Predicting Italian Wines Quality from Weather Data and Experts’ Ratings
نویسنده
چکیده
In this paper we examine how the weather determines the quality of wines produced in the Barolo and Barbaresco regions of Italy. Since pricing data are not widely available for these wines, we measure wine vintage quality by a variety of subjective measures of quality taken from the published opinions of several experts. Since these measures of quality are only ordinal, we estimate their determinants using an ordered probit function that incorporates multiple indicators of quality and a common underlying structure of how the weather determines quality. The method provides measures of the determinants of vintage quality ratings and suggestions on the reliability of each expert.
