Suitability for cultivation and agronomic production

Müller-Thurgau is rather vigorous and is sensitive to chlorosis. It is preferable to plant this variety in sufficiently rich soil. Its very short cycle makes this variety well suited for northern or mountain areas, cold and limit from a climatic point of view. However, its resistance to winter cold is moderate.
Susceptibility to diseases and pests

Müller-Thurgau is sensitive to downy mildew and grey rot.
Technological potentiality

The bunches and berries are small or small to medium in size. Müller-Thurgau can produce aromatic, not very acidic and sometimes heavy wines with fairly high alcoholic degree and can sometimes lack finesse.
Clonal selection in France

The seven certified Müller-Thurgau clones carry the numbers 644, 645, 646, 647, 648, 649 and 650.
