Montresor tells Fortunato he has bought a special rare wine called amontillado but wants Fortunato to test it to be sure it is real . Fortunato goes with Montresor to the wine cellars of the latter 's palazzo , where they wander in the catacombs . Montresor offers wine ( first Medoc , then De Grave ) to Fortunato ; at one point , Fortunato makes an elaborate , grotesque gesture with an upraised wine bottle .
