Supplemental Data
Supplemental Table 1 Area, cultivar similarity index (CSI) relative to the world, cultivar concentration
index (CCI) for each country in 2000 and 2016, and cluster classification based on
both CSIs relative to the world and CCIs in 2016.
Supplemental Table 2 Cultivar Similarity Indexes (CSIs) between countries, and between countries and the world as a whole, in 2016.
Supplemental Table 3 Cultivar Similarity Indexes (CSIs) between countries, and between countries and
the world as a whole, in 2000.
Supplemental Figure 1 Dendrogram based on winegrape cultivar similarity indices (CSIs), 2016. Dissimilarity
= 1 - CSI. The clustering method is average linkage. The dashed vertical line shows
a nine-cluster classification based on CSIs between countries.
Supplemental Data Concentrations and similarities across countries in the mix of winegrape cultivars.
