Phenology
Bud burst: 2 days after Chasselas.
Grape maturity: period I, 1 and 1/2 weeks after Chasselas.
Suitability for cultivation and agronomic production
Pinot gris G is rather vigorous but not very productive. This variety is well adapted to northern regions, rather deep limestone, relatively dry and well exposed  terroirs. It is not very sensitive to winter cold and its fruit production is good following spring frost.
Sensitivity to diseases and pests
This variety is a little sensitive to grey rot and downy mildew.
Technological potential
Grape clusters and berries are small or very small in size. Pinot gris G can produce wines of great finesse: very powerful, full-bodied and aromatic. Sugar accumulation potential is high and acidity low to moderate. Wines made from Pinot gris G are generally a pronounced yellow color and have specific aromas compared to Pinot blanc B.
Clonal selection in France
There are 3 approved Pinot gris G clones which carry the numbers 52, 53 and 457. A conservatory collection including  200 or so clones and was set up in Alsace in 1984.
