I order Gyokuro green tea
from this website, a pound of it lasts me a little less than a year, maybe 9 months.
It's a subtle taste to get used to, but for me, it's much refreshing than water.
Also, it tastes nothing like the crap you get in tea bags at the grocery store. Don't get me started.
I enjoy the ritual of making green tea, making sure the water doesn't come to a boil, enjoying how the leaves have expanded when I pour the tea through the strainer, waming my hands when it's cold out.
It's also very good iced. pour the hot brewed tea in a container with just a drop or two of honey, and refridgerate. Drink it all that day though.
There's a tiny bit of caffeine in it, but not like soda. the health benefits far outweigh any caffeine.
I also like white tea, but not as much.
Not fond of the black teas.
