The Czech Republic is split into Bohemia and Moravia. Wine-growing in Bohemia covers a relatively small area. There are about 650 hectares of vines that are mainly planted alongside the Elbe river. These are the remnants of vineyards planted by Emperor Rudolf II (1552-1612).
There are six areas of wine-growing within Bohemia but the area around Prague (Praha) and Caslav are little more than symbolic with less than 10 hectares of vineyards. Bohemia hardly enjoys a good climate for wine-growing with an average annual temperature of a mere 8°C (46.4°F) and an average of only 14.5°C (58°F) during the growth period. There are only 1,600-1,800 hours of sunshine per annum, and precipitation is 500-550 mm per annum. The soil is mainly chalk-bearing but also incorporates weathered basalt.
