The Aeration Unit for Craft Brewers
GEA WORTSTAR Craft Wort Aeration
The semi-automatic wort aeration system for craft brewing solutions − DN 25 up to DN 50
Top marks for a novel aeration principle
After cooling the wort is oxygenated to increase yeast activity and to start the fermentation process.
When the wort flows into the aeration nozzle, it creates a partial vacuum and air is entrained with the wort. This leads to an excellent bubble size distribution and thus to a large contact surface for oxygen uptake by the wort.
The GEA aeration unit – easy introduction of sterile air into the wort
With the aeration unit, sterile air is introduced into the wort through the defined annular gap of the annular gap nozzle. The complete annular gap nozzle can be CIP cleaned and sterilized with steam. The system is the standard for obtaining the optimum yeast flotation and activity, and more precise fermentation curves. This guarantees superior quality beer.
Your benefits at a glance:
- Continuous and exact wort aeration
- Fine and even introduction of air into the cold wort through an annular gap nozzle
- Optimum oxygen uptake by the wort is ensured due to finest air bubbles
- Consistent hygienic design
- Easy CIP cleaning
- Completely pre-assembled system

How SmartParc is rewriting the rules of food production
Thanks to a new SmartParc manufacturing site, food processors in the U.K. are cutting their running costs and emissions. With GEA heating and cooling technology at its core, this collaborative production model demonstrates how innovation is accelerating the industry’s net-zero ambitions.
The food science playground
“Brewing eggs is like brewing beer.” It’s the kind of comparison that makes you smile – and then it clicks: Something complex suddenly feels simple. Through this personal film, set in the agricultural heartland of the U.S., we explore precision fermentation and the real-world work it takes to turn an idea into food.
