The grinding or grinding of coffee is the process, both domestic and industrial, of reducing the roasted bean to powder to facilitate the preparation of the infusion using a coffee mill or grinder.

 

With different types of coffee preparation, not all have the same type of grind, so here I have prepared a guide for when you buy your Chemex, V60, French Press, etc.

 

Know what type of grind you should buy or prepare if you have a mill at home. Pick up some ground coffee by pinching with your index finger and thumb and rubbing them gently.

 

The types of grind are:

 

• Coarse: when the grind is coarse, the coffee does not remain on the fingers and they remain clean once the test is carried out. It is the most used for coffee tastings or other preparation methods such as the French press, the metal filter or cold brew.

 

• Coarse Medium: Coarse salt texture ideal for a Chemex filter coffee maker.

 

• Medium: Coffee with a medium grind slightly stains the fingertips, but much of the coffee does not stick to them. It facilitates contact with the coffee, but without the need to shorten the extraction time. Brown sugar texture compatible with flat bottom filter drip methods such as Kalita Wave, automatic drip brewers and siphon brewers.

 

• Fine Medium: Texture slightly coarser than table salt, optimal for AeroPress and drip cones like V60 or Clever Coffee Dripper.

 

• Fine: if the coffee sticks easily to the fingertips and stains them, this is a coffee with a fine grind. It is used for the most common infusion methods, in which pressure is used, it allows the water to come into contact with as much coffee as possible and thus the extraction is carried out quickly, ideal for espresso from espress machines , the Italian mocha.

 

• Extra-fine grinding: it is a talc type grinding. It is normally used for Turkish type coffees, in which a granulate so fine that it almost dissolves is necessary.
