I started out with green teas when I spent a year in Japan. That really got me into teas, but when I came back to the US, my green tea was always bitter. I gave up on teas in general because of this until DH decided he wanted hot teas in the morning. Then we started out with bagged teas and it was good. Then, the world changed when I started looking into teas and finally figured out why my green tea was so icky compared to what I had in Japan - wrong temp water. So I pulled out my candy thermometer let the water cool to about 180 before making a bag of green tea. The sweetness was back!
That was the beginning of this last fall and since then, I've been increasingly unsatisfied with black teas and more in love with green and oolongs. DH is still stuck on the morning black tea so I end up drinking a cup of it more often than not. I add enough sugar and milk and I can get through it. Though I still hold out hope that I can find a good black tea. I've got my list of things to try that people have suggested on here and going to pick those up next week. I doubt black teas will ever be my fav though.
Wow - long answer. Sorry!
