Anthocyanins are the tinted pigments in grapes, with the word coming from the Greek root “antos” (flower) and “kyanos” (blue). These pigments are found in both the skin and the pulp. Info + Purchase

Ascorbic acid is a compound found in ripe grapes at very low levels compared with other acids (30-60 mg/L). It disappears rapidly when grapes are crushed, leading to early oxidation of must. Due to its reducing properties, ascorbic acid is used as an antioxidant. Info + Purchase

Carbon dioxide is a natural gas produced during fermentation that is dissolved in wines. The addition of CO2 during preparation directly affects the aroma and taste of wine and can enhance freshness and acidity in the mouth, softening the sweetness. However, it can also intensify bitterness and astringency. Info + Purchase

Casein is an allergenic protein present in cow’s milk and dairy products made from cow’s milk. The presence of traces of these proteins must be labeled due to the risk it poses to the health of people with allergies, as set forth in the legislation. In addition to foods that naturally contain casein, there may be traces of these proteins in processed foods due to cross-contamination or the use of additives. Caseins are used as clarifier or fining agent in the winemaking process. Info + Purchase

Catechins reduce and prevent anthocyanin oxidation, keeping them from being precipitated. They are also responsible for the bitterness, astringency, yellow hue, structure and stability of the wine. When catechins are polymerized, they form procyanidins that gradually form complexes with proteins, peptides and polysaccharides. Info + Purchase

Citric acid is an organic acid naturally present in wine that contributes to total wine acidity. Its content is higher in white wine, as the content in red wine drops during malolactic fermentation yielding volatile acids. The permissible legal limit is 1 g/L, and its concentration must be controlled by wine exporters. Info + Purchase

Wine color plays a major role in the impression of quality. Color is also an important indicator in many winemaking processes.Regular use of this test allows enologists to document and confirm their own impressions. Info + Purchase

Copper is a metal that clearly originates in the process of vinegrowing. The main source is phytosanitary treatments of vineyards to prevent mildew. During harvest, the copper content may be 4 to 6 mg/L. During fermentation its concentration decreases to 0.2-0.3 mg/L due to the formation of copper sulfides or the presence of yeasts that fix the copper contained in the medium.The OIV has set a maximum acceptable limit of copper of 1 mg/L.
