摘要:Grape quality is regulated by complex interactions between environments and cultivars. Growing suitable cultivars in a given region is essential for maintaining viticulture sustainability, particularly in the face of climate change . We created a database composed of three diferent subsets of data . The frst subset was created by digitizing and curating the seminal report of Amerine and Winkler (1944), which provided grape harvest dates (GHDs), the quality of musts and wines, and wine tasting notes for 148 cultivars from 1935–1941 across fve contrasting climatic regions of California . To put this dataset into a climate change context, we collected GHDs and must sugar content (°Brix) records from 1991 to 2018 for four representative cultivars in one of the fve studied regions (Napa) . Finally, we integrated meteorological data of the fve regions during 1911–2018 and calculated bioclimatic indices important for grape. The resulting database is unique and valuable for assessing the ftness between cultivars across environments in order to mitigate the efects of climate change .
