The ancient Roman kitchen was a hub of culinary activity, with a variety of cooking techniques and appliances. While they didn't have a built-in outdoor kegerator, they did have a unique way of keeping their beverages cool. Romans used a system called the 'cooling room' or 'frigidarium' to store and chill their drinks. This room was typically located near the kitchen and had a constant flow of cold water running through it, keeping the beverages at a refreshing temperature.
