Brewing

French press can taste rich without sludge or bitterness when grind, time, agitation, and pouring are controlled.

Understand how hardness, alkalinity, filtration, and kettle habits affect extraction and flavor at home.

Separate weak strength from poor extraction and fix thin coffee through dose, grind, contact time, and water choices.

Identify harshness from over-extraction, fines, roast, water, temperature, and dirty equipment without guessing wildly.

Use grind size ranges for espresso, pour-over, immersion, moka pot, and cold brew as adjustable starting points.
