Every year, SOWINE unveils a comparative assessment of the performance of wine, champagne and spirits brands and estates across social media. Sowine Digital Index rankings are published region by region. Bordeaux and Champagne are the top two appellations on this annual ranking. As the first objective and in-depth study analysing the performance of brands and estates on social media, the Sowine Digital Index tracks the top 100 brands and estates in each region across various social media platforms.
