Origin
This cultivar is a mutation of white Grenache.
Description
The description matches that of Grenache noir, except for
the berry colour which is yellow-green at full ripeness
Phenology
Time of bud burst: early, a few days before Grenache noir.
Time of maturity: mid season, slightly earlier than Grenache
noir.
Production
This cultivar seems to be less susceptible to rain damage than
Grenache noir and proves to be a little earlier. It is resistant to wind, has
an upright habit and is well suited to drought conditions (gravel or stony soils).
Grenache blanc, like other types of Grenache, is sensitive of magnesium
deficiency.
Susceptibility to
diseases and pests
Grenache Blanc is very sensitive to botrytis, phomopsis, downy
mildew and bacterial diseases. It is rather resistant to powdery mildew, leaf
hoppers and mites.
Type of wine/Flavours
Clusters are large while the berries are medium. Grenache
Blanc are used for the preparation of fortified wines but also allows to obtain
interesting dry white wines with a long finish, full bodied but sometimes lacks
a little acidity.
