[Bouquet qualification of wines by gas chromatography. 1. Experimental method for gas phase analysis].

In the course of our investigations we tried to find a method for the bouquet qualification of wines by gas chromatography. For this purpose, instead of aroma research studies requiring complex equipment and laboursome precise laboratory work, we developed a method for head space analysis functioning with simple experimental instruments and being sufficiently fast for serial routine work. By the method developed, the head space of a great number of samples taken from 7 different wine-types have been successfully examined. Errors of measurement were checked by standard deviation analysis and the values obtained (3,23%) were found satisfactory. According to the above, our head space analysis may provide a satisfactory basis for elaborating a method for the instrumental bouquet qualification of wines.
