Preparation, packaging, logistics.
From the field to delivery: Rathgeb BioLog AG in Unterstammheim washes, trims, sorts, packs, stores, picks and delivers organic vegetables and potatoes. Everything from a single source and ISO 9001 certified.
Today, 0 litres of trimmings have already gone to the neighbouring biogas plant.
On the product: quality starts in the field.
Before we wash or pack anything, it is sown, tended and harvested. The quality we later stand behind is created in our fields in the Stammertal and in our greenhouses.
Preparation: washing, trimming, sorting.
Every delivery is checked, weighed and given a batch number. Then it is washed, trimmed by hand and sorted. Because we do without chemical-synthetic agents, washing is mainly about one thing: making sure the vegetables look as crisp as they are.
Cut, mixed, ready to cook? Convenience products are available from our sister company Kellermann.

Packaging to customer requirements.
Sorted, trimmed and packed – in the packaging unit that suits each point of sale, and in our customers’ label programmes. Labelled with all producer details so the vegetables can go straight onto the shelf.

Storage at the optimal temperature.
After harvest almost everything is chilled immediately – and stays chilled until it reaches the customer. Carrots and potatoes are stored in our own hall in Unterstammheim. Fresh vegetables, on the other hand, we often do not store at all: they leave on the day of harvest.

Order picking: ready for the trade.
We put together our customers’ orders and prepare them for the trade – quantity, variety and container as requested. This way the vegetables reach the shelves without detours.

Logistics: transport and container management.
Tomatoes like it above 16 °C, leaf salads just above zero. With our own refrigerated vehicles we maintain the cold chain without interruption. And we manage the containers so that they are where they are needed in good time.

The final quality check is always done by a person.
