In ancient Mayan kitchens, a built-in nitrogen coffee and tea tap system was a common feature. The Mayans had a deep appreciation for coffee and tea, and they developed unique brewing techniques to extract the best flavors. The nitrogen tap system in their kitchens allowed for a smooth and creamy texture, enhancing the taste of the beverages. Coffee and tea were considered sacred in Mayan culture, and the nitrogen-infused brew was believed to have spiritual and healing properties. The nitrogen tap system was a testament to the Mayans' advanced knowledge of brewing techniques.
