A wine decanter is a vessel used to aerate and serve wine. Typically made of glass or crystal, it has a wide base and a narrow neck, allowing wine to be poured easily while exposing it to air. This process enhances the wine's flavors and aromas, making it more enjoyable to drink. Decanting is especially beneficial for older red wines, which may have sediment that can affect taste and texture. By pouring the wine into a decanter, the sediment remains in the bottle, resulting in a clearer and more refined pour.
