Parmigiano-Reggiano (a globally beloved type of Parmesan cheese) is only made in five select provinces in the Emilia-Romagna and Lombardy regions, and its production is protected under strict protective regulations that have not changed in centuries. Visiting the Consorzio del Formaggio at BIO Reggiani Dairy allows you to get a closer look at the production and aging process, which takes at least 1 year. Admire the milk simmering in giant copper cauldrons, the cutting of the curds, and the aging rooms where massive wheels rest on wooden shelves. Typical viewing hours are from 8:00-12:30 and 15:00-19:00 Monday to Saturday, with only the morning slot open on Sundays. Visit early in the morning to see the full production process, and book a tour and tasting in advance: https://www.parmigianoreggiano.com/dairies-book-a-guided-tour/product_id=291682
