Müller-Thurgau is a white grape variety (sp. Vitis vinifera) which was created by Hermann Müller from the Swiss Canton of Thurgau in 1882. It is a crossing of Riesling with Madeleine Royale. It is used to make white wine in Germany, Austria, Northern Italy, Hungary, England, Australia, the Czech Republic, Slovakia, Slovenia, New Zealand, the United States and Japan. There are around 42,000  hectares (104,000 acres) cultivated worldwide, which makes Müller-Thurgau the most widely planted of the so-called "new breeds" of grape varieties created since the late 19th century. Although plantings have decreased significantly since the 1980s, as of 2006 it was still Germany's second most planted variety at 14,000 hectares and 13.7% of the total vineyard surface. In 2007, the 125th anniversary was celebrated at the Geisenheim Grape Breeding Institute. Müller-Thurgau is also known as Rivaner (Austria, Germany, Luxembourg, and especially for dry wines), Riesling x Sylvaner, Riesling-Sylvaner (Switzerland), Johannisberg (Wallis canton in Switzerland), Rizvanec (Slovenia) and Rizlingszilváni (Hungary).
