Abstract: A fluid aerator (1) comprising a fluid vessel (2) and a pipe (4) extending from the interior of the fluid vessel (2) to the exterior. The pipe (4) has inlet means for permitting liquid to flow into the pipe (4) from the vessel (2) and is closed at its lowermost end but has one or more outlet holes (8) arranged in the wall of the pipe where the fluid exists from the pipe (4). The pipe (4) is movable relative to the vessel (2) between a first position in which the outlet holes (8) are distant from the vessel and a second position in which the outlet holes (8) are closer to the vessel. By means of the movable fluid supply pipe (4) the same fluid aerator can be used both in relation to delivering aerated fluid into a large bottle and to delivering smaller amounts of aerated fluid to a smaller container, such as a wine glass.
