There is no cask of Amontillado in the catacombs. Montresor invented it in order to lure Fortunato down there, where he could chain him to the rock wall and leave him to die. It is important to understand that Fortunato is not anxious to drink the wine; that is not why he goes to so much trouble to get to it, in spite of his bad cold, and in spite of being inadequately clothed in a jester's costume. Nor is he anxious to show off his connoisseurship in wine. He is thinking of buying some of the Amontillado for himself--and Montresor knows that is what he is thinking. Both of them deal in luxury items, including art works, "gemmary," and fine wines. But Fortunato has to taste the Amontillado--just taste it--before he can feel safe about buying some of it himself. Since he is a rich man, he can afford to buy a whole shipload of the wine and resell it at a profit. Since he and Montresor are competitors, he has probably beaten the other man out of profitable deals in the past. These would be some of the "thousand injuries" Montresor mentions as the cause for his desire for revenge. He can never taste the Amontillado because it does not exist/

Sadly for Fortunato, the antagonist in Edgar Allan Poe's short story, "The Cask of Amontillado," the Spanish sherry promised by Montresor was only a ruse to lure him deeper into the catacombs. There apparently was no bottle of the rare vintage for Fortunato to sample, and it was never produced. The two did share several other bottles: One was a Medoc, a red wine from the Bordeaux region of France; and the second was a De Grave, from the Graves district. Poe probably chose the De Grave as an ironic twist, since after drinking it, Fortunato was led to "the grave."
