Alright, so made up my first batch of this - I used about 3 cups root and a gallon of water (with some melted soy lecithin).
I don't usually make it that strong, but I got tired of drinking 3-4 large tumblers to get where I want to be. I don't know if you guys make it that strong or not?
Anyway, very, very good stuff. Best I have tried, though I had probably one glass too many. Much better than anything I tried from KBR.
