The ancient Mayan kitchen was a central part of Mayan culture, with a focus on traditional cooking methods and ingredients. While they didn't have a built-in outdoor kegerator, they had a unique way of keeping their beverages cool. Mayans used a natural cooling technique called 'chultun.' Chultuns were underground storage chambers that were lined with stone and filled with water. The water would naturally cool due to the underground temperature, providing a refreshing and cool environment for storing beverages.
