How Americans Substituted Coffee in WWII (Ersatz Drinks)

During World War II, Americans did not just fight with weapons. They fought with ration books and creativity.

And when coffee, the lifeblood of mornings, was rationed, folks did not panic. They adapted.

Enter ersatz coffee. A fancy term for “not-the-real-thing” coffee. Some of it was pretty bold. Some of it tasted like roasted disappointment. But all of it tells a story.

What Does “Ersatz” Actually Mean?

Ersatz is a German word that literally means “replacement” or “substitute.”

It entered English during WWI, when German blockades forced Europeans to improvise with ingredients on hand. By WWII, the word had spread into everyday American use.

An “ersatz coffee” was any drink designed to mimic coffee without actually being coffee. Sometimes the substitute was commercial and sold in boxes. Sometimes it was homemade and roasted in a cast iron skillet.

Either way, the goal was the same: preserve the morning ritual when the real thing was gone.

Why Coffee Disappeared From American Kitchens

Coffee was not grown in the continental US. Almost every bean had to ship in from Brazil, Colombia, and Central America.

Once the US entered the war in late 1941, ships that had been hauling coffee were needed for military supplies. German U-boats targeted cargo routes in the Caribbean.

By November 1942, coffee was officially rationed. Each adult over 15 was allowed one pound of coffee every five weeks.

That works out to roughly one cup of moderate-strength brew per day. For most Americans, who were drinking three or four cups, it was a shock.

People were told to “make do.” For many, skipping their morning cup was not an option. Coffee was not just a drink. It was a ritual. A comfort. A piece of normalcy during a very not-normal time.

What Ersatz Coffee Was Actually Made Of

This is where things get weird and kind of brilliant.

Homemade or store-bought, ersatz coffee was brewed from stuff like:

• Roasted chicory root (still popular in the South today)
• Ground barley, rye, and wheat
• Corn kernels roasted to a deep brown
• Toasted acorns or soybeans
• Dandelion root, dug up from the yard and dried

None of these had caffeine. But they were warm, brown, and smelled sort of like coffee if you squinted your nose.

Chicory stood out as the fan favorite. It had a bitterness that kind of fooled your brain into thinking you were drinking coffee. People mixed it with whatever they had or brewed it straight.

Chicory: The American South’s Secret Weapon

The South had been drinking chicory coffee since the Civil War.

When Union blockades cut off coffee supplies to the Confederacy in the 1860s, New Orleans cooks started roasting and grinding chicory root as a stretcher. The habit stuck.

By the time WWII arrived, chicory coffee was already a regional tradition. Brands like Cafe du Monde had been selling it for decades.

Chicory root has a deep, earthy bitterness that mimics dark-roasted coffee. Paired with milk and sugar, it becomes that classic New Orleans breakfast drink served with beignets.

When coffee rationing hit in 1942, the rest of America finally caught on. Chicory went from regional curiosity to nationwide substitute.

Postum: The Commercial Ersatz Brand

Not every family wanted to roast their own substitute. For those who did not, Postum was the go-to.

Postum launched in 1895, invented by C.W. Post as a caffeine-free coffee alternative. It was made from roasted wheat bran, wheat, and molasses.

During WWII, Postum’s sales exploded. The company pitched itself as patriotic: save the coffee for the troops, drink Postum at home.

Postum is still sold today, mostly as a nostalgia product. The formula has barely changed.

If you ever want to taste exactly what your grandparents sipped while reading war bulletins, a jar of Postum is as close as you can get without a time machine.

How People Actually Made It Work

It was not just about taste. It was about holding on to a daily habit.

Coffee substitutes helped people feel like life was still under control, even if the world was not.

Families passed down recipes. Home economists taught how to roast your own “beans” at home. Government pamphlets promoted the idea. This was not gourmet. It was survival with a ceramic mug.

Sometimes people blended the substitutes with whatever real coffee they had left to stretch it further. A teaspoon of the real thing. A whole scoop of roasted grain. It worked. Kind of.

These coffee substitutes were the companion to the plainer wartime morning. The drinks paired naturally with toast, porridge, and whatever else made it into our wartime breakfast recipes collection.

The European Version: Muckefuck and Malzkaffee

Germans had their own ersatz tradition, much older than the American one.

“Muckefuck” (pronounced moo-keh-fook, and yes, everyone giggles) was a slang term for coffee substitute, dating back to the 19th century. “Malzkaffee” (malt coffee) was the more respectable name.

Both were roasted from barley, rye, or chicory. German civilians drank it through two world wars, then kept drinking it out of habit.

For a faithful recreation, our Muckefuck ersatz coffee recipe walks through the grain-based method.

British civilians faced similar shortages but generally switched to tea rather than coffee substitutes. Tea was rationed too, but less aggressively. The full picture of UK rationing is in our UK wartime rations guide.

How to Make Ersatz Coffee Today

If you want to try it, the easiest starting point is chicory.

Buy already-roasted chicory root or grind your own. Use it like coffee grounds: about one tablespoon per cup, brewed in a French press or drip cone.

A French press is the most forgiving brewing method for substitutes, since the grinds are coarser and the extraction is gentler.

Want to roast your own substitute? Dandelion root works well. Dig up fresh roots in spring. Clean, chop, and dry them thoroughly.

Roast the dried root at 350F on a sheet pan until deep brown and fragrant, about 25 minutes. Grind coarsely. Brew as coffee.

For a period-accurate pairing, serve it alongside victory bread with a thin scrape of jam. That was the authentic wartime breakfast for millions.

Did Anyone Actually Like It?

Let us be honest. Most people knew this was not good coffee.

But they appreciated the effort. It gave them a little comfort. A warm drink on a cold morning still counted for something.

Some even got used to it. When the war ended and real coffee came back, not everyone went running to the store.

A few stuck with their strange brews out of habit, thrift, or plain old stubbornness. Postum continued to sell steadily into the 1960s.

In the South, chicory never left. Drive into New Orleans today and you will still find it sitting next to the coffee beans on every shelf.

Ersatz Coffee FAQs

Does ersatz coffee have caffeine?

No. Almost every WWII substitute was caffeine-free, since chicory, grains, and roots do not contain any.

This is actually why some people preferred it. You could drink it at night without losing sleep.

Is chicory coffee bad for you?

In normal amounts, no. Chicory root is high in inulin, a prebiotic fiber that is actually good for gut health.

Excessive amounts can cause bloating. Moderation, as always, matters.

How does acorn coffee work? Are acorns not toxic?

Raw acorns contain tannins, which are bitter and hard to digest in large amounts. Traditional preparation involved leaching the acorns in multiple changes of water for several days before roasting.

Properly processed acorns make a dark, bitter, coffee-like drink. Native American and European peasant cooks had been doing this for centuries before WWII rolled around.

What is the best substitute if I want to try one today?

Chicory is the closest flavor match to real coffee. Roasted dandelion root is a close second.

Postum is the easiest commercial option if you do not want to brew anything.

Why did Americans not just grow coffee domestically?

Coffee plants need a tropical climate. Hawaii was the only US territory producing coffee, and Hawaiian output was nowhere near enough to meet mainland demand.

Puerto Rico also grew coffee, but shipping disruptions made even that supply unreliable.

When did coffee rationing end?

Coffee rationing ended in July 1943, earlier than most other food rationing. The war continued, but shipping routes had stabilized enough to let civilian supplies flow again.

Sugar rationing, by contrast, continued until 1947.

Why This Still Matters Today

This story is not just about weird drinks. It is about how people deal with shortages.

They do not always need fancy tech or gourmet replacements. Sometimes they just need hot water, roasted seeds, and determination.

Americans did not let a global war take away their morning coffee break. They improvised. They shared what worked. They sipped their acorn-chicory blends and got on with the day.

Honestly, that is kind of inspiring. Even if it tasted like burnt cereal.

If you ever want to try ersatz coffee for yourself, just for the history of it, start with chicory. Brew it strong, drink it black, and toast to the people who made coffee out of literally anything.
