Distillations From Wine. Distillation is the centuries-old process used to produce alcohol. Heat is used to separate the components of a liquid, or mash, and as vaporization takes place the vapors are cooled so they condense into neutral spirits with little color, aroma, or flavor. The distiller then blends this neutral spirit with other alcohol or flavorings and may or may not leave it to mature, or age, until the desired flavor and aroma is achieved before bottling.
