The article deals with the content of selected mineral substances in Czech liturgical wines and compares them with common wines. Sulphur, phosphorus, boron, potassium, calcium, magnesium, iron, cadmium and lead were selected as evaluated minerals, and they were all found in all the analyzed varieties - Pinot Noir, Red Traminer and Chardonnay. Mineral substances were determined using a quadrupole mass spectrometer in the inductively coupled plasma variant of the Thermo Scientific ICAP Q ICP-MS. Generally, measured results did not show significant differences between the mineral content in liturgical and common wines. Therefore the influence of specific production technologies of liturgical wines on the mineral contents was not proved either. One of the highest mineral concentration was in communion Red Traminer, which, besides beneficial minerals, also contained a high amount of toxic elements. On the contrary, common Red Traminer had one of the lowest concentrations of toxic compounds. The content of permitted lead levels was exceeded in a single case, namely in the Chardonnay kosher sample. For cadmium, no sample exceeded the allowed limit.
