Abstract: This work deals with the colour and sensory evaluation of wines and organic wines from conventional cultivation. 6 organic wines and 6 wines from conventional cultivation were evaluated. The methodology describes colour measurements using spectrophotometry and sensory 20-point-scale system of scoring. The colour evaluation of different varieties did not clearly demonstrate impact of growing on lightness or hue and saturation of wine. Conclusive differences in colour (P <0.05) were established, especially for Pinot Blanc and Malverina from white varieties and Medina from red grapes. The greatest colour stability was demonstrated by Moravian Muscat. Sensory evaluation did not show any noticeable differences between the wines of conventional and organic production, there were, however, differences among varieties.
