Percolation vs immersion dynamics
Understanding how water flow dynamics—percolation vs immersion—affect coffee extraction and flavor development.
Grind size
Extraction yield and beverage strength
How the amount of coffee extracted relates to the final beverage strength and flavor.
Maintenance and cleanliness
How proper maintenance and cleanliness of grinders preserve performance, consistency, and coffee quality.
Static, clumping, and RDT
How static and clumping affect grind consistency and how the Ross Droplet Technique (RDT) can mitigate these issues.
Alignment and parallelism
How precise alignment and parallel positioning of burrs affects grind consistency and extraction performance.
Third Wave movement and specialty coffee
In this topic we explore the rise of the Third Wave coffee movement, how it redefined coffee as an artisanal product, and the role of specialty coffee in reshaping global consumption, trade, and culture.
