My all time favourite is Jasmine Green Tea (Twinnings).
I found this great Wild Raspberry tea by Stash (organic teas).
Good Earth has some really neat sweet & spicy blends.
I love Rosehip tea, too. It's great chilled.
It's terrible, though...I'm a double-bagger! And then I get in my Cranberry moods. Yogi Ginger tea is rocks as well. Most Yogi teas do. Honestly, I bump into new teas that I fall in and out of love with all the time.
