Suitability for cultivation and agronomic production

This variety is fertile, productive and must be pruned short-pruned. It is adapted to clay-limestone terroirs and sandy terrains (it was used to be grown ungrafted in the sands of the Mediterranean coast). As maturity is reached fairly late, it must be planted in warm southern regions. Grafting this variety onto 110 R should be avoided.
Susceptibility to diseases and pests

Piquepoul blanc is sensitive to grey rot.
Technological potentiality

The bunches are large and the berries are medium in size. In appropriate terroirs, Piquepoul blanc produces typical, lively and pleasant white wines.
Clonal selection in France

The four certified Piquepoul blanc clones carry the numbers 176, 237, 238 and 463. A conservatory of almost 400 clones was planted in 1994 in the French department of Hérault.
