Medlar (Mespilus germanica L.) is a minor fruit tree sometimes cultivated since the antiquity in Europe and presently almost forgotten. In Italy, the medlar has been proposed in last years for fruit production diversification and their pomes are presently more widely available in specialized grocery shops and in niche markets. Sensory analysis is a good tool to obtain a deep knowledge of old germplasm quality, inte-grating the conventional characterization and evaluation work. The trial was aimed at the definition of sensory differences among the medlar cultivars Comune, Gigante di Castel-raniero, Goccia and Precoce, collected at the experimental farm of Università della Tuscia, in Viterbo, to evaluate their fruit quality and their potential for a commercial exploitation. At the beginning of November anonimous samples of bletted flesh were submitted to eleven panelists previously trained for a better knowledge of the meaning of the chosen attributes. The following characteristics were considered: smell intensity, fermented, alcoholic; flesh sweetness, acidity, adstringency, flavour, firmness, juiceless, fibrousity, grittiness; the level of global appreciation of taste and smell was also expressed. To avoid any influence on the evaluation of flesh sensory attributes, only at the end of the tasting session, the external fruit aspect at ripening and bletting was evaluated by the panelists. A sensory score sheet with a 11 cm unstructured line scale was used for descriptive terms. Sensory analysis on bletted flesh revealed a good appreciation of Goccia and a negative judgement on Gigante di Castelraniero. Comune was the most appreciated cultivar for the external fruit aspect. Sensory profile showed big differences among cultivars. Gigante was perceived as characterized by scarcely sweet, dry and fibrous flesh; Goccia was considered sweet, with low acidity and with absence of fibrousity. Goccia and Comune were the culti-vars more appreciated for the taste. Goccia received the highest score for aroma.
