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 that became public in 1985 (see details there), the substance 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's health was harmed, the damage to Austria's image brought the wine industry to the brink of ruin.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
