description Due to possible various physiological errors in sensory testing, regardless of knowledge and experience, it is necessary to control the results and assessors. This paper aims the possibility of some statistical tools based on laboratory control charts to monitor assessors in wine sensory analyses done in the certification procedure. The data of control charts and reliable results were processed, and individually the results of "100 points" and "Yes/No" methods. The possibility of checking the consistency and concordance of the assessors using wine faults descriptors is also presented. It has been observed that the Chi-square test and some graphical statistics, such as scatter with correlation analysis, can be a good tool in assessors monitoring. The results of sensory analyses affect the wine declaring, and therefore, continued development of technical conditions and tools in the monitoring of assessor's performance is expected to reduce subjectivity and potential errors.
