The tactile weight of coffee in your mouth — what makes one cup feel like skim milk and another feel like cream. Body is independent from flavor and from strength; you can have a strong, light-bodied cup and a weak, heavy-bodied one.
Body comes from suspended particles (microfines that escape the filter), soluble oils (lipids dissolved during brewing) and dissolved compounds that change viscosity. Espresso has the most body of any brewed coffee; French press has the most among non-espresso methods; paper-filtered pour-over has the least.
What controls body in pour-over
- Filter material. Paper strips fines and oils → light body. Metal lets both through → heavier body. Cloth sits in between.
- Grind size. Finer grinds shed more fines into the cup, increasing perceived body even through paper.
- Roast level. Darker roasts develop more soluble compounds and oils → fuller body. Lighter roasts lean light.
- Bypass. More bypass dilutes body even when extraction is otherwise the same.
How it tastes
Light-bodied cups read tea-like, juicy, articulate. Heavy-bodied cups read syrupy, coating, viscous. Neither is right or wrong; they're contextually different. A delicate Ethiopian shows best in a light-bodied paper-filter brew. A rich Brazilian or Sumatra is most itself in a French press where the oils carry through.
If you want to add body without losing clarity, brew slightly finer through paper and accept the trade.
