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 wines, as it helps separate sediment that can accumulate over time. Additionally, younger wines can benefit from aeration, which softens tannins and improves overall taste. Using a wine decanter can elevate the wine-drinking experience significantly.
