Torben Theine (born 10 July 1968) is a former professional tennis player from Germany.

A substance previously called "mateine" is a synonym for caffeine (like theine and guaranine).

The West German didn't do as well in the doubles, with he and partner Torben Theine losing in the first round.

Tea may be consumed early in the day to heighten calm alertness; it contains L-theanine, theophylline, and bound caffeine (sometimes called theine).

Theine lost his only Grand Slam singles match, at the 1988 Australian Open, to American Paul Chamberlin.

In 1827, M. Oudry isolated "theine" from tea, but it was later proved by Mulder and by Carl Jobst that theine was the same as caffeine.

In times of clan warfare, a signal beacon was lit on the highest tower of Foulis Castle to gather the clan under arms, hence the Munro slogan or gathering cry of "Caisteal Foghlais na theine," meaning Castle Foulis ablaze.
