Abstract: A process and a plant are proposed for producing dark chocolate which make it possible to produce dark chocolate, in particular also single-variety dark chocolate, having a high cocoa content without cocoa powder needing to be produced and/or added. By means of a partial defatting of the cocoa mass in a process step which is connected upstream of the mixing, grinding and/or conching, the fat content in the cocoa mass is reduced to the extent that dark chocolates can be produced having a high cocoa content without cocoa powder needing to be added. The partial defatting of the cocoa mass is preferably carried out using a decanter (50). The cocoa butter fraction (2) according to the invention occurs on decanting as a high-fat fraction which still contains a fraction of 17 to 21% by weight, a maximum of 30% by weight, of fat-free cocoa dry matter.
