The company Paltrinieri Renato s.r.l. was founded in 1948 to the delight of those who love gorgonzola.

Now Sergio and Roberto Poletti, managers of the company located in Cavallirio, continue to be appreciated both for the passion and care that they devote to qualitative research which supports the most advanced technologies, manual processes are firmly secured to the oldest and most authentic dairying traditions, that to the attention to the environment, thanks to an advanced photovoltaic system from 100 Kw, the authentic flagship of the company. Paltrinieri Renato offers gorgonzola “Palzola,” sweet style, white and creamy, to spicy, which taste definitely more intense and refined making it a true cult for connoisseurs. The offer is completed with the new one called “Palfuoco” that is a tasty cheese, with cream and spicy hints awarded by a clever addition of chili.

Gorgonzola is a very ancient cheese. Some say Gorgonzola was first produced in the town of Gorgonzola, near Milan, in the year 879 AD. Some other say that it was first produced in Pasturo nella Valsassina, a great cheese-making area for centuries, due to the presence of excellent natural caves where the average temperature is constantly between 6°C and 12°C. Therefore, this allows perfect making of Gorgonzola as well as several other cheeses.

In any case, the town of Gorgonzola remained the most famous place, although it was not the main production or trade centre for various centuries. In fact, the real Gorgonzola’s first name was “stracchino di Gorgonzola”, later better defined with the synonym “green stracchino”. In this context, this cheese was certainly produced with autumn milking when cows returned from mountain pastures.

Gorgonzola constantly spread in both Lombardy and Piedmont regions, though slowly if compared with other cheeses: Pavia and Novara joined Milan and Como areas in the production of Gorgonzola.

The area to be defined by the 1955 and 1977 Decrees was thus already operating as a production and maturing area of Gorgonzola cheese, whose designation was protected at that point.

Since the beginning of the 20th Century, the success of Gorgonzola cheese has been growing – especially abroad – with an export record of more than ten thousand tons per year to the UK, France, and Germany. British consumers prefer white, soft, slightly spicy Gorgonzola, whereas the French and Germans specifically order blue-veined, strong Gorgonzola, the so-called “two-curds cheese”.

Immediately after the Second World War, a new technique was implemented: “one-curd” processing. This new production system replaced the previous, empirical procedures, which were significantly more expensive as well as more hygienically and qualitatively inconsistent. Cheese factories and the many creameries spread all over the Po River Valley collect milk from farms and produce cheese, which is then transferred to the main maturing units. During the 1970s, the more than 100 cheese factories had to modernize their production plants and various small production units had to fold up, as they could not bear the costs. At present, approximately thirty well-structured large and medium-size companies process milk and mature gorgonzola cheese in their modern plants.
