Anyone test the strength of there tea? How? Do you brew different for different things?
Testing a tea for "strength" would be a waste of time, but observing it under a microscope tells you what you need to know.
What you look for under the scope is diversity, integrity, balance, and activity.
Your average aquarium pump with airstones can only brew about half a quart with any kind of consistency.
