WDK Onions is already the 3rd generation of the De Koster Family that is active in the onion trade. WDK Onions is a real family business.

In 1933 Willem de Koster started sorting and trading onions. This was mainly done manually.

In 1981 the company was taken over by the sons Rinus, Kees and Piet de Koster. They have expanded the name of the De Koster family into a well-known name in the onion world. It's not about quantity but about quality. This has always been the motto at W de Koster & zonen B.V. They were ahead of their time by investing in a new computer weigher and sorting line upgrades in the 1990s.

In 2009 Mike de Koster took over the family business. The trade name was then changed to WDK Onions. The company has continued in the same tradition, "supplying an above-average quality onion". In this way the De Koster family will be a well-known name in the onion world for a long time to come. The 4th generation is already learning everything about the onion, but they will have to be patient for a while.

In 2020 WDK Onions has developed its own brand. The brand has been given the name "Jolie", named after Mike de Koster's daughter. Jolie means "beautiful" in French. For WDK Onions this also means that we pack beautiful and high-quality onions in these bags.
