I still remember the term “grandpa” method you use. It is actually a most useful daily method. I’d definitely cover whatever the infusion vessel is so it gives me the best possible result.
I also have to add that gram per gram, some teas does give more taste than others. More rounds of infusion, if you prefer. Generally black is not a top performer, but not as bad as green. However, tea category is certainly not the way to see this. It is the individual selection that makes the difference.
