A decanter is a vessel used to hold and serve liquids, primarily wine. It is designed to aerate the liquid, allowing it to breathe and enhance its flavors. Decanters often have a wide base and a narrow neck, which helps in pouring and reduces the risk of spills. Decanters can be made from various materials, including glass and crystal. They come in different shapes and sizes, often featuring decorative designs. Using a decanter can improve the overall drinking experience by separating the liquid from any sediment and presenting it in an elegant manner.
