“…The evaluation of the grape mechanical properties was used in recent years to study modifications in grape texture that may occur under different vine growing conditions (Sato, Yamada, Iwanami & Mitani, 2004;Rolle, Gerbi, Schneider, Spanna & Río Segade, 2011a;Giordano, Zecca, Belviso, Reinotti, Gerbi & Rolle, 2013;Zsófi;Villangó, Pálfi, Tóth & Bálo, 2014) and to monitor the grape ripening process (Maury, Madieta, Le Moigne, Mehinagic, Siret & Jourjon, 2009;Rolle et al, 2011b). Literature on the relationships among vineyard-related characteristics, such as bunch sunlight exposure and berry skin mechanical properties, is scarce.…”
