Affinage is the French term for the process of bringing cheeses to their optimal degree of maturation. It's one of the important processes in cheese-making. The person whose profession or trade is "ripening" or "aging" cheeses is called
un affineur or
une affineuse. The time it takes to
affiner a cheese can vary widely, from a period of a few days or weeks to as long as several years. The methods and results vary depending on the characteristics of each variety of cheese.
Parmesan cheese (
Parmigiano Reggiano), for example, is ripened — dried, in this case — for at least 12 months and for as long as five years. The goat cheeses of the Loire Valley region are sold in several stages of ripeness:
frais (fresh),
demi-sec (medium hard), and
sec (hard, dried).
Cantal cheeses, one of France's first and oldest cow's milk cheeses — the Romans discovered it when they conquered Gaul 2,000 years ago — are ripened to several different stages before being marketed: you can get
cantal jeune (young, ripened for 30 to 60 days),
cantal vieux (aged for at least 240 days), or
cantal entre-deux (medium, "between the two" other styles, ripened for 90 to 210 days).
For cheddar cheese, which was supposedly developed in England after Romans took the
cantal cheese-making method there, those stages of ripening are called mild, sharp, and extra-sharp in North America. In the U.K., the corresponding terms seem to be mild, medium, mature, and extra-mature.
This is a long post about cheese-ripening because Walt and I use a lot of Parmesan cheese in our cooking, but we would also like to use the cheese called Pecorino Romano, which we don't have a good source for here. I'm sure you can find it in Paris and other big cities, but not out here in the countryside.
Pecorino Romano is a cheese made from ewe's milk. The ewe, if you don't know, is the female sheep, as the cow is the female bovine. So in Italy and Europe, Romano cheese has to be made from sheep's milk. It is aged and grated like Parmesan, but with a different taste of course. (On the left,
pasta with pesto and my ripened and grated sheep's milk cheese.)
Well, in the U.S. it's not so simple. American Romano cheese can be made from sheep's milk, cow's milk, or goat's milk. It's an industrial product.
We can easily find ewe's milk cheeses here in our Saint-Aignan supermarkets. It dawned on me a couple of months ago that I might be able to "ripen" a soft, mild piece of ewe's milk cheese until it really dried and hardened enough to be grated like Parmesan cheese. The ewe's milk cheese we get is mostly made in Basque country and the Pyrenees Mountains in southwestern France.
The ewe is called la
brebis in French, and the cheese is called
fromage au lait de brebis. One commercial cheese is called
Etorki, and it's aged for 50 days before being sent to market. Another is
Ossau-iraty, a farmstead AOC/AOP ewe's milk cheese that is ripened for 80 to 120 days, depending on the size and weight of the cheese being ripened. Other famous ewe's milk cheeses are Roquefort and traditional Greek feta...
My
affinage experiment worked. I can't remember which ewe's milk cheese I bought — it might well have been a piece of Etorki. I cut a thick slice of it and just wrapped it in a paper towel and put it in the refrigerator. Then I basically forgot it for a couple of months. It could "breathe" through the paper towel, and refrigerators are notorious for drying foods out. At the end of this fridge-based
affinage, the chunk of cheese had really dried and hardened. It didn't go moldy. As you can see, it grated the way Parmesan does, and take my word for it, it tasted good in pesto on pasta.
