The aptitudes are close to those of other types of Grenache, but this variety would appear to be a little more productive than Grenache blanc.
Sensitivity to diseases and pests
The susceptibilities and tolerances and Grenache gris seem identical to those of Grenache blanc, but with a greater sensitivity to grey rot.
Technological potential
The bunches and berries are small to medium in size. Grenache gris is especially used to produce sweet wines and grey wines, "vins gris" (in the sands of the Mediterranean coast).
