Milbenkäse (" mite cheese"), called Mellnkase in the local dialect and often (erroneously) known as Spinnenkäse ("spider cheese"), is a German specialty cheese made from Quark and cheese mites's feces. Historically, the cheese was produced in the Saxony-Anhalt/ Thuringia border region of Zeitz and Altenburg districts; today it is produced exclusively in the village of Würchwitz, in the state of Saxony-Anhalt.
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 Milbenkäse and together with his associate Christian Schmelzer managed to revitalize the tradition. A memorial was later erected at Würchwitz to celebrate the renaissance of Milbenkäse production. The rear side of the memorial is hollow and is regularly stocked with small bits of Milbenkäse for passersby and tourists to try.
Milbenkäse is said to taste similar to Harzer cheese, but with a bitter note (increasing with age) and a distinctive zesty aftertaste. Mites clinging to the cheese rind are consumed along with the cheese.
