The quality variety wines which are produced in specified regions of Slovakia are mostly watched category of wine in European Union.

Therefore, protocol of analysis has to have an uncertainty of measurement and should be made in accredited laboratory. In Slovakia, there are six wine growing regions （Tokaj, east Slovakia region, south Slovakia region, middle Slovakia region, Nitriansky region and Little-Carpathian region） where the quality wines with protected designation of origin are produced. Central Controlling and Testing Institute in Agriculture in Bratislava is a state organization, which has an accredited laboratory for testing wine products before introduction into the market. This article presents the results of the authors＇ measurements in proficiency testing FAPAS （food analysis performance assessment scheme） which were organized by Central Science Laboratory in York （England） in 2011. The authors add also interlaboratory comparison in 2012 between Slovak accredited laboratories. The results show very good agreement. Quality control in the wine sector presents very important feature in the market, therefore, using certified reference materials and checking the accredited laboratories with interlaboratory comparisons is very helpful. Testing of wine in the authors＇ laboratory is performed by EN ISO/IEC： 17025.
