How Foam Is Becoming a Selling Point at Breweries | SevenFifty Daily

American beer drinkers often treat foam as a flaw, not a feature, expecting mugs to brim with beer. Begone, bubbles! Big mistake. Foam is an indicator of a capably constructed beer, and a fluffy cap helps capture fast-vanishing volatile aromatics and protect beer from ruinous oxygen. Varying levels of foam can also impact a beer’s carbonation level, leaving it crisper or softer and better tailored to different food.

For SevenFifty Daily, I look at how bars and taprooms are increasingly pouring beers to precise, and sometimes purposefully excessive, foamy heights. The bubbly pageantry offers consumers a compelling reason to pony up for pints in person.
