Twelve Caciocavallo cheeses were collected from 6 factories (A, B, C, D, E, F) located in the Monti Dauni Meridionali area (Southern Italy) that adopted different protocols for cheese production. A total of 160 consumers were involved in the sensory evaluation of Caciocavallo cheese after 180 d of ripening. Cheese attributes were used to describe the flavor, texture, and appearance of cheeses. The highest scores for the shiny attribute were assigned to cheeses B, C, and E, whereas color intensity was the highest in cheeses B, D, and F. Strength, salty, and piquant attributes were higher in cheeses F and A because of the use of raw milk (F), rennet paste (A), and percentage of salt in the brine (A, F). Consumers perceived a more granular structure during the second half of chewing of Caciocavallo cheese F, as evidenced by the highest value for the grainy attribute. A positive correlation was found between overall flavor and odor intensity and water-soluble nitrogen, low molecular weight peptides, and free fatty acids and between piquant and butyric and caproic acids. A principal components analysis applied to the sensory attributes accounted for 65% of the total variance. The score plot showed that cheeses F and A were located in a well-defined zone of the plot, with cheeses in this zone displaying higher levels of strength, piquant, and salty attributes. The preference test assigned 40% of the preference to Caciocavallo cheese A, 38% to cheese F, 9% to cheese E, 8% to cheese D, and 7% to cheeses B and C. Sensory evaluation of Monti Dauni Meridionali Caciocavallo cheeses is a useful analysis to highlight the principal attributes able to influence consumers' liking that are related to biochemical features of the cheese.
