Claim:
An apparatus for mixing two fluids, the apparatus comprising: a. a conduit through which a first fluid flows, the conduit having an air ventilation port and a constricted intermediate region; b. a plurality of lateral tubes for introducing a second fluid substantially at the constricted intermediate region, at least two of the lateral tubes being formed at acute angles relative to the direction of flow of the first fluid through the constricted intermediate region and with respect to central, vertical and lateral axes thereof; and c. an air ventilation tube, having first and second ends, the first end fluidly coupled to the air ventilation port for introducing air into a bottle and for preventing leakage from the lateral tubes during use, wherein the ventilation tube includes a ventilation tube cavity, for capturing backwash of the first fluid as pouring is terminated, wherein the diameter of the ventilation tube cavity is greater than the diameter of either the air ventilation port or the second end of the ventilation tube.
