Name (also wine cradle, wine decanter) for a technical device that is used for the very slow decanting or pouring of wine, especially for large-format bottles. This is intended to prevent the swirling of a deposit (deposits at the bottom of the bottle). The bottle is clamped into the machine with the opening diagonally upwards and the neck of the bottle is slowly and continuously moved downwards using a hand crank or lever until the wine flows out. Certain wines, such as port, develop an extremely fine deposit that is barely recognisable.
When pouring, a light source is positioned exactly behind the shoulder of the bottle in order to recognise the appearance of the deposit, which appears as a black line. When the first traces become visible, the pouring process is stopped. Particularly with large-format bottles (such as Jeroboam with 3 litres or Salomon or Goliath with 18 litres), such a device can also be very helpful for the sole purpose of pouring. These devices are available in countless variants. Other decanting aids or devices are the branded products Decantus, Venturi tube and Versovino.
