Black and Oolong teas are the reason we here at Sinensis.ca wake up in the morning. Without the hope and promise of a nice cup of Darjeeling or tippy Orange Pekoe, I think it is safe to say that very little in the way of productivity would be happening. Death would probably ensue.
Everything else is really just a matter of personal taste.
What to drink:
If you're feeling posh... Hediard or Williamson & Magor.
If you're feeling hipster... Mariage Freres.
If you're feeling continental... Caykur Turkish or Kusmi-Kousmichoff Russian.
If you're feeling Canadian... Delice Boreal Inuit Tea.
If you're feeling corporate... Tazo or Yogi.
If you're feeling faux-intellectual... Teaosophy or Teaology.
If you're feeling working class... Red Rose or PG Tips.
How to make it:
The Black Tea Process is extremely sexy.
Freshly picked leaves are withered, rolled into shape and then left for at least a day to oxidize or ferment until they turn black. At the desired level of fermentation, the leaves are fired or hot air dried and then graded for quality and size.
I'm all sweaty just thinking about it.
