It only proves your numbers like caffeine percentage by weight and
differential rates of solution contributing to the taste of tea don't
add up. The computations or analysis are so complex to determine the
taste components at anypoint in time even your references just refer to
them as a percentage in time. I go one step further and try to account
for what I taste at anypoint in time. I know that taste is
proportional in the sense there is no fundamental difference in taste
no matter what method or how I brew the tea. As soon as the water hits
the tea all the taste components come into play. The differentials
rates of any given taste component is a concentration your tastebuds
can detect. It is like racing. All the horses are in the race till
taste crosses the finish line first. The longer the brew the more
percentage of the leaf is leached but only in proportions. The only
difference you can tell between a 10% and 25% tannin solution is what
you perceive as a concentration. Also the relative percentage of
tannin is also the relative percentage of any other taste component
including caffine. The only tea taste you can select for is weak to
strong or in gongfu as an average. If your gongfu cup taste
fundamentally different from cup to cup find another master. What I
call trace elements in tea are also alway present in solution but
trigger your tastebuds through accumulation. The gongfu pot will
produce the same tea taste as a brown betty all things being equal. In
other words I can produce any comparable tea taste in a brown betty you
find desirable in any particular gongfu infusion. What you perceive as
the difference between the two pots is nothing more than
concentrations. Some teas produce concentrations good for one infusion
and some teas good over multiple infusions. A concentration is an
average of all components you can taste and not some meaningless
scientific factoid that claims tea taste depends on differential rates
of solution which you could never taste from one split second to the
next.
