A bottle aerator of the type having a venturi tube having a constricted section with a narrower cross-sectional section and a fluid inlet section having a wider cross-sectional section, such that the fluid pressure is lower in the constricted section compared to the pressure in the fluid inlet section, and the fluid speed is higher in the constricted section compared to the fluid speed in the fluid inlet section, which is improved by the constricted section being constructed and arranged so that when the bottle aerator is inserted into a bottle, the constricted section is positioned inside the bottle. The air inlet is provided at or below the constricted section, which allows air from outside the bottle to mix with the fluid as it passes through the constricted section, so that the fluid is aerated while still inside the bottle. |
