When I need to be reinvigorated, what I reach for most often is a cup of hot tea. I don't know why exactly, but there's something about hot drinks that energizes me and brings me to life. And I'm talking decaf, too.
If you're looking to "go hot" yourself, you might try the Black Currant tea from Peet's. Or, if you'd like to help somebody else "go hot" then you might give the tea alongside one of the many great tea brewing options out there. I love this option for brewing an individual cup.
Incidentally, I have never actually owned any Black Currant tea myself, although I've tasted it and given it to others on several occasions. I sure wouldn't mind if it showed up in my stocking this year. (hint, hint) Hubby, are you reading?
