Suitability for cultivation and agronomic production
Pineau d’Aunis is a moderately vigorous variety, very susceptible to browning and fertile when pruned short. Its production sometimes tends to be irregular (alternates). Pineau d'Aunis is also sometimes susceptible to chlorosis.
Susceptibility to diseases and pests
As its grape clusters are compact, this variety is susceptible to grey rot. It is however not very sentive to phomopsis.
Technological potentiality
The bunches are medium in size and the berries are small. Pineau d’Aunis makes light and not very colored wines for the production of rosé wines or base wines for sparkling wines. The quality drops quickly when the yields increase.
Clonal selection in France
The two certified Pineau d’Aunis clones carry the numbers 235 and 289. A conservatory of 150 clones was planted in Vendomois (French department of Loir et Cher) in 1997.
