"As you get higher in alcohol, you get less carbonation," Brewer's Association Craft Beer Program Director Julia Herz told Thrillist. "Of most beers in 140 beer styles we track, the majority are less than 6% alcohol. [The beers in Bloomberg's article] are experimental beers and not a common example."
Herz went on to point out that most of the beers mentioned were more like ways for brewers to flex their beer muscles. Or, better stated, their innovations in brewing, such as cask-aging and freeze-distilling. But there's a rub with all these beers: they're exorbitantly expensive for the producer and consumer. Utopias, the most widely available of these beers, costs $200 per bottle.
"I dispute the fact that it is a trend," Herz said, continuing that the headline gives the consumer the wrong impression. "The use of the word 'flat beer' in the title and 'flat beer trend' is misleading. That insinuates the beer should have been carbonated in the first place."
