Bottle Attachable Decanting Aerator Apparatus

A bottle attachable decanting aerator apparatus comprising a spout member insertable into the mouth of an existing bottle, said spout member comprising:

• a pouring end;
• an engagement end;
• a top side;
• a bottom side;
• a removed section cutaway from the top side;
• a conical end piece disposed at the engagement end, said conical end piece having a truncated vertex sized fittable into the mouth of an existing bottle;
• a first arch disposed upon the spout member proximal the pouring end, said first arch disposed between the pouring end and the removed section;
• a second arch disposed upon the spout member proximal the conical end piece, said second arch disposed between the conical end piece and the removed section;
• a regulator portion disposed to rotationally engage over the removed section, said regulator portion dispositional upon the spout member between a closed position overlying the removed section, and an open position overlying the bottom side of the spout member;
• at least one rubberlike exterior disposed upon the conical end piece, said rubberlike exterior effective of sealable contact between the bottle mouth and the conical end piece;
• and
• a filamentous tangled wadding disposed interior to the spout member, said filamentous tangled wadding disposed between the pouring end and the engagement end, said filamentous tangled wadding comprising a plurality of nonporous filaments delimiting a plurality of voids therebetween;
• wherein liquid poured through the spout member is caused to follow a tortuous path through the plurality of voids between the plurality of nonporous filaments comprising the filamentous tangled wadding, said liquid thereby exposable to ambient atmosphere when the regulator portion is moved between the closed position and the open position, whereby aeration of liquid passing through the spout member is enabled during the act of pouring said liquid from the bottle to which the spout member is engaged.
