occurs when water finds a "path of least resistance" through the coffee bed. Instead of flowing uniformly through all the grounds, the water rushes through a few preferential channels. This leads to uneven extraction : grounds along the channel are over-extracted (bitter, harsh), while grounds elsewhere are under-extracted (sour, weak). This is often the hidden culprit behind inconsistent or unpleasant-tasting coffee.

Applying the laws of physics to your daily brew requires balancing your inputs to optimize extraction yield (typically 18% to 22% of the coffee bean mass dissolved into the water). The Degassing Phase (The Bloom) When hot water hits fresh coffee grounds, trapped CO2cap C cap O sub 2 occurs when water finds a "path of least
Taste is the final measurement. Use physics to get into the Gold Cup range (18–22% extraction, 1.3–1.55% TDS). From there, adjust by taste, not dogma. This is often the hidden culprit behind inconsistent
