The influence of foam membrane strength on head retention
Visual foam stability | The quality of beer foam depends on many factors, including initial foaming, head retention, lacing and so on. Most foam analysis methods focus mainly on head retention. Using such methods, foam membrane strength for head retention was shown to be an important aspect. Could this factor be responsible for head retention only? And what role do hop bitter acids play in this? The following article summarises some research results which have already been published in BrewingScience, 2021, issue 6: November/December.
