According to Montresor, what kind of person is Fortunato?

Montresor wants revenge on Fortunato, so we must understand that we are getting a biassed view of Fortunato. Montresor says he has put up with a "thousand injuries" from Fortunato, though he doesn't specify what they are. He says too that Fortunato has "insulted" him, though he doesn't say how. 

Fortunato, Montresor continues, is a man to be respected and feared but has a "weak point," which is his pride in his knowledge of wines. Fortunato obviously thinks he knows far more about wines than his rival, a man named Luchresi, and Montresor plays heavily on Fortunato's jealousy of that rival to get him to enter the dank catacombs. 

Through Montresor's eyes, we see Fortunato as a figure respected by the rest of the world, but also as a drunken fool, easily baited and flattered, who Montresor plays expertly and gets the best of, luring him to his death.
