The microbiological and chemical parameters of a mountain raw milk che
ese are considered. The ''Quartirolo di Monte'' is a cheese made from
the unpasteurized milk of cows that in summer graze on mountain pastur
es and in winter are fed dry feed. The quality of the product is influ
enced by the collection of the milk, the variations in its composition
and the different technological conditions. We suggest an adequate re
frigeration of the bulk milk and the use of natural starter cultures t
o maintain, but not alter in any way, the characteristics intrinsic to
the typicalness of that cheese.
