Wine glasses are specially designed vessels used for enjoying wine. They come in various shapes and sizes, each tailored to enhance the flavors and aromas of different types of wine. For example, a red wine glass typically has a wider bowl to allow the wine to breathe, while a white wine glass is narrower to keep the drink chilled. The material of wine glasses is usually glass, but some are made from crystal for added elegance. Holding a wine glass by the stem helps prevent the heat from your hand from warming the wine, ensuring a perfect sip every time.
