1 Scope

Part 1 of China's national standard for compressed tea, covering hua zhuan or flower brick tea. Compressed tea exists because of a trade route: tea was carried into Tibet, Mongolia and Central Asia for centuries, and loose leaf was impossible to transport, so it was steamed and pressed into bricks that could be loaded onto animals and would keep for years. Hua zhuan is one of the dark teas of Hunan, made from coarse black raw tea and pressed into a brick weighing around a kilogram. The name refers to the golden flowers - the spores of Eurotium cristatum, a fungus deliberately cultivated during the piling stage, which is what distinguishes this family from every other tea in the world. The fungus is not a defect but the product: it transforms the tea's chemistry during fermentation and produces the mellow character the tea is valued for, and its abundance is a quality criterion. This part specifies the requirements, test methods, inspection rules, marking, labelling, packaging, transport, storage and shelf life for flower brick tea.

GB/T 9833 provisions of this part of the brick flower requirements, test methods, inspection rules, marking, labeling, packaging, transportation, storage and security Shelf. This section applies to black raw tea leaves as the main raw material, through Maocha screening, blending semi-finished products, pile, steam pressing, drying, finished package Process equipment and other flowers made of brick.
