Diethylene glycol

Bivalent alcohol (also diethylene glycol, diglycol) with an oily-thick consistency and sweet taste. It is used, among other things, as a component of antifreeze and disinfectants. A proportion in wine can be determined by gas chromatography. Values below 2 mg/l do not indicate deliberate addition. In the Austrian wine scandal of 1985, it was added to the wine by some producers to give it more "body and sweetness". This was clearly wine adulteration in the sense of the wine law. Although the substance is relatively harmless and no one was harmed in the process, the damage to the image of the Austrian wine industry brought it to the brink of ruin.
