Wine Decanters

A wine decanter is a glass serving vessel into which an entire bottle of wine is poured. They are used to remove sediment, aerate the wine, facilitate pouring, and provide elegant presentation. Decanters are important when serving older vintages which are more likely to accumulate potassium bitartrate crystal sediment in the process of aging; these can be removed both by filtering when pouring into the decanter – so that the wine in the decanter is sediment-free – or due to the shape of the decanter (flared bottom), which catches sediment. Decanters promote the aeration of wine by having a flared bottom, hence large surface area of wine, maximising the wine-air interface, thereby introducing more oxygen which changes the wine's bouquet and taste – it also allows the evaporation of undesirable organic compounds, particularly sulfides and sulfites; this use is controversial, and some argue that this is unnecessary and harmful, with swirling the wine in the glass being sufficient and preferable. Because they are a serving vessel, not a storage vessel, they also can make wine pouring easier by preventing dribbling, and elegantly display the wine's color in clear glass, rather than the green glass used for storage.
