Abstract:
A wine pouring spout that aerates the wine pouring therethrough comprises a generally tubular construction with a flow path extending along the axis of the spout. The flow path is provided with a Venturi constriction, and a Venturi intake port delivers ambient air to the low pressure zone of the constriction, as is generally known in the prior art. A closure member is pivotally joined to the spout, with a distal end that rotates to seal the spout outlet, and rotates open as the spout is tipped to a pouring position. A filter is removably secured in the proximal end of the bore in the spout to remove sediment from the wine.
