From 1882, the phylloxera epidemic hit Hungary hard, with the traditional field blends of Eger and the many grapes of Tokaj being replaced with monocultures, often of Blaufränkisch (Kékfrankos) and the Bordeaux varieties in red wine districts, and of Furmint, Muscat and Hárslevelű in Tokaj. The twentieth century saw the introduction of modern grapes such as Zweigelt, which were easier to grow and to vinify than Kadarka. Under Communism quality was neglected in favour of overcropping, pasteurisation, and industrial production. Since 1989, there has been renewed interest in the traditional varieties and much new investment, particularly in Tokaj-Hegyalja.
