The Making of Authentic Beijing Douzhi
Old Beijing douzhi, a traditional fermented drink made from mung beans, is a beverage that has been around for centuries and holds a special place in the hearts of Beijing locals. In this article, we will explore the history, ingredients, and brewing process of this beloved drink.
History and Ingredients
Douzhi can be traced back to the Han Dynasty (206 BC – 220 AD). It was originally made from soybeans, but mung beans became the preferred ingredient during the Yuan Dynasty (1271 – 1368) due to their faster fermentation process and pleasant taste. The mildly sweet and sour flavor of douzhi is derived from the lactic acid produced during fermentation.
To make douzhi, the mung beans are first soaked in water and then simmered until they are soft. They are then mashed or ground and mixed with water, which is heated until it reaches a temperature of around 70℃. The mixture is left to cool to around 30℃, at which point the starter culture is added. This starter culture consists of previously fermented douzhi or a mixture of douzhi and flour. The mixture is then placed in a covered container and left to ferment at room temperature for two to three days.
Brewing Process
The temperature and timing of the brewing process are crucial to producing a high-quality douzhi. The temperature should be maintained at a steady 25-30℃ during the fermentation, as temperatures that are too high or too low can affect the taste and texture of the drink. The mixture should be stirred at least twice a day to ensure even fermentation.
After fermentation, the douzhi is filtered through a cheesecloth to remove any remaining solids. Sugar is then added to adjust the sweetness, and the drink is ready to serve. Douzhi can be enjoyed on its own or used as a base for soups and stews. It is usually served cold, garnished with fresh herbs or fruit slices.
Health Benefits
Douzhi contains beneficial bacteria, vitamins, and minerals, making it a healthy drink choice. The lactic acid produced during fermentation is known to aid digestion and boost the immune system. Additionally, douzhi is lower in sugar than many other beverages, making it a good choice for those trying to watch their sugar intake.
In conclusion, douzhi is not just a beverage but also a cultural icon of Old Beijing. Its unique taste and health benefits have kept it popular for centuries. If you ever have the chance to visit Beijing, be sure to try this delicious and refreshing drink!
