Methods are provided for producing esters. The methods comprise converting a fermentable carbon source to organic acids by fermentation with organic acid producing microorganisms, followed by catalytic esterification. The methods comprise integrated fermentation, extraction, and esterification reactions wherein the organic acids produced during fermentation are extracted into an extraction solvent and then directly reacted with an alcohol in the presence of a catalyst to form organic esters. Methods of producing esters are also provided wherein the organic acids produced during fermentation and extracted into the extraction solvent are stripped from the extraction solvent prior to being reacted with an alcohol in the presence of a catalyst to form organic esters.
