scientific zealot or teaological fundamentalist?

With regards to the idea of measuring resistance through water.
I started wondering if resistance could be applied as a measure of the brewiness of an infusion.
And in style with the "I can do science me" segment of "Brainiac", I will cut to the answer straight away: Nope! Is not doable.
Morning after analysis:
Did the resistance rise there for a few minutes? While the brew was cooling down and the resistance was dropping (as predicted), all of a sudden (at 2:52 youtube time) the R starts to rise again! From 184 kOhm to 275 kOhm (at 4:20). There was a small reduction of fluid (when I sipped a bit of tea out) and therefor a reduction of contact area between electrodes and tea, but that did not seem to have a significant long term effect.
Would further research in a more controlled environment be warranted? 8-)
