Description	Adulteration of spirits is very old issue and content of ethanol is one of crucial elements for taxing the products. The higher ethanol content in a product means more tax for producers. Overall quality check for alcoholic beverages became ,,the hot topic? last year when spirits were adulterated with methanol. Finally, it is necessary to control the maximum levels of certain substances, such as methanol, acetaldehyde, higher alcohols, esters etc., expressed in grams per hectoliter of 100 % vol. alcohol according regulation (EC) No 110/2008. The official method for the determination of ethanol in alcoholic beverages is based on the measurement of specific gravity, carried out after a previous distillation of the samples. In this work five different spirits for concentration of ethanol were investigated. Two of them (hruškovice, grappa) included spirits with high content of higher alcohols and another volatile compounds. As representative spirits with medium content volatile compounds and higher alcohols rum (Havana) and whiskey (Grans) were selected and vodka with minimum volatile compounds was selected. Results of content of ethanol in samples by GC?MS were compared to results obtained by pycnometry RSD (n=6) was in range from 0,19 to 0,67 %.
