How to implement beer netting in the brewing process?


Greenflex is constantly researching new products and possibilities. This is why we started investigating other markets that could use our netting. Thanks to our network, we came into contact with the beer brewing industry. By understanding how the art of brewing works, we started to realize our process nets could be implemented during several stages of the brewing process.

Recently, we had meetings with BarthHaas, a leading global supplier of hop products and beer brewing innovations. They used our alternative hop bag for a dry hopping test in their campus brewery in Nuremberg. 

“Using a net in a keg is the best method for us to test different hops in the same base beer. The method is simple, the handling easy, no off-flavors, perfect.”

The brewing process

We mapped out the brewing process during our research and explored with several brewers from Belgium, Germany, and the Netherlands where and how to implement our hop bags. With success, our netting can indeed improve the brewing process. The nets can be used to add hop pellets in four different stages: the boiling process, the whirlpool process, the fermenting process, or the maturation process. Additionally, you can use it for herbal infusions or applications with wood chips. Gert De Rouck, manager pilot brewery at KU Leuven, did a test on our nets as well. During the testing phase, several advantages came to light.

"We have tested the Greenflex net at our KU Leuven pilot brewery and were astonished by its flexibility. The net can be used throughout the whole brewing process. Moreover, even during flushing from one process through another; put the net with the aromatic compound in a tank, flush it with beer to create dynamic extraction and save time during production."

Applications of beer netting

In short

Our beer nets can be implemented during several stages in the brewing process. Simplify your brewing tools using our hop netting. They are the ideal replacement for hop bags, hop baskets, or your hop extractor. Flexibility is key when using our hop bags. Their easy-to-use design, light character, and small meshes improve the brewing process efficiently. 

The possibilities are endless, and we can offer pre-cut pieces, rolls, and even sterilized netting. Interested in how we can help? Feel free to contact us or visit our product page

Sustainable beer netting

Our R&D game is strong. Greenflex has been researching new ways to make its products greener and more sustainable. That is why we started experimenting with biodegradable yarns. Our yarn’s fibers originate from renewable organic sources. During the production of the yarn, an environmentally responsible production process is maintained.

The fibers enable the yarn to be fully compostable and biodegradable, making sure the net can fully return to nature. On top of being environmentally friendly, the yarn outperforms other yarns when it comes down to tensile strength. Interested? Request more info below!
