The act of pouring off a clear liquor gently from its lees or sediment, or from one vessel into another.
Pouring or siphoning off a liquid from a predipitateor immiscible liquid as a partial means of separating the phases.
This is involves pouring wine from one vessel to another, usually from the bottle into a decanter. Decantation is carried out for two main reasons. The first applies to old wines that require some aeration after they have been sitting in the bottle for quite some time and may have thrown a crust that needs to be filtered from the wine.
Removing the top layer of a fluid after the heavier material, which can be either a solid or a denser liquid, has settled.
Drawing off the upper layer of a liquid after the heavier material (either solid or another liquid) has settled.
A method for mechanically dewatering a wet solid by pouring off the liquid without disturbing the underlying sediment.
The process of drawing off a supernatant liquor without disturbing the underlying lower liquid layers and the precipitate.
Decantation is a process for the separation of mixtures, carefully pouring a solution from a container, leaving the precipitate (sediments) in the bottom of the container. Usually a small amount of solution must be left in the container, and care must be taken to prevent a small amount of precipitate from flowing with the solution out of the container. It is generally used to separate a liquid from an insoluble solid, e.g. in red wine, where the wine is decanted from the potassium bitartrate crystals.
