One of the essential requirements for the production of Molinari Sempione ham is that the entire process takes place in a narrowly defined area, namely on the south side of the Simplon.
The wind blows through the alpine herbs as well as the larch and fir forests around the area where generally Molinari Sempione has its production. This creates a spicy and dry air that is ideal for the maturation of Molinari Sempione's products.
