Leerdammer (Dutch pronunciation: [leːrˈdɑmər]) is a Dutch semihard cheese made from cow's milk. It has an ageing time around 3–12 months. It has a creamy white texture and was made to be similar in appearance and flavor to Emmental, but it is rounder in taste. Its sweet and somewhat nutty flavour becomes more pronounced with age. It also has distinct holes. In a past advertisement campaign, this was made use in claiming jokingly that "the taste is around the holes"[dubious ].
The cheese is produced exclusively by the Groupe Bel. The Leerdammer name is a trademark of Bel Leerdammer B.V. On 22 March 2021, Groupe Bel announced is was handing over the brand and its related assets to Lactalis in exchange for the shares Lactalis detained in Groupe Bel, bar a retained 0.9% stake.
Leerdammer cheese is produced in Schoonrewoerd in the municipality of Leerdam, the city which gave Leerdammer its name. Generic Leerdammer-style cheese is sold as Maasdam cheese. Groupe Bel has a second factory producing Leerdammer in Dalfsen, in the eastern province of Overijssel. It is also produced in France
The cheese was developed by Cees Boterkooper, who had owned a small dairy in Schoonrewoerd since 1914, and Bastiaan Baars, who ran a cheese shop in a nearby village. The two met in 1970, and soon afterwards decided to collaborate. They worked on a cheese that could compete with Gouda and Edam. Leerdammer was launched in 1977. It is also available in supermarkets throughout Europe, Russia, and the US
