Suitability for cultivation and agronomic production
Semillon has moderate vigor and is rather productive. This variety can be pruned moderately long or short. It reacts particularly to the agronomic fertility of the soil. The yields vary enormously depending on the terroirs. Semillon seems well adapted to gravelly or clay-limestone soils.
Susceptibility to diseases and pests
Semillon is sensitive to grey rot, black rot (on young leaves), to mites and vine leafhoppers. On the other hand, it is not very susceptible to powdery mildew and eutypa dieback.
Technological potentiality
The bunches are medium and the berries are large in size. Semillon, under favorable growing conditions, with adult vines and managed yields, produces full-bodied great quality dry white wines, with moderate to low acidity. These wines can be vinified in barrels and are suitable for ageing. Semillon also produces great white liqueur wines.
Clonal selection in France
The seven certified Semillon clones carry the numbers 173, 299, 315, 380, 908, 909 and 910. Two conservatories of more than 130 clones in total have been planted in the Bordeaux wine-growing region in 1997 and 2011.
