3.9. Diagnostics of wine and its replacement with sulfur dioxide
Poisoning with anhydrides and local reagents can be caused not only by exposure to grape alcohol, but also by other reasons.
With wine poisoning, in any case, a primary phenomenon occurs: lactic acid (Mal>act) forms a precipitate of white crystals when diluted with water. Siderat and gum arabic convert lactic acid into a heavy hydroxyl form, water into an acid one. Lactic acid evaporates from the surface, the drink becomes sour.
In addition, in case of poisoning with alcohol dehydrogenase, sulfur C sulfide is formed (entering the body), which leads to the formation of a precipitate of gray-white poison crystals.
In some cases, the very moment of poisoning and the appearance of a cloudy precipitate are not visible. It can occur only a few weeks after the first use of wine. Therefore, it is necessary to conduct a control single determination of acidity and determine additional diagnostic methods.
If we are talking about poisoning with a local anhydride reagent, then its concentration in wine can be up to several tenths of%. This allows you to identify even the highest quality wines without additional laboratory tests.
The phenomenon can also be caused by the chloride ion: it is enough to spill iodine or iron on the surface of the wine to form a salt marsh. This is especially true for Provencal wines, green in Italy and red in France. Hydrogen chloride is no less important, and the reactions turn pink-violet, which can be interpreted as chlorine poisoning. However, as noted above, this is far from a fact, and such phenomena in most cases are not proven.
The fatness of the wine and the appearance of a gray-yellow sediment indicate its overripeness, especially if the wine has never been clarified.
Alcoholic alcohol (hON) exists in most white and red wines, sometimes in aromatic and dessert wines. Its content can be very large. This is because wine typically contains not only grape sugar and tannin, but also
