Filter permeability and resistance
How the physical properties of coffee filters affect water flow, extraction, and cup quality.
Extraction yield
Grind size effects on flow
How grind particle size influences water flow, extraction efficiency, and flavor balance in brewed coffee.
Bypass and dilution strategies
How manipulating water flow and concentration after extraction affects cup strength, flavor balance, and consistency.
Contact time and temperature
How brewing time and water temperature influence extraction, flavor balance, and beverage quality.
Brew ratio and dose/yield math
How to calculate and adjust brew ratios, dose, and yield to achieve consistent extraction and desired cup strength.
Extraction yield and beverage strength
How the amount of coffee extracted relates to the final beverage strength and flavor.
