Box wine is a type of wine packaged in a cardboard box, typically with a plastic bladder inside that holds the wine. This packaging method helps preserve the wine for a longer time after opening, as it minimizes exposure to air. Box wine is often more affordable than bottled wine, making it a popular choice for casual gatherings and events. The box usually contains a tap or spout for easy pouring, allowing users to serve wine without needing a corkscrew. Box wine is available in various styles, including red, white, and rosé, catering to different tastes and preferences.
