Crowdsourced the assessment of wine rating: professional wine competition rating vs vivino rating
Abstract
We evaluate wine ratings by comparing data from two crowdsourcing platforms – Vivino, which aggregates the opinions of a large number of wine lovers, and Global Wine Medal Rating, which aggregates the scores from more than 1030 international wine competitions since 2020. The study analyzes the ratings of over 120,000 wines that have participated in professional wine competitions since 2020 and which, collectively, have received over 439,000 medals during that time. The aggregated results of the wines’ participation in wine competitions were compared with the scores of these wines in the Vivino rankings. Possible reasons for significant discrepancies in the scores of wines in wine competitions and Vivino were analyzed when such discrepancies occur. Overall, our results demonstrate that crowdsourced ratings are a reliable source of information for both consumers and producers. But the ability to easily compare ratings from different crowdfunding platforms, which form ratings according to different criteria, makes it much easier for the end consumer to choose a wine depending on their preferences for the type of rating or to find wines that have comparably high scores in different crowdsourced ratings.
