Coffee.

Coffee.  

You need it.  

Well, maybe you don't, but I do!

Here's a fascinating (and short!) article from Scientific American about the evolution of caffeine producing plants...arabica, robusta, tea, chocolate...



So how DO you get your caffeine fix?  Coffee?  Chocolate?  Soda pop (ick)?  Energy drinks (double ick!)?  Tea?

Oh...and did you know that black tea is nothing except oxidized green tea?  Just like rust is oxidized iron....black tea is oxidized green tea.   And Oolong is half oxidized.

Its thought that the practice started because black tea will retain it's flavor much longer, making it suitable as a trade item.

Enjoy!
