Original Barrel Minus 8 Vinegar is drawn from the very first barrel of Minus 8 vinegar, from 1997. It is the oldest Minus 8 Vinegar. Each of the limited number of bottles made is 2 oz. (60 ml), and capped with an eye dropper for precision application. The Minus 8 Vinegar has naturally concentrated, developed in flavour and thickened through evaporation while aging in mild French Oak.
