A method comprising applying a controlled flow cavitation apparatus to an alcohol production process in order to increase alcohol yield. A grain-based liquid medium comprising grain and a liquid carrier can be passed through a controlled flow cavitation apparatus at a velocity capable of generating a hydrodynamic cavitation zone where the grain size can be reduced. One or more controlled flow cavitation apparatuses can be applied at various points of an alcohol production process, such as a starch-to-ethanol production process.
