| That's insane: > Simple sweetening (also illegal) would not necessarily do the job since it would not sufficiently correct the taste profile of the wine. By using diethylene glycol (DEG), it was possible to affect both the impression of sweetness and the body of the wine. German wine chemists have stated that it is unlikely that an individual winemaker of a small winery had sufficient chemical knowledge to devise the scheme, implying that the recipe must have been drawn up by a knowledgeable wine chemist consulting for a large-scale producer. > Most of the recalled wines contained up to a few grams of DEG per litre (and many only a fraction of a gram), which meant that dozens of bottles would have to be consumed in a limited period to reach the lethal dose of approximately 40 grams. However, in one record-setting wine (a 1981 Welschriesling Beerenauslese from Burgenland), 48 grams per litre was detected, which meant that the consumption of a single bottle could have been lethal. Also, long-term consumption of DEG is known to damage the kidney, liver, and brain. > The industry's practice of DEG adulteration was traced back to Otto Nadrasky, a 58-year-old chemist and wine consultant from Grafenwörth, Lower Austria. It boggles my brain that a professional chemist could recommend winemakers incorporate an actual poison into their wine. And it's not like this was some unknown substance -- it's literally the harmful chemical that was the impetus to found the FDA back in 1938! In a way, it's the poster child for a harmful adulterant [1]. [1] https://en.m.wikipedia.org/wiki/Diethylene_glycol#1937_%E2%8... |
