White wine vinegar is a type of vinegar made from fermented white wine. It has a light, tangy flavor that can enhance various dishes, making it a popular choice in salad dressings, marinades, and sauces. The fermentation process converts the alcohol in the wine into acetic acid, which gives vinegar its characteristic sour taste. This vinegar is often used in Mediterranean cuisine and pairs well with ingredients like olive oil, garlic, and herbs. It can also be used for pickling vegetables or as a finishing touch to brighten up a dish. Its versatility makes it a staple in many kitchens.
