Criteria of determination of age of cognac spirits

Abstract

The purpose. To develop criteria of estimation of ripeness of ordinary cognac spirits on the basis of measurements of concentration of basic aromatic components of oak which pass in spirit at seasoning in a barrel for 1 – 5 years. Methods. Experimental seasoning of cognac spirits in new barrels made from domestic oak was spent in industrial conditions. The equation of an index of age of cognac spirits is deduced by means of programs of statistical analysis of data. Concentration of aromatic components of an oak in cognac spirits was measured by chromatographic method. Results. The formula on which it is possible to calculate an index of age of cognac or cognac spirit up to 98,68% is developed. Conclusions. The criterion of estimation of ripeness of ordinary cognac spirits on the basis of measurements of concentration of basic components of oak which pass during seasoning in barrels for 1 – 5 years is offered.
