American drinkers are abandoning beer for harder stuff, squeezing the world’s biggest brewers.

Anheuser-Busch InBev SA, Molson Coors Brewing Co. and Heineken NV all reported sharply lower U.S. beer volume in the first quarter compared with a year earlier as drinkers turn to other alcoholic beverages, such as wine or whiskey.

AB InBev said its volumes fell 4.1% in North America, partly because of weakness in the company’s core Bud and Bud Light brands. Last month, Heineken said its volumes fell by a high-single-digit percentage in a declining U.S. beer market, without being specific. And last week, Molson Coors said its U.S. sales fell 5.8%, driven by a 3.8% drop in domestic brand volumes. That sent its share price tumbling 15% in a single day, to a four-year low.

Executives blamed a much colder start to the year compared with 2017, when warmer weather drove brisk sales. Despite the volume drop, AB InBev said it raised prices and boosted revenue per hectoliter. Strong volumes in markets such as Mexico, Colombia and Argentina helped, too. Shares rose early Wednesday in Belgium, before ending the day flat.

Still, the industrywide volume declines were sharper than expected, punctuating years of slowing growth amid broader headwinds.
