So every Gorgonzola and every Roquefort is a blue cheese, but a package marked only "blue cheese" is neither. The words Gorgonzola and Roquefort are legal names with rules about milk, place and age, and the plain term is not.

What blue cheese means
What blue cheese means is set out in the US federal standard: a cheese containing bluish-green mold throughout, at least 50 percent milkfat in the solids, no more than 46 percent moisture and at least 60 days old, according to 21 CFR 133.106. The standard names no country and no animal, so cow, sheep and goat blues all qualify.
The mold is Penicillium roqueforti, and it needs air. Makers pierce the wheel so the blue grows along the channels, which is why blues are crumbly or open in texture. The blue cheese guide covers the veins and the other famous blues such as Stilton and Danablu in depth. Because the category is so wide, a generic blue can be mild and creamy or sharp and salty, and the label rarely says which.
Gorgonzola: the Italian blue
Gorgonzola is the Italian blue, made only in a defined area of Lombardy and Piedmont from pasteurized whole cow's milk. It comes in two styles. Dolce is soft and mild enough to spread and is sold from 50 days of age, while piccante is firmer, crumblier and sharper and needs at least 80 days.
Most of what you find in the US is dolce. Gorgonzola is also one of the less salty blues: the consortium puts it at about 640 mg of sodium per 100 g, roughly 180 mg per ounce. The Gorgonzola page explains the foil label, the two styles and the American gorgonzola standard.
Roquefort: the French sheep's milk blue
Roquefort is the French blue, made only from raw whole sheep's milk and aged at least 90 days, beginning in the natural caves of Roquefort-sur-Soulzon. It carried the first appellation of origin for a French cheese in 1925 and became an EU PDO in 1996.
Sheep's milk is richer and more aromatic than cow's milk, and Roquefort is salted dry, so the result is moist, crumbly and bold. USDA lists generic Roquefort at 512.9 mg of sodium per ounce and 8.7 g of fat, against 324.9 mg and 8.1 g for generic blue cheese. Its mold is also different in lineage: a 2020 genomic study found Penicillium roqueforti was domesticated twice, with Roquefort using an older line. See the Roquefort page for the rules and for how to cook with it.
Which to buy: blue cheese, Gorgonzola or Roquefort
Which to buy among blue cheese, Gorgonzola and Roquefort depends on the dish and your tolerance for salt:
- Cream sauce, risotto, pizza: Gorgonzola dolce, which melts smoothly.
- Salad with pears and walnuts: Roquefort or Gorgonzola piccante, crumbled.
- A first blue: Gorgonzola dolce, the mildest of the named cheeses.
- Steak sauce: Roquefort melted into cream, tasted before any salt goes in.
- Dressing and wings: a generic crumbled blue, which costs less and does the job.
- A board: one named blue with honey or fruit, as the blue cheese pairing guide suggests.
What most blue cheese vs Gorgonzola vs Roquefort advice gets wrong
Most blue cheese vs Gorgonzola vs Roquefort advice makes three shortcuts: that all blues taste alike, that Gorgonzola is simply the mild one, and that Roquefort is just a French name for blue.
All blues are not alike. In a French study of cheeses made to Roquefort specifications, strains from the Roquefort mold population produced more of the compounds typical of blue cheese than strains from other populations, so the mold itself shapes flavor.
Gorgonzola is not always mild. Piccante is firmer and sharper, and the foil must say so. Dolce is the style that earned the mild reputation.
Roquefort is not a style. Only a cheese from raw sheep's milk, ripened in the Roquefort caves and meeting the PDO rules, can carry the name, and the US standard for Roquefort defines it as a sheep's milk blue. A cow's milk blue labeled Roquefort would be mislabeled.
