An examination of similar regional ratings in a 13-yr overlap period in these two indices (1988–2000) indicated moderate to strong correlation between the two (0.7 < r < 0.9). Overall, 30 categories of wine were represented in this analysis, covering 18–38 yr for the Sotheby’s ratings and 10–14 yr for the Wine Enthusiast’s ratings during the 1963– 2000 vintage year period (in some regions, Portugal and Champagne, vintages are often “undeclared” resulting in a discontinuous time series).
