There are two names for this wonderful grape variety, one from the French (gris) and one from the Italian (grigio)
What to call the wine is the question in the new world. In Australia there seems to be a trend to calling the wine by its style. Gris for fuller bodied wines and grigio for the more austere and 'Italian' style.
The Australian Alternative Varieties Wine Show which has done much to promote PG, and other varieties, divides its PG class into subgroups Dry Crisp and Crunchy" and "Rich and Full Bodied" to better compare like with like.
By the way the number of producers of wine from this variety is now approaching 300, more than 10% of australian wineries. See
