Blu 61 production follows artisanal blue cheesemaking methods, beginning with fresh, whole cow's milk from high-quality sources in Veneto. The milk is heated in traditional copper cauldrons and coagulated using natural calf rennet, creating a curd that is cut into pieces and drained to achieve the desired moisture content for a semi-soft cheese. The curd is then inoculated with Penicillium roqueforti or Penicillium glaucum cultures to encourage blue mold development. The curd is placed in molds and pressed, creating wheels that typically weigh 2-5 kilograms. The wheels are brined in salt solution for several days, then transferred to aging rooms where they mature for extended periods, typically 2-4 months, with some examples aged longer for increased complexity. During aging, the cheeses are regularly turned and monitored, with the rind developing a thin, pale exterior while the interior develops natural blue-green veining. The critical aspect of Blu 61 production is the development of blue-green veining, which occurs when Penicillium molds develop in the aging environment. The cool, humid conditions of the aging rooms, combined with the cheese's texture and composition, create ideal conditions for mold development. Some producers may pierce the cheeses with needles to encourage mold growth and air circulation. The molds break down proteins and fats, creating the distinctive tangy, sharp flavors and the characteristic blue-green veining that defines Blu 61. The extended aging allows for the development of complex flavors through enzymatic breakdown, with the cheeses developing nutty, savory, and tangy notes that reflect both the Veneto terroir and the natural blue mold development. Each wheel is tested by expert cheesemakers who evaluate quality through visual inspection, aroma, and texture. The finest examples showcase the unique character of artisanal blue cheesemaking, with balanced mold development creating complex, tangy flavors that make Blu 61 ideal for both table use and use in cooking.
Blu 61 is a distinctive addition to Veneto cheesemaking, offering artisanal blue cheese character that complements the region's traditional cheeses. It represents innovation in Italian cheesemaking while maintaining artisanal quality.
