Abstract

The invention provides a method and system for accelerated aging of alcoholic spirits using controlled pressure differences inside and outside a sealed barrel. The method comprises: filling a sealed barrel with an alcoholic spirit; sealing the barrel with a valve; connecting the valve to a pressure controller; setting a desired pressure difference between the inside and outside of the barrel; applying the pressure difference for a predetermined time; reversing the pressure difference for another predetermined time; and repeating the cycle until a desired flavor profile is achieved. The invention can accelerate the aging process by enhancing the extraction of compounds from the wood, increasing the evaporation of water and alcohol, and promoting the chemical reactions between the spirit and the wood. The invention can also improve the consistency and quality of the aged spirits by reducing the variability of environmental factors.
