All French cheese (and foods, for that matter) have an "M.G." notice on the label. That is not the mg (milligram) marker, but rather "Matières Grasses" ("Fat Matter", literally). Many of the delicious cheese I love are, obviously, very high in fat. Most aged or pressed cheeses are around a quarter to just under a half (25%-45%) fat by weight. Just look on the label for the "M.G." indicator, sometimes also written "M,G" or (incorrectly and confusingly) "mg" or "Taux de M.G." which means "rate of M.G."
