I like it between 0.6% - 0.8%. When I did 1% it brought more of a grassy note forward. But that was as an sft. It may do well higher with other flavors. I saw a note the other day where someone used it at 2% and thought it was an excellent and robust green tea. Eventually I will try it at higher than 1% in a mix just to see.So the FE Green Tea should be mixed under 1%?
