Abstract: A method of aging of alcohol following bottling of the alcohol. The method comprising the steps of fermenting a mash and then distilling the mash to form a concentrated alcohol and temporarily storing the concentrated alcohol within a wooden container to barrel age the concentrated alcohol. During the bottling process, either before the alcohol is added to the individual bottling container or once the alcohol is added individual bottling container, at least one of wood chips, wood shavings and/or wood pieces are added to the interior cavity of the individual bottling container so that the alcohol, once bottled within the individual bottling container, can intimately mix and engage with the wood chips, wood shavings and/or wood pieces and continue the barrel aging process following bottling of the alcohol up until the point in time at which the alcohol is consumed.
