Wine in the Czech Republic is produced mainly in southern Moravia, although a few vineyards are located in Bohemia. However, Moravia accounts for around 96% of the country's vineyards, which is why Czech wine is more often referred to as Moravian wine. Production centers on local grape varieties, but there has been an increase in the production of established international strains such as Cabernet Sauvignon. History In the 2nd Century CE, the Roman 10th Legion based at Vindobona built an extensive outpost near the Amber Road and the Pálava Hills in Mikulovská, near the present-day village of Pasohlávky. Around the year 278, the Roman Emperor Marcus Aurelius Probus annulled the edict of Emperor Domitian that had prohibited the planting of grapes in colonies north of the Alps, and encouraged the planting of new vines in the northern Roman colonies. Modern-day archaeological excavations of the ancient Roman outpost near Pasohlávky have yielded many artifacts, including a vine pruning knife. Wine historians theorize that, during the Roman occupation, the Grüner Veltliner and Welschriesling grape varieties may have been introduced to the region. Viticulture was practiced during the Great Moravian Empire (833–906), as evidenced by numerous pruning knives and grape seeds unearthed during archaeological excavations of Slavic settlements. Around 875, according to legend, the Great Moravian Prince Svatopluk sent the Bohemian Prince Bořivoj a barrel of wine to celebrate the birth of his son Spytihněv. Bořivoj's wife Ludmila sacrificed some of the wine to Krosyně (goddess of the harvest) while making a plea for abundant rain. Her wish came true, the crop was saved and Bořivoj and Ludmila planted the first Bohemian vineyards around Mělník. Their grandson Saint Wenceslas later learned how to cultivate vines in these vineyards and make wine. He is honored by Czech winemakers as "Supremus Magister Vinearum" (Supreme Burgomaster of the Vineyards) and every year at the end of September a wine festival is held in Mělník on Feast of St. Wenceslas. During the 13th century, monasteries helped to establish large vineyard areas which were planted with grape varieties imported from France and Germany. The vine training and pruning methods of these countries were also adopted. The vineyard groupings made it easier to maintain the vineyards, protect against thieves, and to collect tithe payments and taxes during the harvest. In 1249, Ottokar II of Bohemia granted the land of Mikulov (then called Nikolsburg) and the surrounding area to the
