Venturi apparatus

A method of aerating wine, the method comprising:

• disposing a venturi apparatus higher than and in relation to a wine receptacle such that a fluid flow path provided by the apparatus is disposed to direct wine exiting from the venturi apparatus into the receptacle;
• pouring wine from a bottle, the wine flowing downward due to gravity, through an opening provided by the venturi apparatus exposed to the atmosphere into a wine-receiving portion of the fluid flow path, the wine being subject to atmospheric pressure in the wine-receiving portion;
• continuing to dispose the apparatus such that wine flows downward from the wine-receiving portion along the fluid flow path;
• producing a pressure differential between the fluid flow path and the atmosphere in a vicinity of an air intake of the apparatus;
• drawing air through the air intake due to the pressure differential;
• mixing the wine with the air drawn through the air intake to form aerated wine;
• and
• continuing to dispose the apparatus higher than and in relation to the receptacle such that the aerated wine flows from the apparatus into the receptacle.

An apparatus for facilitating the mixture of a liquid and a gas, the apparatus comprising:

• a fluid receiving section configured to be open to and in fluid communication with the atmosphere to receive the liquid due to the liquid being poured, the fluid receiving section defining a narrowing passageway;
• an intermediate passageway fluidly coupled to the fluid receiving section to receive the liquid from the fluid receiving section;
• an exit passageway fluidly coupled to the intermediate passageway, the intermediate passageway being located between the fluid receiving section and the exit passageway;
• and
• at least one side passageway fluidly coupled to the intermediate passageway and configured to allow the gas to be drawn into the intermediate passageway to mix with the liquid, wherein:
• the fluid receiving section, the intermediate passageway and the exit passageway are disposed to define a fluid flow path for the poured liquid, and
• the fluid flow path between the fluid receiving section and the exit passageway causes the liquid passing therethrough to experience a decreased pressure to draw the gas through the at least one side passageway when the liquid passes therethrough at the decreased pressure.
