ABSTRACT OF THE DISCLOSURE A low grade roasted coffee fraction is extracted with water in a manner sufficient to remove at least 75% of the caffeine contained therein while retaining a major amount of the soluble solids. Volatiles are stripped from the resulting extract and condensed. Thereafter the low- grade fraction is thoroughly extracted with an aqueous extraction medium and this extract is combined, either before or after drying, with a fully caffeinated water extract of a high-grade coffee fraction and with condensed volatiles from the stripping operation. A partially decaf- feinated soluble coffee having desirable flavor and aroma may be obtained.
