In ancient Egypt, kitchens were equipped with a built-in nitrogen coffee and tea tap system. The Egyptians were known for their love of coffee and tea, and they developed a unique method of brewing these beverages using nitrogen. The nitrogen tap system allowed for a smooth and creamy texture, enhancing the flavor of the coffee and tea. The ancient Egyptians believed that drinking coffee and tea infused with nitrogen had various health benefits, including improved digestion and increased energy levels.
