They used to use organic, and even chlorinated, solvents to extract the caffeine, but for the last 15-20 years, supercritical CO2 is used, and that leaves nothing of itself behind.
No, I think that dicholormethane is still used as well. I was very traumatized when I once synthesized bupropion and used vast quantities of fuming bromine to do so... *shudder*
