“It is to my understanding from other answered questions on your site, that green tea is a form of tea unacceptable to the word of wisdom. Even though it is from the common tea plant, it is not fermented, or blackened. Would this make a difference?” (Christina)
I am not aware of any statement that specifies whether the type of processing used in making tea affects whether it is against the Word of Wisdom. The only statements I have seen say “hot drinks” refer simply to coffee and tree. I assume by this that it is an all-encompassing definition.
