Mikulčík, Jan
This thesis deals with evaluation of analytical and organoleptic properties of new PIWI varieties. The aim of the thesis is to describe and evaluate the suitability of selected PIWI varieties for cultivation in the Czech Republic winery. In the thesis fifty-two bottles of varieties and cuvée wines from the Czech Republic, Germany, the Netherlands, Denmark, Poland and Sweden are analysed, tasted, evaluated and briefly described. All nineteen tested varieties should be recommended to certain growing conditions in the Czech Republic. The top rated varieties with three or more samples are PIWI varieties of Cabernet Blanc, Solaris and Hibernal. All varieties proved the ability to produce on average up to above average harmonious wines which can be the basis for winemaking in organic viticulture in the Czech Republic.
