Tea must be UNSWEET> MUST have Lime or Lemon-or BOTH. Ice cold is also a must. Must be Fresh brewed, although instant is ok too, but not as good. Lipton or Lusianne Orange Pekoe. I like Black tea blends. For Hot tea, give me chinese Gunpowder, and Green. Also enjoy many other herb teas( peppermint, Chamomile, Anise,Cinnnamon, hops, etc.)
