The Science Behind Perfect Beer Foam

Quick Summary

• Researchers from ETH Zurich and Eindhoven University of technology studied the mechanics of beer foam to better understand its stability.
• Their findings, published in Physics of Fluids (August 26), focus on how proteins stabilize foams during fermentation.
• Key protein, lipid transfer protein 1 (LTP1), was identified as crucial for foam stabilization:

– In single fermentation beers, LTP1 forms spherical particles creating a stable structure.
– In second fermentation brews, yeast alters LTP1 into a membrane-like structure for further stabilization.
– In third fermentation beers like Trappist ales, fragmented LTP1 proteins enhance foam stability by reducing surface tension via Marangoni stresses.

• The study concludes that foam stability is influenced by multiple factors simultaneously and not simply by viscosity or singular interactions.
• Applications for this research extend beyond brewing and coudl help develop safer lubricants in electric vehicles or eco-pleasant surfactants.
