Bud burst: 10 days after Chasselas.Grape maturity: period II, 2 weeks to 2 and 1/2 weeks after Chasselas.
Suitability for cultivation and agronomic production
Sauvignon gris G is less productive than Sauvignon B.
Sensitivity to diseases and pests
The behaviour of this variety would appear to be the same as Sauvignon B.
Technological potential
The grape clusters and berries are small. Sauvignon gris G can produce very powful wine, full-bodied with slightly heavy aromas and lower acidity than Sauvignon B. Sugar accumulation potential is very high (higher than for Sauvignon B) and is particularly well adapted for the production of liqueur wines.

The only approved Sauvignon gris G clone carries the number 917. A conservatory with over 50 clones was set up in Anjou in 2000.
