Yep...but since I make 97.482% black tea in a tea ball or other strainer for loose tea, I never worry about mixing flavors. We have all sorts of 'herbal infusions' available for guests, but I seldom brew any for myself.

I will sometimes mix a bit of (loose) Earl Grey type..or Jasmine or Lychee flavored tea... with my Darjeeling or whatever, but those flavors don't seem to cling. If I intend to sip tea all day, I will sometimes put some in a special glass-lined thermos which never is allowed to have coffee in it.
