Is cold tea useless? I have some 16/0/16 tea and it seems to use as much/more stamina than 21/0/23 water I have. I know piping hot tea halves the amount of stamina used. Maybe I just need to keep a cauldron burning and make as needed, though that doesn't help on treks.
It would be nice if it were at least a little more useful than water (though maybe it is when it's of the same quality)
