Hermelín Cheese 45%

The best-known name, "Sedlčanský hermelín", is a registered trademark rather than a regional designation: since 2019 it has been made in Vysočina, not in Sedlčany, and Hermelín is produced by several Czech dairies. Commercial variations include the flagship Král Sýrů ("King of Cheese") brand, under which Hermelín has been sold since 1993. Fat content typically ranges from 45% to 50% in dry matter, with 45% representing the standard offering—rich yet not overly indulgent. Some producers offer seasoned versions with herbs or pepper incorporated into the rind, as well as creamier "double cream" iterations for those seeking more luxurious textures.

Hermelín's story begins in the 1920s, when Czech dairies—first in Přibyslav on the Bohemian-Moravian Highlands—set out to replicate the celebrated French Camembert using local milk, selling it simply as "Camembert." Production in the small town of Sedlčany, with which the cheese became synonymous, began in 1954. In the mid-20th century Czech cheesemakers gave their creation its own name: "Hermelín"—Czech for ermine—inspired by the cheese's snow-white mold rind, which evoked the luxurious fur adorning royal cloaks. The name was registered in 1946, though "camembert" remained in common use until around 1970. The name stuck, and Hermelín evolved from imitation to institution. Today, a century after the first Czech camemberts, the cheese has long outgrown its imitation beginnings. It stands as one of the most consumed cheeses in the Czech Republic and a cornerstone of Czech culinary identity, with Král Sýrů its best-known brand.

The transformation of fresh curds into the luscious, aromatic wheel of Hermelín is orchestrated by Penicillium camemberti, the white mold responsible for the cheese's signature bloomy rind. This fungus secretes powerful proteinases and lipases that work from the outside in, breaking down the casein protein matrix and milk fats through proteolysis and lipolysis. As these enzymes cleave peptide bonds, they generate free amino acids—precursors to the volatile compounds (alcohols, ketones, aldehydes, and esters) that define the cheese's aroma. The high moisture content (~50%) accelerates mold growth and ripening, allowing the cheese to reach peak creaminess within 4–6 weeks. Secondary microflora including Kluyveromyces lactis, Geotrichum candidum, and Brevibacterium linens contribute additional enzymatic activity and flavor complexity. The 45% fat in dry matter provides the substrate for lipolysis, yielding free fatty acids that contribute buttery, slightly tangy notes. Temperature and humidity during affinage are critical: too warm, and the mold overgrows, producing bitter off-flavors; too cold, and ripening stalls, leaving a chalky core.

Hermelín is made from pasteurized cow's milk by several Czech dairies; the well-known "Sedlčanský hermelín" is a brand name and has been produced in Vysočina since 2019. Major producers like Král Sýrů (owned by Savencia Fromage & Dairy) have modernized production while maintaining traditional recipes. When purchasing, look for Czech-origin labels to support authentic producers. Vegetarians should verify rennet sources, as traditional production uses animal-derived rennet, though some modern versions employ microbial alternatives. The cheese's relatively modest price point reflects efficient industrial production, making it accessible while still delivering artisanal character.
