Economics of Winegrape Adaptation: Technology Adoption, Cultivar Selection, or Migration

Supplemental Figure 1  Number of days per year above 35°C in Napa County (Napa State Hospital).

Supplemental Figure 2   Napa County extreme heat days and Cabernet Sauvignon yields. Grape crush values were calculated using the total crushed quantity from the USDA California Grape Crush Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Crush/Reports/) and the total land area from the USDA California Grape Acreage Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Acreage/). The red line in the graph shows the estimated trend across observations.

Supplemental Figure 3   Napa County extreme heat days and Carignane yields. Grape crush values were calculated using the total crushed quantity from the USDA California Grape Crush Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Crush/Reports/) and the total land area from the USDA California Grape Acreage Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Acreage/). The red line in the graph shows the estimated trend across observations.

Supplemental Figure 4   Lake County extreme heat days and Cabernet Sauvignon yields (Lyons Valley). Grape crush values were calculated using the total crushed quantity from the USDA California Grape Crush Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Crush/Reports/) and the total land area from the USDA California Grape Acreage Reports (https://www.nass.usda.gov/Statistics_by_State/California/Publications/Specialty_and_Other_Releases/Grapes/Acreage/). The red line in the graph shows the estimated trend across observations.
