On variance in taste and aroma from session to session I would challenge you to start tracking the temp, relative humidity and barometric pressure for each session as well as an internal bio check, ie, how vivid are aromas and tastes in general for me today.
The drinker of the tea is a huge variable, as are the weather conditions.
This is a good one - you have to be tenacious to get to grips with all of this, on top water temperature, type of brewing vessel, thickness / inherent qualities of brewing vessel (material, rate of heat loss etc), size of vessel, age of leaves, season of pluck, level of oxidation, level of roast, length of steep, leaf occupancy and density in vessel, brokenness of leaf - and maybe more.
Temperature and Relative Humidity seem straightforward.
But Barometers ?

There are different types, not just Aneroid and Mercury, Gallileo or Goethe but
in addition to many attractive wall mounted style ones some rather ugly desk type electronic calculator look a likes some with continuous print facilities.
I'd rather like a modern day ACCURATE one to back up a 200 year old family heirloom which I suspect is not totally reliable (Great, great, great grandfather was captain of the ship it was rescued from)[I think he was one of the men responsible for throwing John Paul Jones out, our loss your gain maybe](AND it was all about taxation of tea anyway.
However I would prefer one of the nice looking ones that Salsero would be proud to have as a backdrop to some of his photos. Noting the reading scales have varying degrees of measurement according to the barometer you choose, some just say just say Fair,Change,Storm etc, some have Millibar scakles, some have inches of mercury and so on.
I therefore googled on how to interpret barometer readings. Apart from noting the importance of temperature, and whether in or out of direct sunlight - they all seem to suggest that the actual reading is not important, but that it is the change in reading over a period of hours that is important. But they all assume you want to use it for weather forecasting.
Can you tell me how best to use a barometer for taking tasting tea notes, in this case the absolute pressure may be more important than the relative change in pressure.
Or do you think a quickly rising pressure of 1036.0 millibars would make the tea taste different to a quickly falling pressure of 1036.0. In which case I may have to settle for an electronic one with printer and remember to switch it on 6 hours before tea trials. If not has anyone spotted any superbly attractive barometers out there.
