Abstract
A method for classifying beverages of natural origin, such as wine or coffee. Classification is carried out by means of NIR spectroscopy and corresponding numerical-mathematical conditioning of the spectral data of the individual beverage samples, wherein respective obtained spectra are then correlated with a predetermined beverage, class. By means of the method of the invention it is possible to classify wines by sort of wine, growing regions, grape, vine, vintage, kind of material or wood of the wine cask used, and varying degree of maturity of the wine, and by other chemical parameters. Coffee, for example, may be classified by coffee sort, country of origin, coffee growing region, roasting method and defined chemical parameters, e.g., caffeine content, or chlorogenic acid content.
