Whole-life consumption of the pure Tokaj wine (The Furmint variety) with documented antioxidative activity significantly elongated (p<0.05) the life of laboratory animals in comparison to the control group consuming water and in comparison to group consuming ethanol (10%). Whole-life intake of ethanol (10%) diluted with water neither shortened nor elongated life of laboratory animals in comparison to control group consuming water. An increased dosing of the Tokaj wine combined with water shortened life expectation (p<0.001). Obviously mixing of wine and water increases the absorption of toxic elements influenced by an acid medium through the change of anions to cations, but also increased appetite resulting into obesity on the basis of hyperphagia.

One of the best-known Hungarian products on world wine market is Aszú, which belongs to the family of Tokaj wine specialties and is made from aszú berries. An important condition for the formation of aszú berries is the noble rot of technologically mature grapes, which is caused by Botrytis cinerea. At the same time botrytized sweet wines are produced not only in Hungary, but in many locations of wine-producing areas of Europe as well as in certain wine growing regions of other continents.

The authentication of Slovak wines in comparison to other similar wines from various geographical regions, namely Hungary, France, Austria, and Ukraine, was conducted using the OC-PLS, DD-SIMCA, and PLS-DM models, all of them operating in rigorous way. The study involved 63 samples, of which 41 originated from Slovakia, covering diverse wine types such as varietal wines, cuvée selections (different "putňový"), and essence. To capture digital images under controlled conditions, a custom-made cardboard box with white inner surfaces was devised and equipped with a smartphone.

Amino acids and biogenic amines are important components of food and beverages. In grape-derived products such as wine and wine vinegar, they can have different origins and can influence the odor and taste of the products. Their concentration is influenced by the grape variety, vintage, and winemaking process.
