At the beginning of the story, Fortunato insults Montresor by questioning his knowledge of wine and expressing doubt in his ability to accurately judge the quality of Amontillado. Fortunato belittles Montresor by stating that he doesn't believe Montresor is a true connoisseur of wine and that he is probably not capable of distinguishing between different types of wine. This insults Montresor's pride and expertise in wine, leading him to seek revenge against Fortunato.
