Everyone is on board with session IPAs. Craft lagers are finally getting their due. “Crushable” is now considered a positive description for craft beers, not a liability. In the craft beer world a decade ago, “imperial” literally ruled, as breweries churned out triple IPAs and 10% versions of every style under the sun. In 2018, that ABV arms race has largely mellowed. But despite American beer drinkers' collective embrace of those easy-drinking, sessionable options, once a beer's ABV dips below 4%, it's not such an easy sell.
