across it. The permeability of the coffee bed is affected by the particle size and distribution of the coffee grounds, as well as the packing density of the bed.
