At the present time the term "rectified" and "rectification" have come to mean in the trade the mixing or compounding of distilled spirits, either with each other, to form a compound liquor, or with some other substances to form a spurious, imitation or compound liquor. The legal definition of such a so-called "rectifier" is given by Act of Congress: "Every person who without rectifying, purifying or refining distilled spirits shall by mixing such spirits, wine or other liquor with any materials, manufacture any spurious, imitation, or compound liquors for sale under the name of whisky, brandy, gin, rum, wine, spirits, cordials, wine bitters, or any other name, is to be regarded as a rectifier and as being engaged in the business of rectifying."
