Grinding points based on extraction method

NOTES ON THE COFFEE GRINDING POINT:

The Grind Point is not an exact science. There are a series of recommendations depending on the type of extraction, but the last word is always with the consumer.

Coffee making is always based on the same principle: run hot water through a roasted coffee bean to extract its properties. The speed (or force) with which the water circulates is called pressure. The higher the speed, the higher the pressure.

The grind point will determine the surface area of ​​the coffee bean that is exposed to water. In a fine grind, there is much more grain surface area than there is in a coarse grind point.

The greater the exposure (that is, the finer the coffee), the greater the proportion of the basic coffee oils, which give body and bitterness to the final cup. The thicker, the higher its acidity and the less hidden the nuances of flavor will be.

In general, the more pressure and speed of elaboration, the finer the point of grinding. An espresso machine will take 20 seconds to make a coffee, so if it's not fine, it won't taste like anything. On the other hand, coffees that are extracted by decanting water will need more time and the grind will be coarser.

Émbolo (o prensa francesa). Cafés Caracas.

Plunger (or french press)

One of the simple coffee making tools in the world.

Most important of all, make sure that after pressing, you decant the coffee. If you don't, you will leave the prep exposed to the particles and they will continue to be extracted. Since the bitter compounds are the last to be extracted, you can end up with a bad taste in your cup of coffee.

A coarse grind is normally recommended.

Perfect type of coffee grind for a Kalita Wave coffee maker

How is the coffee filtering process? With the Kalita Wave it is a pour/drip method, like the V60, but it has its differences. First of all, it has a flat bottom with three small holes in it. This affects the flow of water, allowing it to collect at the bottom before dripping. In turn, this makes for a more consistent cup of coffee.

What type of coffee grind is needed? For the Kalita Wave coffee maker, it is recommended to prepare it as if it were a V60, including the medium-fine grind.
