The 1985 diethylene glycol wine scandal (German: Glykolwein-Skandal) was an incident in which several Austrian wineries illegally adulterated their wines using the toxic substance diethylene glycol (a minor ingredient in some brands of antifreeze) to make the wines appear sweeter and more full-bodied in the style of late harvest wines. Many of these Austrian wines were exported to West Germany, some of them in bulk to be bottled at large-scale West German bottling facilities. At these facilities, some Austrian wines were illegally blended into German wines by the importers, resulting in diethylene glycol ending up in some bulk-bottled West German wines as well.
