Case study

Challenge: For years, this international brewer had used the same product for hemicellulose breakdown in its recipes, which go from 10-40% barley. But the brewer faced variable filtration performance in the brewhouse and downstream (beer filtration) as well as extract yield variability.  

To control filtration performance, they tended to overdose depending on the crop quality. The brewery is capacity constrained in the brewhouse and filtration department. 

Solution: Ultraflo® Prime, which was dosed on the barley proportion of the recipe, resulted in predictable filtration performance in the brewhouse and beer filtration without variability. The solution increased total beer filtration batch size with a single filter run by 10%. The Kieselgur bodyfeed was also slightly reduced, enabling longer filter runs.  

In addition, mash filtration improved. Using a mash filter, the sparging pressures were reduced by almost 10%, leading to more stable performance. Adjusted mash filter settings also led to better extract yields and shorter filtrations. 

Using Ultraflo® Prime in recipes from 0-20% raw barley introduction can even enable undetectable beta-glucan levels.

Troubleshooting a process bottleneck

Challenge: Something was making a regional brewer’s lautering process take much longer. And the brewer couldn’t produce the amount of beer required due to the longer brewing cycle time.

Entering a profitable new market

Challenge: An international brewer wanted to enhance profitability and enter a new market. Having already highly optimized its raw materials, the challenge was to increase RDF/attenuation to the highest possible level.

3 X lower dosing rate cuts costs and boosts sustainability

Challenge: Production of a regional and international brewer’s ultra-low-carb beer used a glucoamylase that required a very high dose rate. This created unnecessarily high costs on multiple areas.
