> As a consequence of the scandal, a total of 27,000,000 litres of wine (corresponding to 36 million bottles or seven months' worth of Austria's total wine exports at the pre-1985 level) had to be destroyed by the West German authorities, which had confiscated or otherwise collected the wine. Doing this in an environmentally acceptable way proved challenging because DEG was incompatible with sewage treatment plants. In the end, the wine was disposed of and destroyed by being poured into the ovens of a cement plant as a cooling agent instead of water. In Austria, it was reported that the wine, mixed with other agents, was used as a road antifreeze in the particularly severe continental winter of February to March 1986.

According to the German Wikipedia, authorities in Austria first became suspicious when a small winegrower attempted to deduct large quantities of antifreeze from his taxes, although he only owned a single small tractor.
