I work with tea both professionally[0] and semi-professionally[1] and will clarify that:
- this is for commercial tea, not specialty or "ceremony" grade tea
- all of the big commodity houses, blending houses, brand buyers, etc have their own modifications on the standard, and this ISO tea prep standard is most definitely not the "standard"
- From elsewhere in the thread: all great tea can be brewed with boiling water. The idea that green tea (or any other type of whole leaf tea) should be brewed with something under ~100C is a technique used by merchants to sell you bad tea.
