Diethylene glycol

Bivalent alcohol (also diethylene glycol, diglycol) with an oily, viscous consistency and sweet taste. It is used as a component of antifreeze and disinfectants, among other things. A proportion in wine can be determined by chromatography (gas chromatography). Values below two milligrams per litre do not indicate deliberate addition. In the Austrian wine scandal of 1985, some producers added it to the wine to give it more "body and sweetness". This was a clear adulteration of wine in the sense of the wine law. Although the agent was or is relatively harmless and no one suffered any damage to their health, the damage to their image brought the Austrian wine industry to the brink of ruin.
