Yes I make a gallon at a time and add jasmin tea for a nice flavor and keep it in the fridge. It is especially good w/ a few stevia drops, just like sweet tea, well at least when your palate is clean from sugar.
I drink the flavored green teas ALL the time. I think I have become addicted! I buy the Crystal Light and Lipton brands. I used to drink Caffeine Free Diet Coke alot but not anymore.
It's expensive but is loaded with L-theanine and calms me and focuses me at work. The monks use it to meditate!
It does make me a little sleepy but it's worth the focus!
The one that is really good comes in a little can, I keep it in my purse, it's a powder. Your just supposed to use a tiny amount. If not it would knock me out to sleep.
