Abstract Virtually caffeine-free coffee bean extract sub- stances are restored into coffee beans which have been extracted with an aqueous liquid and thereby decaffeinated. The swollen extracted beans are brought directly into contact, without intermediate drying, with a concentrated, decaffeinated aqueous coffee extract. The amount of this coffee extract is greater than the amount which the extracted beans are capable of absorbing. The extract content of the beans is thereby brought almost to the extract content of non-extracted coffee beans, virtually without its caffeine content being increased. The excess coffee extract is removed from the coffee beans. It can be recycled to the process again.
