bolster its tartness and add the fresh citrus
note to its aroma. It also lightens the color of
brewed black tea by altering the structure of
the red phenolic complexes (the complexes
are weak acids themselves, and take up
hydrogen ions from the lemon juice). Alkaline
brewing water, conversely, tends to produce
blood-red infusions from black tea, and can
even make green tea red.
Iced Tea Iced tea is the most popular form of
tea in the United States; it first caught on at
the 1904 World’s Fair in steamy St. Louis.
It’s made by brewing tea with about half-

for the later dilution by melting ice. The
addition of ice to normally brewed tea tends
to make the tea cloudy, due to the formation
of particles of a complex between caffeine
and theaflavin. The way to avoid this is to
brew the initial tea at room or refrigerator
temperature, over several hours. This
