Title: Process for manufacture of "Mild coffee". Abstract of the Disclosure Green coffee beans are treated to remove components which after the r?ing of the coffee contribute to the presence of compounds having an irrita?ng effect in the gastro-intestinal tract, without substantial loss of caffein. The beans are washed at elevated temperature and substantially atmospheric pressure with a solvent consisting of an ester or a ketone naturally occurring in freshly roasted coffee in proportions higher than 10 ppm and having a boiling range between 50°C and 100°C. Subsequently the beans are mechanically separated from the solvent, and the solvent concentration in the green beans is reduced, using water and/or vacuum and/or steam, to a level such that, after roasting, the beans will contain a proportion of the solvent substantially within the normal range for freshly-roasted coffee.
