The seventeenth century, and even more so the eighteenth century, saw intense developments in livestock farming. In addition to the permanent residents of Bergamo many people were involved in seasonal migration. Originally form the valley, seasonal migrants would leave the valley to go down to the plain with their livestock in the winter months, returning for the summer season to the high pastures where, as Giuseppe Locatelli (author of “Cenni ed Osservazioni sulla Vallata di Taleggio”, a handwritten document from 1823) clearly tells us, they produced a consistent and diversified production of dairy products, including Stracchino, Formaggella, butter, mascherpe cheese and, above all, mountain cheeses. Dairy farmers invested heavily in the Stracchino cheese during the brief period of time between the descent from the mountain pastures and when they left the plains. Those who remained permanently with their animals in the village also produced cheese during the winter; before being sold, they were seasoned to improve the taste of the resulting dairy products.
