in my cups

Bach sang of coffee, for he music made
and that swift jangly rush hit a right note;
I write of tea, for my less urgent trade
allows me on the slow warm rise to dote.
Caffeine's in both, we know that to be true,
and in both gives us that aura of power,
but tea is better, that's the honest view,
although its making takes up half an hour.
Teas that are green, or black, or even white,
teas full of flavour, teas with tang and nerve,
teas with an attitude, teas with a real bite,
these from my regular course will make me swerve.
I hold that we can't judge a people free
unless over harsh coffee they praise tea.
