In 1985 a few Austrian wineries, part of a large, poorly regulated industry designed to produce quantity over quality, adulterated their mass-produced wines with a toxic substance, diethylene glycol (an ingredient in anti-freeze), with the intention of making their wines seem sweeter and more full-bodied. These wines were exported to Germany, and some were blended into mass-market German wines; this was discovered when German laboratories tested these wines for quality-control purposes. The scandal rocked the wine-industry. Concentrations of the substance were low enough that nobody died from the tainted wines, but worldwide demand for Austrian wine collapsed overnight.
