We strive for the highest quality. We stand by our word.
Experience has brought us to where we are today. For generations, it has proven essential to stay at the forefront of technology and leave nothing to chance. That’s why flawless quality is our top priority.
Paper can be patient. But for us, quality is more than just a promise.
At every stage of the production chain, our comprehensive quality management system is firmly in place. Only products that are free from contamination and meet the highest hygiene standards are allowed to leave our mill.
Strict adherence to detailed analysis plans is ensured, and every department places special emphasis on maintaining the highest levels of hygiene.

Free from genetic engineering
Rooted in tradition and driven by conviction, we use only natural ingredients.
All raw materials used originate from certified non-GMO cultivation. To ensure GMO-free quality, we rely on binding agreements with our suppliers as well as regular analyses of raw materials and finished products conducted in our in-house laboratory.

Grain partners
We want only the best.
For us, quality comes first, and that starts with a raw ingredient free from chemical additives. That’s exactly why we carefully inspect our suppliers. That is the only way we can guarantee that only the highest-quality grain goes into our flour. To maintain and even improve that quality, we test every single grain in our in-house lab.

In-house lab
Highly technological mills like ours leave nothing to chance.
We inspect, test and optimise on a daily basis. Because experience has shown that, only through regular checks can quality be guaranteed. During production, we take samples which are then examined according to exact analysis plans. In addition to checking the status quo, we challenge it and find out how we can produce even better flour.

We are collectors of certificates.
We’re happy to be inspected.
You can claim a lot of things. But we want to prove that we do everything humanly possible to ultimately provide the best flour. That’s why, in addition to our Green Energy certificate, we’ve also received the IFS certificate from Quality Austria. We’ve also committed to participating in the European Grain Monitoring Programme. Our products are examined down to microbiological parameters. In summary: we have nothing to hide!

Attention bakers!
We’re happy for you to have a look behind the scenes.
If you don’t believe it, just come and see for yourself. Just like the open kitchen in a gourmet restaurant, we’ve got nothing to hide and warmly welcome regulars and anyone interested to our mill. Anyone touring the mill for the first time is sure to have a few “Aha!” moments. You won’t find any idyllic, old-school river-mill nostalgia at Rieper. Rather, our operation is state of the art and runs with the utmost precision.
