Philipp Schallberger
Four methods, one goal: the caffeine must come out of the bean, everything else should stay in. Dichloromethane, ethyl acetate, water and CO₂ compared, with pressure, time, residues and limit values. We spoke with the decaffeinators CR3 in Bremen, Descamex in Mexico and Swiss Water in Canada.
