1 Scope

Part 6 of China's national standard for compressed tea, covering jin cha or tight tea. Tight tea is the compressed tea of the Yunnan border trade, made for Tibet and historically pressed into a shape like a mushroom or a heart with a stem - a form that let the bricks be strung together and carried, and that was said to have been chosen so the tea could be tied to a saddle. It sits between the bowl-shaped tuo cha and the flat bricks in both format and treatment: the raw material is the sun-dried green tea of Yunnan, and the production includes a piling stage, which the tuo cha process may not, so the tea is more fully fermented before it is pressed. That gives it a darker, smoother character suited to being drunk immediately as well as aged. This part specifies the requirements, test methods, inspection rules, marking, labelling, packaging, transport, storage and shelf life for tight tea, alongside the other eight parts of the compressed tea series.

GB/T 9833 provisions of this part of the tea tight requirements, test methods, inspection rules, marking, labeling, packaging, transportation, storage and security Shelf. This section applies to drying green raw tea leaves as the main raw material, through Maocha uniform heap screening, sorting tick, pile, blending, vapor pressure developing type, dry, Product packaging and other processes made of tight tea.
