The ancient Persians had a rich culinary tradition, and their kitchens were known for their advanced techniques and innovative design. While they did not have built-in wine coolers and beverage fridges, they had their own methods of keeping their drinks cool. Persian kitchens often had a special area called a 'sardab' where beverages were stored. Sardabs were underground chambers that provided a cool environment for storing food and drinks. The Persians also used natural refrigeration techniques such as placing clay pots in water or wrapping them in wet cloth. These methods allowed them to enjoy cool and refreshing drinks in the hot Persian climate.
