Social psychologists will say beer evolved to match what people like while evolutionary psychologists will say we evolved to like the beer that gets us a date. Social psychologists win this one because women, that evolutionary target of men, who are the primary drinkers, don't play by the rules regarding beer foam they should play by if biology were the issue.
Beer foam: The Gender Gap Does beer foam need some sort of outreach program? Are women biased against it? It might explain why men drink more beer. Beer is a total package, it has an aesthetic and a taste but color and foam are the most striking things people first notice in beer. What foam is left over on the glass after the beer, the 'lacing' as experts call it, impacts the perception also. As I said, beer evolved to match what people like - because people buy what they like, not what is available, over the long haul - and people seem to like 'the middle' when it comes to foam; not too much and not too little or else it gives them ideas about its quality and even its alcohol content.
But not all people. While all people had a preference for how 'clean' they like the glass to be when finished and therefore how much lacing there was a real gender difference in how much lacing women wanted. Conclusion: It may be that the market for lace in beer, much like in a Victoria's Secret, is not women at all. Are the Scottish anti-science about beer foam?
Sure, the northern Europeans are most famous for beer but Scottish people drink too. Celtic fans need to do something while waiting for the match to be over so they can headbutt Rangers fans and then kick them when they are on the ground, and whisky is too expensive to drink for two hours. The science is settled, the consensus is clear; foam matters, it is a harbinger of beer to come. Yet not everyone accepts its importance. The wrong foam was perceived by Americans as being lower quality and even less alcoholic.
They also felt like more foam meant it came from a dirtier glass. That last part is incorrect but Americans were at least thinking about the foam.
The Scottish cared about foam the least of all countries tested. Conclusion: the Scottish are anti-science about beer foam. At least they got haggis right. The Physics and Chemistry of Beer Foam I can't go into too much detail here because we are talking about a 60 page book on beer foam in which not a single paragraph is wasted.
I would have to write pages to cover everything. You should obviously just buy the book if you want to know the true nuts and bolts of foam. I can tell you that, were it legal, beer foam would be a great way to teach high school students about science.
There is a science reason 1,, bubbles in the foam of a glass of beer play so nicely and that reason is surface tension and surface-active molecules. The nucleation we have come to know and love about beer foam is a vital aspect so by all means get annoyed if a bartender or waiter thinks he is doing you a favor gently pouring your brew down the side of a glass.
He is cheating both you and science. Bamforth cleverly relates viscosity in beer to baseball fans in Wrigley Field, a metaphor you can appreciate if you like teams that cannot win Big Games. These beer guys know applied chemistry in a way that is dizzying so they do what they can to mitigate anti-science waiters pouring beer down the side of the glass. That means foam-stabilizing materials and terms like proteolysis.
Trust me, they care about foam so you don't have to. J Inst Brew, , Kanauchi, M. Brew, , Lee, Y. Jackson, G. UK Patent 2 Bamforth, C.
