An improved venturi apparatus for the incorporation of air into a liquid as it is poured from a bottle. The preferred' embodiment of the invention comprises an entry section, a constricted intermediate section, and an outflow section. Lateral tubes extend from the constricted intermediate section, so as to form an acute angle relative to both, the central and cross-sectional axes of the constricted intermediate section, thereby preventing leakage of liquid out through the lateral tubes during use and subsequent handling. The device includes a ventilation tube with a ventilation cavity for capturing backwash of the liquid as pouring is terminated, and for preventing leakage from the ventilation port. |
