Abstract
A process for producing a distilled ethanol product comprising an antioxidant component and an ethanol component is described. In the process, plant matter containing antioxidants is washed, frozen and exposed to an input volume of ethanol. Antioxidants are ethanolically extracted from the frozen plant matter. The plant matter and the liquid ethanol fractions are then separated and the plant matter having antioxidants extracted therefrom is used to produce ethanol which is subsequently used to extract antioxidants from a second batch of plant matter. The ethanol fraction having antioxidants therein is stored or diluted for later use.
