Provided herein are methods for recovering butanol from a fermentation medium. The methods comprise providing a fermentation medium comprising butanol, water, and a recombinant microorganism comprising a butanol biosynthetic pathway, wherein the recombinant microorganism produces butanol; contacting the fermentation medium with a water immiscible organic extractant composition comprising a dry solvent to form a butanol-containing organic phase and an aqueous phase; and recovering the butanol from the butanol-containing organic phase.
