Nonalcoholic beer's rapid growth is slowing, casting doubt on its long-term prospects within the struggling global beer market. Once a niche for major brewers, NA beer now makes up about 2% of global volume, with growth slowing to single digits. The U.S. outperforms with 16% annual gains, but broader momentum cools. Companies focus on improving taste and marketing for casual, stigma-free consumption. Market analysts see NA beer as a necessary adaptation as younger consumers drink less and health trends impact sales.
