Twelve walnut trees in the garden – for Carmen Irmen, this developed into a genuine passion that led to the Walnut ManufactoryinAscheberg. Step by step, those initial experiments grew into a labour of love that today focuses on artisanal craftsmanship and walnut-based products. At the workshop, special products made from local walnuts are crafted with great dedication – from cold-pressed oil to creative specialities.

TWELVE TREES. A BEGINNING

When Carmen and Michael Irmen moved into their grandfather's house in Ascheberg in 2001, they had no idea that the twelve walnut trees in their garden would one day lay the foundation for a special project close to their hearts. "The trees were just there and nobody could tell me why walnut trees of all things had been planted. So I started to get to grips with them myself - bit by bit, I gathered lots of information about walnuts and tried out lots of things," Carmen recalls.

What began with drying and processing her own harvest quickly became a passion. "In France, we saw how walnut oil is made there. That inspired me," she says. Carmen wanted to make oil from her own nuts. So she bought a small oil press and started her first attempts to make her own oil from her walnut harvest. It takes ten kilograms of nuts in their shells to make one litre of oil - an effort that requires patience and dedication.

PRESSED WITH LOVE: THE WALNUT MANUFACTORY IS BORN

It all started with a small red hand mill, a few walnuts and a lot of curiosity. But it didn't stop at cranking by hand for long: after the first tests, Michael quickly fitted a cordless screwdriver as the drive - "to make it easier to do by hand", as he says with a grin. Hardly any other detail of the grinder was left untouched. For him, technical improvements were part of the process right from the start.

Today, Carmen and Michael run an oil mill specialising in walnuts in the heart of Münsterland. Their walnut manufactory offers people the opportunity to bring their own walnuts and have their own personalised oil pressed from them. Appointments can be arranged for as little as three kilograms of walnut kernels, either with a look behind the scenes during the pressing process or to collect the finished oil later.

Michael, who acquired the necessary knowledge himself with a great deal of patience and tinkering, calls himself a "learning-by-doing oil miller". And Carmen? As the "walnut fairy", she is the soul of the manufactory. She creates an atmosphere, guides the guests and allows them to experience the walnut with all their senses.

The demand for regionally pressed walnut oil and other products made from the local walnut is growing continuously, not least due to a growing awareness of sustainability, healthy eating and artisan foods. However, although interest is growing, many people still don't realise what a valuable treasure they have right in their own garden or on their parents' property. This is exactly where Carmen Irmen comes in: She is passionate about giving walnuts back their rightful place as a valuable natural product. With her work, she wants to contribute to ensuring that the knowledge, traditions and appreciation of walnuts are not lost, but are experienced anew and passed on.

CRUNCH SEMINARS INSTEAD OF SUPERMARKET GOODS

In addition to the oil, Carmen also offers cracking seminars. Not only do they crack together and process their own harvest - there are also tips on correct drying, storage and processing. "Cracking is simply more fun together and it slows things down," she says.

In her small farm shop - open by appointment - Carmen Irmen shows just how versatile walnuts really are. "Walnuts can do so much more than just be on the table at Christmas time," says Carmen enthusiastically. Whether culinary or creative - the lovingly compiled assortment ranges from classic products such as oil and nuts to specialities such as walnut purée, pickled walnuts, tapenade, walnut jewellery and even walnut ink. Each item tells a story of her enthusiasm for what can be created with dedication, craftsmanship and an eye for the region.

REGIONAL. SUSTAINABLE, WITH A LOT OF HEART

Whether at the Christmas market, the farmers’ market or chatting directly on the farm – Carmen Irmen focuses on walnuts from the region. “I don’t want to press nuts from California,” she says. Rather than relying on imported goods, the walnut processing business prefers to use walnuts from local gardens and orchards.

Through products, discussions and seminars, Carmen Irmen aims to raise public awareness of local walnuts. The focus is on regional provenance, artisanal processing and the diversity of walnuts. This creates a range of products that highlights the connection to the region and imparts knowledge about cultivation, processing and use.
