How WWII Turned Beer into a Weapon (And Ruined American Taste)

World War II did something surprising for American beer. It turned yesterday's villains into patriots and created a generation of lager drinkers who'd shape American beer culture for the next 50 years.

During WWI, German-American breweries were labeled as "enemies of the people" due to anti-German sentiment, and Prohibition nearly wiped them out entirely.

But when WWII kicked off, beer became essential for troop morale, and suddenly those same breweries, i.e., Anheuser-Busch, Pabst, Miller, were patriotic heroes supplying the war effort.

Beer Becomes a Military Weapon. You Said What?

The U.S. Department of Agriculture ordered that 15% of all beer production be set aside for the troops, and brewers were more than happy to oblige.

They saw it as an opportunity to restore their reputation and "cultivate a taste for beer in millions of young men who will eventually constitute the largest beer-consuming section of our population."

They weren't wrong.

The government limited beer sold to service members to 3.2% ABV as a compromise with anti-alcohol politicians.

But even weak beer was better than no beer, and soldiers drank it by the case.

Olive Drab Cans and Floating Breweries

In 1944, the military switched to olive drab cans to camouflage them from enemy aircraft.

Meanwhile, the British Royal Navy designed "floating breweries" capable of producing 250 barrels of beer per week to supply sailors in the Pacific.

American troops received regular beer rations, and for many soldiers, it was their first real exposure to German-style lager.

They developed a taste that would last a lifetime.

The Bland Beer Legacy

Here's where it gets controversial.

WWII beer rations are partly responsible for why American beer became so bland.

The palates of a generation of American soldiers grew accustomed to the weak beer that was standard in military rations.

When they came home, they wanted more of the same, light, easy-drinking lager.

Breweries followed suit, creating even lighter versions that dominated the market for decades.
