A brewing apparatus (1,101) for making infusions, particularly espresso, including 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, the lower container (11,111) and top cover (12,112) being 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 the velocity is increased to increase pressure in the chamber; the first velocity being lower than the 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. |
