Milbenkäse, called Mellnkase in the local dialect and often known as Spinnenkäse, is a German speciality cheese. It is made by flavouring balls of quark with caraway and salt, allowing them to dry, and then leaving them in a wooden box containing rye flour and cheese mites for about three months. An enzyme in the digestive juices excreted by the mites causes the cheese to ripen. Milbenkäse is said to taste similar to Harzer cheese, but with a bitter note and a distinctive zesty aftertaste. Mites clinging to the cheese rind are consumed along with the cheese. Historically, the cheese was produced in the Zeitz and Altenburg districts of the Saxony-Anhalt / Thuringia border region; today it is produced exclusively in the village of Würchwitz, in the state of Saxony-Anhalt. memorial at Würchwitz The traditional method of making Milbenkäse, which dates back to the Middle Ages, was nearly lost by 1970, with only the elderly Liesbeth Brauer knowing the technique. Local science teacher Helmut Pöschel was taught the proper way to make it and together with his associate, Christian Schmelzer, succeeded in revitalizing the tradition. A Cheese Mite Memorial was later erected at Würchwitz to celebrate the renaissance of Milbenkäse production.
Production
flavoured with salt and caraway is shaped into small balls, cylinders or wheels, and dried. Then it is placed in a wooden box containing rye flour and inhabited by Tyrophagus casei mites for at least three months. The digestive juices of the mites diffuse into the cheese and cause fermentation; the flour is added because the mites would otherwise simply eat the whole cheese instead of just nibbling away at the crust as is desired. After one month, the cheese rind turns yellow; after three months, reddish brown. Some producers allow the cheese to ripen for up to one year, until it has turned black.
Legality
Milbenkäse falls into something of a legal grey area: EU Regulation 178/2002 allows the sale of foodstuffs containing living animals if they are "prepared for placing on the market for human consumption". On the other hand, cheese mites or their digestive juices are not explicitly permitted as additives for cheese according to the relevant German food ordinances. Milbenkäse is produced under a permit by the local food safety office and HACCP compliance of the product is enforced.
Similar cheeses
Cheese mites are used in cheese maturing elsewhere. The most famous example is probably Mimolette from northeastern France and nearby Belgium. Other French cheeses - mainly from the Massif Central, the French Alps and the Pyrenees - sometimes host cheese mites in their crust more or less by accident. But most of these cheeses are semi-hard to hardrennet cheeses, whereas Milbenkäse is a softer sour milk cheese. The SpanishCabrales cheese of the Asturias region also contains living cheese mites, though they are few in number, inhabit the mould canals, and take no significant part in the maturation of this blue cheese. Another cheese that contains living animals is the Sardinian casu marzu, which contains maggots of the cheese fly.
