How do I get the viscosity of a mash mixture in brewing?

Click For Summary
SUMMARY

The discussion focuses on calculating the viscosity of a mash mixture in brewing, specifically for a setup involving 1300kg of malted barley and 3250kg of water. Participants emphasize the importance of accounting for the density change of the malt as it absorbs water. Recommendations include consulting with commercial brewers and utilizing BDV viscometers for accurate measurements. The conversation highlights the complexity of viscosity calculations in brewing processes.

PREREQUISITES
  • Understanding of brewing processes and equipment design
  • Knowledge of density changes in mixtures
  • Familiarity with viscosity measurement techniques
  • Experience with commercial brewing practices
NEXT STEPS
  • Research BDV viscometers for accurate viscosity measurement
  • Explore methods for calculating density changes in mash mixtures
  • Consult with commercial brewers for practical insights
  • Investigate existing commercial brewing equipment for viscosity management
USEFUL FOR

Brewers, equipment designers, and anyone involved in the production of beer who seeks to understand and measure the viscosity of mash mixtures effectively.

How do I get the viscosity of a mash mixture in brewing? Please read
Hi, I am designing a mash tun to produce beer. I have 1300kg of malted barley (at a known density) and 3250kg of water. Please could someone outline a method I could use as I am really struggling. One of the main problems I am having is accounting for the density change of the malt when it absorbs water. Are there any online sources that could help? thanks

That sounds like a commercial production level piece of equipment. This is going to vary a lot by the beer, so I'd see if you can get a commercial brewer to discuss it with you or see what existing equipment is out there.
 
There are many brew pubs with enthusiastic owners. Try one!
I agree with @russ_watters - for what you want, you are likely dealing with production equipment. And you are not considering density - of the liquid. Correct?
