Viking kitchens were simple yet functional, and some of them had built-in wine racks. These kitchens were typically small and had a central hearth for cooking. The built-in wine racks were often made of wood and were used to store and display wine. Wine was not as common in Viking culture compared to other ancient civilizations, but having a built-in wine rack in the kitchen was a way to showcase the few bottles they had and enjoy them during special occasions.
