How filter paper properties—thickness, porosity, material, and treatments—affect flow, clarity, and flavor in brewed coffee.
How fines migration—the movement of tiny coffee particles during extraction—affects flow restriction, channeling, and cup quality.
Why whole beans stay fresher longer than ground coffee, and how particle size impacts oxidation, aroma loss, and shelf life.
Why microbial growth is a concern in cold coffee, how to minimize risks, and best practices for safe storage and shelf life management.
How temperature stability during immersion and hybrid brewing affects extraction consistency and flavor clarity.
