  text: '<jats:title>Abstract</jats:title><jats:p>Changes in winery ratings in leading
    wine guides, that is, improvements as well as deteriorations, are typically attributed
    to corresponding changes in the quality of the wines produced by the respective
    winery. What remains unexplored in this context is changes in editorship and/or
    changes in the composition of the wine tasting teams working for the respective
    guide. Using data from two particularly prestigious German wine guides (Gault
    Millau and Vinum), this paper shows that these latter changes have a rather small,
    yet statistically significant impact on changes in winery ratings. Thus, consumers
    are well-advised to consider these changes before making their purchasing decision.
