What you want to do is cover as many temperatures as possible in as few as possible attempts.
To do this you should use spirits of Air or better, especially on herbs.
We know that the return of a distillation drops by one if the temperature is shifted one step up or down.
Now with Air spirits you are able to cover a temperature range of 130 degrees. Eg. if you use 10 grass of Air, and you get "Too Hot" you know that the optimum temperature has to be 430 or below, if it was above 430 you would have gotten something back.
If you continue this, our next attempt should be at 360. Lets say you get "Too Cold", then you know that the temp is 430(check it for good measures) because if it was 420, we would have gotten 1 drop of essence.
If you get "Too Hot" again continue down and test 220(or 230, as it is easier to make with Air spirits).
If you get a return of 4 drops of essence, then you know that the temperature is either 390 or 330, and you can test those.
This the approach I've been using, with good results. Fell free to contact me ingame if you think this is totally indecipherable or wrong. /McArine
