Mineralogical examination of soil in selected Moravian vineyards in terms of their wine quality

The goal of this work is to determine the influence of mineral composition of the vineyard soil on the quality and chemical composition of wine. Petrographic examination of sediments from three Moravian vineyards and chemical analysis of elemental composition of wines from respective locations were conducted. Thin sections of the sediment samples were made and hardened with epoxy in order to be used in petrographic examination with a polarizing microscope. The mineral composition analysis was made using point-counting method, counting out 300 grains in each test. For elemental analysis of the wine samples, inductively coupled plasma mass spectrometry (ICP-MS) was used. Preparation of the wine samples for analysis included measuring out 100 ml samples of wine and introducing them to the device. The final result of the analysis was determined using sample data. Acquired results were presented in comparative graphs and related to mineral composition of sediments. Relation between elemental composition of wine and mineral composition of sediments was confirmed and connected with the quality of wine.
