Fortunato is an expert on wine tasting. He had a friend tell him he was an expert on it.
Montresor describes Fortunato as an expert in wines and a connoisseur. He plays off Fortunato's vanity by appealing to his knowledge of wines to lead him to his demise. Montresor also mentions that Fortunato's weakness is his pride and that he can easily be manipulated by flattery.
They are both connoisseurs of wines. Montresor states that while Fortunato is a quack when it comes to paintings and gemmary, he does know his wine. Montresor then says that he himself also knows his wines and is a frequent purchaser of many vintages.
Montresor appeals to fortunato's pride as a wine connoisseur
Montresor appeals to Fortunato's pride and vanity as a connoisseur of wines when he tells Fortunato that he has what might be a rare wine known as an Amontillado. He tells Fortunato that he will ask another person, Luchesi, to advise him if the wine is a genuine Amontillado. Fortunato's vanity makes him insist that he, rather than Luchesi, be the one to do the testing because he is a much better judge of wine than is Luchesi.
Both Fortunato and Montresor are depicted as prideful characters. They both show a sense of arrogance and self-importance in the story. Additionally, they both have a strong desire for revenge, leading to the main conflict in the narrative.
In "The Cask of Amontillado," Luchresi serves as a rival wine expert to Fortunato. Montresor mentions Luchresi to goad Fortunato into proving his own expertise in wine tasting, which ultimately leads to Fortunato's downfall. Luchresi never physically appears in the story but is mentioned as a means to manipulate Fortunato.
In 'The Cask of Amontillado,' Montresor provides numerous clues that had Fortunato been paying attention, might have seemed strange. First of all, he is continuously making references to Fortunato's health and the dangers of wet cold conditions. Obviously, this hints at the condition, Fortunato will soon find himself in. Next, when they discuss the Freemasons, Fortunato doubts Montresor is a member. He isn't even curious about why Montresor just happens to have a trowel on his person, which he reveals to prove his membership. When Montresor goes into a diatribe about his family coat of arms, Fortunato is either too drunk to pay heed.
Montresor lures Fortunado down by using his own weakness, wine. Fortunado is like an "expert" on wine, and MOntresor tells him to try this wine called "Amontillado". At first Fortunado declines, but then when Montresor tells him he'll get Luchesi instead he goes.
Fortunato prided himself on his knowledge of wines. As things turned out he should have had more of a knowledge of human nature. Perhaps he might have seen through Montresor and lived.
Montresor said he would get Luchresi's help if Fortunato wouldn't go with him. Fortunato is a fool when it comes to wine when he states in paragraph 14 that "Luchresi cannot tell Amontillado from Sherry." This is a clear indication that Fortunado is actually a drunkard and not a connoisseur of wine, for Amontillado is a Sherry wine. Luchresi is probably renowned in the wine business, so the threat of being outclassed motivates Fortunato to go with Montresor in arrogance.
There are only two characters: Montresor and Fortunato the only other people named in the story are Luchresi and Lady Fortunato, who takes no active part in the plot.
Montressor lured Fortunato into the tomb by challenging his pride and confidence in being a self proclaimed wine connoisseur. It was Fortunato's own cocky attitude (and drunkenness) that failed him. If Fortunato had been sober, he may have acknowledged the foreshadowing remarks made by Montressor during their journey.
