The hole size is such that it holds a portion of coffee contained in the extraction chamber, at the constant pressure of hot water flow, so that the extracted drink of espresso coffee passes via the hole with foam. The espresso coffee produced by the method contains foam, which has distribution of identical bubbles diameter within the range of 20-150 micron.
