Knowing that Fortunato considered himself a great expert, or connoisseur, of fine wines, and especially a devotee of a sherry known as Amontillado, Montresor flattered him by obsequiously asking his opinion on a newly acquired cask of Amontillado. He tantalized Fortunato with the rare liquor, even pretending that his vaults where the wine was stored had too much dampness and "nitre" for Fortunato's afffiction. However, Fortunato was determined to taste the wine and insisted on being taken to Montresor's home. Montresor complied while wrapping himself in a cloak to make sure that he would not be recognized. Earlier, he had let all of the servants off for the night, using the excuse of the carnival; in this way he would avoid arousing Fortunato's suspicions and would also prevent anyone from witnessing the atrocity he planned to commit. Apparently, Montresor had been planning this revenge for a long time and, ironically, had chosen carnival time as the setting for this most horrible type of crime. Amid the gaiety of the carnival, he was sure he would avoid any possibility of being detected.
As they descended into the vaults, Fortunato walked unsteadily and the "bells upon his cap jingled" as they descended, creating a further carnival atmosphere or a joyous time, a time which will ironically end soon with the living death of the unfortunate Fortunato.
As they passed deeper into the vaults, the nitre caused Fortunato to cough constantly, but he was drunkenly determined to continue. At one point, however, Montresor paused and offered Fortunato a bottle of Medoc wine to help ward off the cold and the fumes of the nitre. This seemingly kind act, of course, carries undertones of the most vicious irony, since what appears to be an act of kindness is only an act performed to keep the victim alive long enough to get him to the niche where he will be buried alive.
