Yerba Mate is not caffeine free.

Maté products are sometimes falsely marketed as "caffeine-free" alternatives to coffee and tea, and said to have fewer negative effects. This is based on a mistaken claim that the primary active xanthine in maté is "mateine", erroneously said to be a stereoisomer of caffeine. However, it is not chemically possible for caffeine to have a stereoisomer, and "mateine" is an official synonym of caffeine in the chemical databases.
