What is body in coffee? Mouthfeel, filters and grind

What creates body in coffee?

Oils and suspended solids create most of it. Perfect Daily Grind explains that brewing produces both soluble and insoluble compounds. The insolubles, solids and oils that stay suspended in the liquid, add body, especially the oils.

Roasting adds to it. Perfect Daily Grind says melanoidins, formed in the Maillard reaction, contribute to body. It quotes Sweet Maria's linking a more syrupy mouthfeel to carbohydrates released when first crack is stretched out.

The SCAA cupping protocol judges body by the "tactile feeling of the liquid in the mouth," especially between tongue and palate. It credits heavy body to "brew colloids."

Is body the same as mouthfeel?

Mostly, though some tasters split them. Coffee Review treats the two terms as the same thing. Perfect Daily Grind quotes Scott Rao defining body as "a beverage's weight or fullness perceived in the mouth."

Maxwell Colonna-Dashwood, also quoted there, separates weight from texture. You could have "a light body with a sticky mouth feel," he says, or a big body with a juicy one. In everyday use, body and mouthfeel mean the same thing.

Why does French press have more body than pour-over?

Because the filter lets more through. Perfect Daily Grind says French press is known for high body because its metal filter lets oils pass. Paper pour-overs trap oils and lean toward clarity instead.

Perfect Daily Grind says espresso has greater body because of its much higher brew ratio, and that its crema is filled with oils and melanoidins. For the two immersion methods side by side, see AeroPress vs French press.

Which coffees have more body?

Origin and processing matter. Coffee Review names Sumatra and Costa Rica as heavier-bodied, and Kenya as medium. The SCAA protocol uses Sumatra as a high-body example and Mexico as a low-body one.

Perfect Daily Grind says natural-processed coffees have "bigger, rounder body" than washed ones. Honey and pulped natural processes add body too: the more mucilage left on the cherry, "the more body you'll get in the cup."

Does your grinder change body?

It can, through the fines it makes. Honest Coffee Guide says conical burrs generally produce more fines, creating "drinks with more body and texture." Flat burrs generally produce fewer, which "will reduce body and increase clarity."

This is a tendency, not a rule. Burr design and alignment vary within each type, and the effect of fines on taste is debated. The conical burrs and flat burrs pages cover the evidence on both sides.

If you prefer a fuller cup, this is one reason to look at conical grinders. Fellow Ode Gen 2 vs Fellow Opus shows a flat and a conical grinder from the same maker.

How can you brew for more or less body?

Change the filter, the strength or the grind. Perfect Daily Grind says how much oil your method and filter allow through affects body. It adds that you can adjust brew ratio and strength in manual methods for more or less body.

A metal filter or French press gives more. A thick paper filter gives less. For ratio adjustments, the brew calculator lets you test a stronger or weaker recipe.
