During the next phase, each Coppa is packed into sewn pork pleurae and treated with vinegar, which helps the casing to keep the Coppa soft. Pork pleurae are odourless and flavourless, unlike intestines, widely used in this sector for casings. We also decided not to use synthetic membranes as we believe that tradition and quality also depend on these small details. After having bound each piece with the aid of machinery, our operators stitch them again by hand, using twine with care and experience.
