Komijnekaas is both made and aged by Treur Kaas, a business which was launched by Evert Treur, a farmer’s son, in 1955. The company began when Evert started selling cheese sourced from local farmers, from the back of his bicycle, to the local neighbourhood and cheese shops. By the end of that same year, he was successful enough that he needed a car and small warehouse, but could only initially buy one big enough to store 100 cheeses. Demand grew and Evert was able to buy larger and larger buildings, which he converted into warehouses, that could store 16,000kg of cheese initially, then 30,000kg, 120,000kg and finally 320,000kg of cheese. In 1981, the family built their own storage and maturing unit in Woerden, large enough to store 500,000kg of cheese. In 1995, Evert turned 65 and decided to retire, passing the business onto his sons. He was awarded a medal of honour for his contribution to the industry, having worked within it for 40 years.
