Cheese from Italy, the whole Autonomous Region of Valle d'Aosta
Valle d'Aosta Fromadzo PDOFromadzo
Fromadzo is the Aosta Valley's part-skimmed cow-milk cheese, eaten as an alternative to Fontina. Milk from at least two milkings rests for 12–36 hours so the cream can be taken off, then sets at 34–36 °C with natural rennet and the milk's own lactic bacteria. The curd is semi-cooked, pressed lightly in local moulds, salted over 20–30 days and ripened from two months to ten.

The resting time depends on the environmental conditions. The cream that rises is skimmed off, so the milk is partly skimmed by natural creaming.

At a glance
Fromadzo is the Aosta Valley's part-skimmed cow-milk cheese, eaten as an alternative to Fontina. Milk from at least two milkings rests for 12–36 hours so the cream can be taken off, then sets at 34–36 °C with natural rennet and the milk's own lactic bacteria. The curd is semi-cooked, pressed lightly in local moulds, salted over 20–30 days and ripened from two months to ten. Made in 7 steps over 2.6 months – 11 months. The longest step, ripen, takes 2–10 months (Disciplinare di produzione della denominazion…) and runs at 8–14 °C (Disciplinare di produzione della denominazion…). Lactococcus lactis, in a trial of two local starter mixes in Fromadzo; the better mix (AS2) reached mean frequencies of 87 % (valley-floor milk) and 70 % (alpine pasture milk) in 30-day cheeses does most of the fermenting.
Fontina uses whole milk, while Fromadzo uses milk from at least two milkings that rests until its cream can be taken off. It is lower in fat, cooked to at most 45 °C, salted slowly over weeks, and may be flavoured with herbs or a little goat milk.
Milk
Cow milk from at least two milkings, partly skimmed by resting; a little goat milk allowed
Ripening
At least 60 days, up to 8–10 months
Size
Cylinder 15–30 cm across, 5–20 cm high, 1–7 kg
Fat in dry matter
20–35 % for the semi-fat type; below 20 % for the low-fat type
FlavouredSeeds or parts of aromatic plants such as juniper or wild cumin added during making.
Mixed cow and goatA small share of goat milk added.
Safety
Fromadzo is made from raw milk, though the ONAF sheet also lists thermised milk. In a challenge study on Fontina, a raw-milk cheese from the same valley, E. coli O157:H7 added to the milk grew during the first hours of making and fell by about 3 log from its peak during 80 days of ripening; Fromadzo ripens at least 60 days. A fall of 3 log is not elimination. ANSES advises pregnant women, young children, people over 65 and people with weak immunity to avoid raw-milk cheeses other than cooked pressed ones such as Gruyère or Comté.
Hazards the sources name: Escherichia coli O157:H7, added to the milk in a challenge study on the sister cheese Fontina; it grew during the first hours of making and fell during ripening.
A tasting-guild sheet notes that the 15th-century Summa lacticiniorum of Pantaleone da Confienza describes a medium-sized, thick-rinded cheese of the Aosta Valley, and that 17th-century records name a fromage commun or fromage ordinaire made beside Fontina. In 1695, during the French occupation, the local council ordered alpine pastures to make butter and lean cheese instead of Fontina. It became a designation of origin in 1995 and an EU PDO in 1996.
