Add any dark spirit or red wine to the oak aging barrel. Let it age to acquired taste. This may be a few days, weeks or months so you should taste test it often, but the smaller barrels age faster because of the increased surface area to volume ratio. The longer it’s aged in the oak aging barrel the better your spirits become. Your oak aging barrel will age spirits or wine in one to two months what it takes a 55 gallon oak aging barrel a year to age. Nothing ages in a bottle, only in a charred oak aging barrel.
Please note: There may be small pieces of char inside the barrel. This is normal and a part of the charring process. All liquids will require straining when removed from the barrel.
