Extraction

Also known as extraction · extracción de solubles · brewing extraction

Diagrama de extracción

What it is and what sets it apart: Extraction is the overall process; EY% quantifies it; TDS is beverage strength. Not the same as ratio.

How it’s used or measured: Control via grind, contact time, temperature, agitation, ratio, distribution. Measure with refractometer + tasting; place on the brew chart.

Flavours and cup impact: Balanced: sweetness and pleasant acidity. Under: sharp/green; over: bitter/dry.

Technical notes: Variables interact—finer grind raises extraction if flow allows.

Common mistakes: Saying “more extraction” by blindly raising water. Equating high TDS with good extraction.
