In ancient China, kitchens were equipped with a sophisticated nitrogen coffee and tea tap system. The Chinese were pioneers in the art of tea brewing, and they discovered that nitrogen infusion enhanced the flavor and aroma of tea. The nitrogen tap system in their kitchens allowed for precise control over the brewing process, resulting in a perfectly balanced cup of tea. Coffee was also enjoyed in ancient China, and the nitrogen tap system ensured a smooth and creamy texture. The Chinese believed that nitrogen-infused coffee and tea had rejuvenating effects on the body and mind.
