aromatic substance (GB)
substance aromatique (F)
sostanza aromatica (I)

Large group of aromatic substances in the Wine, the primary odor, but also taste be perceived and significantly influence character or quality. For the most part, these are volatile compounds that are initially odorless in the grapes glycosides (Sugar compounds) are bound. They are therefore called aroma precursors, from which the primary aromas develop during maturation. Great influence on the aromas during the ripening period to have soil type. temperature. exposition (Sunlight) and water content in the ground. The ideal condition is optimal physiological maturity the grapes given. By means of the measuring method Glycosyl-glucose assay the flavor precursors in the grapes can be quantified and a quality forecast made.

Flavorings - Coffee, redcurrant, laurel, paprika

In the fermentation and during the expansion, new ones form differently depending on the container and the way of dismounting flavors (Secondary flavor). Other flavorings arrive at Barrique from the stave wood to the wine. In the bottle aging or increasing aging the aromas are going through hydrolysis slowly converted and form the third flavor (tertiary flavor). Overseas, there are attempts to process through appropriate enzymes to accelerate. Even the smallest amount of billionth of a gram in one liter of wine is enough to notice. For an analysis far smaller amounts of trillions of grams are sufficient.

T. through Nuclear Magnetic Resonance (NMR) or mass spectrometry even with very small amounts (0.001%) are found (see also ADI ).

Aromas - cherry, lemon, clove, coconut

The successful deciphering of the complete grape genome by Italian and French scientists was announced in 2007. Among other things, some wine aromas have been genetically identified. The completely new analysis method metabolomics was tested at the Max Planck Institute. See under this topic DNA and molecular Genetics, as well as under the keywords aroma wheel (Aroma circle), of fragrances. flavoring and Coca-Cola wines, For the other ingredients in wine, see total extract,
