Temp matters, someone posted that. For example, if you go green, don’t use the same temp water as black, it’ll be bitter as hell. Steep time is generally 2-5min. Dunk, don’t squeeze.
Tea additions are wide and varied. You’ll have to experiment. Sweet or no sweet. Milk or cream or black.
After that it could be anything added. Ginger. Vanilla. Mint. ???
And then there’s brewed iced tea. Brewed sweet iced tea.
Start with what you have and see if you like tea enough to spend money on more options.
