When brewing coffee according to the full immersion method, the coffee grounds are completely mixed with the water before being separated by a sieve filter in the next step after a certain brewing time.
The immersion method gives the coffee a very full-bodied taste, as the metal sieve does not filter out the fats and oils contained in the coffee during preparation, unlike a paper filter. The grind is rather coarse and should resemble the consistency of cane sugar.
Well-known examples of this principle are the French Press and the Aeropress.
