Aromes au Gene de Marc is a small, soft French cheese from the Lyon area that is coated in grape marc, the skins, seeds and stalks left after the juice is pressed. It is made from cow's milk, sometimes goat's milk, and the milk is raw in most descriptions, so the label of your piece is where to confirm the milk treatment.

The same cheese also goes by arôme de Lyon, arôme de gêne de marc, arôme lyonnais and arôme au vin blanc, and the name is an unprotected appellation.

What Is Aromes au Gene de Marc Made From?

It starts as an immature cheese such as Rigotte or St Marcellin, and Picodon and Pélardon are also among the cheeses that go through the marc treatment.

That base is a lactic-curd cheese, whose curds are ladled into moulds, lightly pressed, drained, salted, dried and then aged.

The pieces sold by Les Alpages, a Saint-Marcellin, and by Fromagerie du Château are both raw cow's milk.

How Is It Made in Grape Marc?

The young cheeses are macerated or cured in fermenting grape skins and pips, then rolled in marc before they are sold. That marc coating gives the finished cheese its rind and its aromas.

Wine plays a part in some versions: in a white-wine step the cheeses sit on small racks in jars so they take up the wine vapour, and they are also macerated in white wine or in grape stalks sprinkled with red wine.

The Saint-Marcellin that Les Alpages sells is steamed with white wine and then aged in barrels of grape marc. Fromagerie du Château's piece is aged 3 weeks with white wine (under 1% of the ingredients) and grape must, so its label names must rather than marc.

The time in the marc runs from 3 weeks to 2 months depending on who describes it, so ask the seller how long your piece was aged.

The method is traced to storing unsold summer cheeses, where the lack of oxygen and the alcoholic juice protected them against bacterial growth.

When it is made differs by account: Wikipédia says it is made all year and sells far more in winter, while Cheese.com says it is produced several months after the last of the vintage.

What Does It Taste Like?

Aromes au Gene de Marc is described as strong and fermented. Cheese.com calls it strong, bittersweet and distinctly yeasty with a fermented, pungent aroma, and Androuet gives it a pungent flavour and a strong smell of fermenting must.

Wine shows up in some descriptions: OPT describes slightly vinous notes from the marc, and Fromagerie du Château calls its piece fruity and slightly vinous.

By Cheese.com's account the texture changes as it matures, from creamy and moist when young to flaky and hard when aged, so ask for a young piece if you want it creamy.

How Do You Serve Aromes au Gene de Marc?

Aromes au Gene de Marc is eaten as it is, at room temperature, and at the end of a meal with a wine from the region served at room temperature.

For a piece from the fridge, Fromagerie du Château advises taking it out 20 to 30 minutes before tasting.

BUYING TIPS
Read the milk line

Ask for the base cheese
Les Alpages names Saint-Marcellin. Other pieces may use Rigotte, Picodon or Pélardon.
Check the weight
Weights run from 80 to 150 g, so compare the price against the size you are shown.

Is Aromes au Gene de Marc Safe During Pregnancy?

Fromagerie du Château marks its raw cow's milk piece not recommended for pregnant women because of the raw milk.

The CDC lists soft cheese made from unpasteurized (raw) milk as a riskier choice during pregnancy, and pasteurized soft cheeses heated to an internal temperature of 165°F or until steaming hot as a safer choice.

The NHS says any foods made from unpasteurised milk must be thoroughly cooked, and lists any cheese that's been cooked until steaming hot, including soft or blue cheese, as safe to eat.

Check the label for the milk. For a piece labelled pasteurised, the NHS lists pasteurised soft cheeses as safe to eat, but eaten cold, a pasteurized soft cheese is a type the CDC list does not cover, so ask your midwife or doctor about that piece.
