Mueller Thurgau

the white Rebsorte Mueller Thurgau, today for marketing reasons also Rivaner mentioned, became 1882 of the Swiss of Rebfor Professor. Hermann Mueller (* 1850; † 1927) at the research institute Geisenheim in Rhine gau bred. Mueller Thurgau is with 42.000 hectars cultivated areaworld-wide the most successful new breeding.

The sort places relatively small requirements at climate and ground condition. The vines mature early and bring large yield quantities. The sort Mueller Thurgau is mild due to their small acid, but elegant and fruchtig. The wines are stillto be relatively young drunk, with few exceptions they become not better by the storage.

Drying and half drying developed the sort is called today very frequently “Rivaner”, after the originally assumed parents vines Riesling and Silvaner. The reason: Although itselffrom Mueller Thurgau quite hochklassige wines keltern leave, have the grape/cluster meanwhile at the public very a bad reputation, because them were all too often abused due to the attainable high yield for inferior mass wines.

Crossing partner

Mueller was however not completely safe itself, who parents Rebsorten was actually used by it. Therefore there was doubt also from the outset. Attempts to reconstruct breeding failed. Long time assumed one it itself around oneCrossing from Riesling with itself acts.

1998 could be excluded in the monastery new citizens viticulture school in Austria with the help of towards-diagnostic procedures (use of specific micro satellites) Silvaner as crossing partners. The result suggested Chasselas as crossing partner (father candidate). Scientist of the GermansFederal Institution for breeding research in Siebeldingen/Pfalz could some years ago with new, extended towards-diagnostic possibilities the origin of the Mueller Thurgau vine still more exactly determine: They defined the Rebsorte larva line Royal as a father. Larva line Royal is a breeding from the form circle of the Chasselas (property noble).

The cultivated area in Germany amounted to in March 2004 17,280 hectars, corresponds to 16.8% the Rebfläche.

1933

the white Rebsorte Bacchus developed for descendants by further crossing of a seedling (Silvaner x Riesling) with Mueller Thurgau. Mueller Thurgau was likewisetaken part in the following further new breeding:Cantaro, Faber, Fontanara, Gloria, Goldriesling, Gutenborner, chancellor, Muscabona, optima, Ortega, bead, regent, Reichensteiner, beautiful tl grape/cluster, September timer, Tamara and Thurling.

Ampelografi description

In the Ampelographie the Habitus is described as follows: Sheet medium sized, five to siebenlappig, deeply gebuchtet, strongly curved; Blade upper surface weakly blasig, bald; Lower surface spinnwebig, bald-end; Handle bay overlapping; Page margin sawed off. Sprout lightgreen, easily flaumig with reddish approach. Grapes/clusters means to large, looseto dichtbeerig, conical, often training ore. Berry medium sized, oval, yellowish-green, easily beduftet; Berry meat juicy with clear Muskatbukett.

characteristics

the vine and prefers deep, freshness is starkwüchsig, not to dry soils. It has small requirements to the location, is but sensitively to drynesses. Those wood-develops can weakly be, thus frequently already with -15 °C frost damages. A high susceptibility against Peronospora, Phomopsis, red burner and Botrytis cinerea is given. The kind of educating is to be selected in such a way that a goodAeration of the leaves wall is possible. The Rebsorte has a large bloom firmness after May frosts, by fruitful Beiaugen, usually comes it only to small Ertragsausfall. Matures starting from in the middle of September. A Mostgewicht of 65-90° Oechsle can be obtained with with 100-150 hl/ha, inare possible for some years also over 200 hl/ha.

Mueller Thurgau wine

the Moste predominantly developed to süffigen, light, elegant quality wines with pleasant Muskatton and moderate acid. Depending upon location they are more or less blumig. In some yearsmust be counted on small acid. As carousing wine, freshly drunk, he is most beautiful. Storage times of 2 to 3 years should not be exceeded, since otherwise the fine Muskataroma is lost.
