What is the science behind French press?

The French press, also called the cafetiere or coffee press, is a cylinder-shaped beaker (usually glass, but often plastic or steel) with a plunger. The piston of the plunger is made of mesh, allowing liquid to flow through it but not the larger coffee grounds.

How does a French coffee press work?

A French press makes coffee by immersing ground coffee in hot water and then separating the grounds from the coffee by pressing down the filter. Any hotter (water boils at 212ºF), your coffee will taste burnt. Any cooler, your coffee will be under-extracted, tasting flavorless and watered-down.

Why is French press coffee so strong?

French press coffee is also typically stronger than regular coffee because it is filtered with a fine mesh screen which allows the fines in the coffee grind to make it into the final brewed carafe.

Why is it so hard to press down the French press?

By far the most common reason the plunger on a French press is hard to push down is because the used grounds are too fine. This will plug the holes in the filter medium in such a way that it also blocks the liquid from getting through. Using a medium coarse grind is best to prevent this.

Why is French Press bad for you?

What is the chemistry of coffee?

The main constituents of coffee are caffeine, tannin, fixed oil, carbohydrates, and proteins. It contains 2–3\% caffeine, 3–5\% tannins, 13\% proteins, and 10–15\% fixed oils. In the seeds, caffeine is present as a salt of chlorogenic acid (CGA). Also it contains oil and wax [2].

Is French press coffee better than drip?

Is French press coffee stronger than drip coffee? No. The flavors in press coffee tend to be more intense because the stainless steel mesh doesn’t filter out the fine particles (called “fines”) or the natural oils. Drip coffee filters out both oils and fines, which give a cleaner taste that can seem milder.

Why does French press explode?

It happens if you use coffee that’s ground too finely, and doesn’t have to do with boiling. What happens is that the fine coffee grains block all the holes in the mesh. This means that the water is under more pressure than usual, since it can no longer pass through the plunger.
