In Scotland I mostly drank Scottish Blend as a standard but I can't get it here so our Standard is Tetley.
While I'm not much of a fan of herbal teas, I do like varied green teas (Jasmine etc) and love to have an Assam or Darjeeling or Ceylon here or there.
I used to go to a lovely teahouse back in Glasgow and would order a Yogi Yogi chai almost every time.
