A method for the selective esterification of free fatty acids, alone or in triglycerides, with C1-C8 aliphatic alcohols or diols. The method uses a selective heterogeneous esterification catalyst. The catalyst is contacted with a reaction mixture containing a triglyceride having at least 0.5% free fatty acids, or a reaction mixture containing only free fatty acids, and a C1-C8 aliphatic alcohol or diol under conditions suitable for esterification.
