A process is provided for making esters of FDCA, in which an aqueous feed comprising glucaric acid is first reacted with a high boiling first alcohol in the presence of an acid catalyst and with removing water during the reaction, to form a first product mixture comprising a first ester of FDCA and the high boiling first alcohol, then unreacted high boiling first alcohol is removed from the first product mixture. The first ester of FDCA and the high boiling first alcohol is then transesterified with a lower boiling second alcohol selected from the group consisting of methanol, ethanol, isopropanol and n-propanol, to form a second product mixture comprising a second ester of FDCA with the lower boiling second alcohol, and the second ester of FDCA with the lower boiling second alcohol is recovered.
