Plant thermal adaptation to CC was determined in each study area using the Amerine and Winkler index. This was calculeted as following, and compared with the Aglianico and Cabernet Souvignon thermal requirements for all sites and climate scenarios.

Amerine & Winkler formula

GDD= ∑((Tmax+Tmin))/2-10))

From 1 April to 31 October

The thermal requirements applied were 2110 and 1950 GDD for Aglianico and Cabernet Sauvignon respectively
