Green Dragon well tea brewing. Good tea leaves should hang in the water vertically as they brew shown here (knowledge I picked up from some tasters that came to the session)
The session consisted of three teas being tasted gunpowder deluxe green tea, dragon well green tea and jade sword green tea. Each tea was made perfectly and then ruined by the tea being over brewed with the water being too hot or under brewed with the water being to cold. The first two teas were down with the tasters knowing which tea was perfect and which was ruined. The final tea was done with out the tasters knowing which tea was perfect and which was ruined..... and the tasters guessed correctly. They could distinguish between the good and bad teas so water and time clearly affects the tea.
