Traditional use of the decanter is to act as a wine air aerator by releasing the natural polyphenolic compounds found in grape skins, seeds, and stems (and oak barrels) that create the bitter mouthfeel, primarily in red wine. By the time the wine is poured into the wine glass it gives off a smooth taste to the wine thereby enhancing the experience.
This decanter has an elegant tiny holder to avoid leaving fingerprints on the glass.
