White wine grape variety
Parentage
This grape variety was bred in 1882 in Geisenheim by the Swiss botanist Hermann Müller, from the canton of Thurgau. For a long time, it was believed that Riesling and Sylvaner were the parent varieties, until genetic research finally proved otherwise. Müller-Thurgau is the oldest and most successful new cultivar to have spread throughout the world. The synonyms Rivaner and Riesling-Sylvaner point to the variety’s original (yet incorrect) attribution of parentage. Use of the name Riesling-Sylvaner is now prohibited, due to it being misleading.
Vineyard area
This variety grows in all of Austria’s wine-growing regions. Between 1999 and 2020, however the area under vine declined considerably, as did the variety’s significance.

Significance & conditions
This variety ripens very early and is therefore often sold as grape must, Sturm (partially fermented grape must) and en primeur wine (wine still maturing in the barrel). Müller-Thurgau is often blended with other white wine varieties to produce young cuvées that are intended to be drunk straight away. At the other end of the maturation spectrum, this variety also produces Prädikatswein whose potential for developing is often underestimated. Müller-Thurgau needs soils that offer deep root depth and a good supply of water. It is very susceptible to Peronospora, oidium, berry and stem rot, Pseudopezicula tracheiphila and Phomopsis. Compared to other varieties, Müller-Thurgau needs increased protection.

(as a proportion of the variety’s total area)

Total area in Austria:
The Leithaberg and Neusiedlersee wine-growing regions overlap by almost 160 ha (Rieds Hausberg and Neuberg), according to the Austrian Wine Law. This means that the listed area under vine in Burgenland is 160 ha less than the actual total area across all wine-growing regions in Burgenland.
Characteristics of the wine
The variety creates early-maturing, mild wines with a faint muscat flavour. If acidity is too low, the wines age quickly. Prädikatswein can achieve a very high quality potential.
