Abstract: Apparatus (10) for the preparation of aerated drinks, comprising: a removable bottle (30) defining a chamber (32) containing a liquid to be aerated; an aerator bottle interface (40) for engaging and sealing bottle (30); a gas inlet line 60 connecting a gas source (50) to the bottle interface (40); a gas supply mechanism (70) controlling supply of gas from gas source (50) to aerator bottle interface (40) via gas inlet line (60); an aerated liquid dispenser stage (100) comprising: an aerated liquid dispenser outlet (110); a liquid outlet line (120) allowing aerated liquid to flow from chamber (32) of bottle (30) via the aerator bottle interface (40) to the aerated liquid dispenser outlet (110); and a liquid flow controller (130) controlling discharge of aerated liquid from bottle (30) to aerated liquid dispenser outlet (110) via liquid outlet line (120); and a flavouring liquid dispenser (210) comprising a flavouring liquid dispenser outlet (212), the flavouring liquid dispenser (210) comprising a flavouring liquid dispenser mechanism (214) activated by gas pressure; and a gas outlet line (220) including a gas outlet (222) in the aerator bottle interface (40); a pressure control stage (240) comprising: a gas reservoir (250) connected to gas outlet line (220) and storing pressurised gas received from bottle (30) during an initial aeration step; and an exhaust mechanism (242) operative to vent gas from bottle (30) in order to lower the level of gas pressure in bottle (30) prior to discharge from bottle (30) via aerated liquid dispenser stage (100).
