<p>A brewing apparatus (1,101) for making infusions, particularly espresso, of the type comprising a pumping unit (2,102) for pumping water from a tank (3,103) to a water superheating boiler (6,106), wherein the boiler (6,106) has a lower container (11,111) closed at its top by a perforated cover (12,112) allowing superheated water to flow into the lower container under pressure, said lower container (11,111) and top cover (12,112) being formed of a plastic material. The brewing process includes a first step in which water is fed and pumped at a first feed velocity, a second step in which said velocity is increased to increase pressure in the chamber; said first velocity being lower than said second velocity. The upper boiler body (112) has the closing face (112a) of such a shape as to receive a corresponding single-dose pod (100) packed in paper, aluminum or another biodegradable material containing coffee or another flavor base in general.</p> |
