The app user: “I don’t drink under 4.1”. The app user attaches great importance to a rating of 4.1 or higher before tasting a wine. His wine purchasing decisions are heavily influenced by his trustworthiness in expert opinion.

He relies on the application to help him choose high-quality wines and considers the reviews as a reliable guide for his selection.
