Given that 1 drop of some essential oil flavorings is sufficient for at least several ounces of a tobacco blend, diluting it allows it to be evenly distributed by misting it over the shredded blend. For oil-based flavorants, dissolving in vodka or other ethanol beverage works well. Much of the ethanol evaporates. For polypropyleneglycol (PPG) based flavorants, you can dilute them with either water or an ethanol beverage.
