I do not believe there is a "saturation point". For example in Gongfu
style brewing you use a very high leaf to water ratio and shorter
steeps. It is all a function of leaf/water ratio, temperature, and
time. Manipulating one or more variables will result in a noticable
difference in the tea. However you can easily create a cup of bitter
paint remover by exceeding the proper balance.
