A company of entrepreneurs


Who we are

What we stand for

The core objective of Zertus GmbH is to further develop companies and brands in order to expand their market position in the long run and to achieve sustainable growth. Our corporate strategy is based on strong entrepreneurial basic values, such as individual responsibility, the courage to implement renewal and sustainability.

Kinnerton Confectionery

The Zertus subsidiary Kinnerton Confectionery is the fourth largest chocolate producer in Great Britain. Kinnerton Confectionery has its headquarters in London, was founded by Clive Beecham more than 30 years ago and now employs approximately 1,000 people. The company produces more than 10 million Advent calendars in top quality and more than 20 million Easter eggs per year and, thanks to its broad range, is the most important producer of seasonal goods on the island. Kinnerton is also well known for its high innovative strength and its broad portfolio of licensed brands, from Disney to Magnum and Cornetto.


Lir Chocolates

The Irish company Lir Chocolates is the most highly acclaimed manufacturer of premium boxed chocolates in the UK. All products are produced by hand from precious and extremely fresh ingredients before being stylishly packaged.

Lir is also well known for its successful licensing business with major beveragebrands such as “Baileys” and “Guinness”.



As one of the leading producers of high-quality natural products in Great Britain, Humdinger has a wide selection that extends from dried fruits to tasty snacks. Products are distributed under the company’s own brand names “Humdinger” and “Fruit Factory” as well as through British retail brands. The company also markets other licensed products such as Budweiser, Food Doctor, Guinness and Marmite under its umbrella.



Since its foundation in 1976, Bio-Zentrale Naturprodukte GmbH has been among the leading organic food companies in Germany. When it was established, the firm based in Wittibreut-Ulbering initially concentrated on the packaging of flours and mueslis by hand. Today, Bio-Zentrale has a full organic range and, with some 200 products in the biozentrale and BioKids brands, stands for ecological agriculture that interferes with the environment as little as possible while combining the best that nature has to offer.



GAEA was founded in 1995. This name didn’t come about by accident; in ancient Greek mythology, Gaea was Mother Earth – a symbol of fertility and the goodness of the earth. Consequently, the vision of GAEA has been to introduce the world to the benefits of the Greek Mediterranean diet by combining exquisite Greek products based on olives and olive oil with a love of tradition and simplicity.


Partners comment on Zertus

Wilms is able to develop brands in Germany so that they become market leaders in the long term. This is not least possible due to the combined synergies of Zertus.

CESARE MAZZETTI, Owner of Mazzetti and a partner with Wilms

Within the Zertus subsidiaries we act in a market-oriented and entrepreneurial manner. Both of these qualities are important in my job as Export Manager with Dextro Energy, particularly when developing new export countries for our brands.

INES PETERSEN, Head of Export

It’s fun working for Zertus and particularly for Kalfany Süße Werbung. On the one hand, we have entrepreneurial responsibility for the operating business and, on the other, we obtain great benefits from the collaboration within the Group and the services of our independent holding company. This brings us benefits that we would not have as a separate medium-sized company.

ELMAR SCHLESINGER, Managing Director

With its history dating back more than 40 years, Bio-Zentrale is among the German pioneers in the organic market. Distinguished by absolute top qualities and a very well-established brand name, Bio-Zentrale is set to undergo continuous development on the Wilms sales platform in the years to come.
