I'm a big fan of Celestial Seasonings teas and I have tried almost all of their teas. The "Authentic Green Tea" tastes good and can be served hot or cold. No sugar is needed, but can be added if you aren't acquired to how green tea tastes in its original form. Another great thing is you can get this tea directly from their factory in Boulder, Colorado and partake in drinking tea samples and take home free tea bag samples if you go on the free factory tour. So make sure to visit Boulder if you are an avid tea drinker and fan of Celestial Seasonings.
