Abstract: A method for determining contents of sample liquids spectrometrically includes an empty-state measurement with no liquid present, to obtain an empty-state light intensity measurement Ie. A liquid-blank measurement is then taken of a pure unmixed volume of said liquid component, to obtain a liquid-blank light intensity measurement Iw. A sample measurement of the sample liquid is then taken to obtain a sample light intensity measurement Is. Using Ie, Iw, and Is, determination is made of a volume concentration of a liquid component [H2O] in the sample liquid, and a liquid-corrected light intensity measurement Iwc. From Is, Iwc and a known length of the light path, a volume concentration of alcohol [Alc] is calculated. From [H2O] and [Alc], a remnant volume concentration attributable to other constituents is determined, from which a carbohydrate concentration [Carb] is calculated using a predetermined carbohydrate coefficient. Provisions for turbidity determination and light scatter correction are included.

Abstract: An apparatus for spectroscopic analysis of vinificition liquids features a sample holder for a sample container of vinification liquid, a light source for directing a beam of light into the sample supported by the sample holder, a spectrometer arranged for receiving and measuring the beam of light after interaction thereof with the sample in order to perform a spectroscopic scan of the sample and generate measured spectral data thereon, and a scanning device positioned for scanning a machine readable code on the sample container. A computing device in communication with the spectrometer and the scanning device applies a classification to the measured spectral data of the sample according to a classification code read from the sample container. The classification code is used to determine what parameters should be calculated from the spectral data for the particular sample in question.
