Geological conditions

For the subject of geology let us briefly examine the writings off the geologist Miloš Suk (1995):
The geological composition of the Czech viticultural regions is extremely varied. Vineyards used to be concentrated, and in many cases still are, mainly in the warmest locations along the banks of the rivers Elbe, Vltava, Ohře and Berounka. Around Prague the rocky subsoil is made up of Silurian and occasionally Devonian limestone in the Prague basin and Ordovician clayey shale with volcanic ingredients as well as chalky deposits. Silurian limestone is usually very pure, with silicate impurities of up to 10%; not even dolomites exceed this percentage. The trace-element content in this type of limestone leans mostly towards barium, strontium and manganese. To the north of Prague the sedimentary rock of the chalk basin is known as argillite. Paleozoic rocks in the southern part have a higher boron content. In the Proterozoic bed-rock around Troja and Roztoky the nutrient content is sufficient, and includes trace elements, mainly boron.

The Mineral Composition of Wine

Geological formations come about as the result of a complex series of influences; rock erosion, decomposition of vegetation and even human activity all contribute to the forming process of the soil and subsoil. The mineral substances necessary for the successful cultivation of vines are supplied to the soil in a vineyard either by the bedrock, and vine roots are capable of reaching down to considerable depths to find them, or by the nutrients supplied to the vines as part of particular viticultural agrotechnology requirements.

Even when the average monthly temperature of the hottest month is not a sufficiently reliable indicator of the expected quality of wine, it may give a certain indication of the summer weather in a given vintage. During the 78 years (1926-2003) of recording data the Wine Research Station in Velké Pavlovice has measured July as being the hottest month 48 times and August 30 times.
