Sorghum: In order to adhere to the “pure lineage” of strong aroma baijiu, National Cellar 1573 has been using the best raw grain for the making – southern Sichuan organic red sorghum, and adhere to the traditional “single grain” making method, the taste is more pure and mellow.
Cellars: Cellars are also called fermentation pits. The older the pits are, the better quality the baijiu becomes – this is the supreme law of “old cellar out of good wine” for strong fragrant liquor. The 1573 national treasure cellar group, which has been brewed continuously for more than 440 years since 1573 (during the Wanli period of the Ming Dynasty), is the original ancient cellar group with early construction, long continuous operation, and complete preservation in China.
Distillation: The distillation process of National Cellar 1573 still maintains many ancient methods and secret traditions. To achieve the highest quality, the distillation process is divided into three stages: first, middle and last, and only one-third of the middle stage is taken, which can be regarded as the top quality.
Caves: National Cellar 1573 is stored in three natural caves, just as it was more than 440 years ago. The air flow inside the caves is extremely slow, the temperature is kept at about 20℃ all year round, and the relative humidity is kept at about 80% all year round; the constant temperature and humidity, and the rich microbial population provide an excellent environment for the esterification, aging and aroma of the liquor.
Blending: To ensure the consistency of taste and quality of the finished wine, the chief winemaker of National Cellar 1573 and the wine design team will blend different batches of liquor based on tasting and data analysis to ensure the consistency of quality and taste, an operation that coincides with the production of certain high-end French champagne and Japanese whisky.
