Chicory (Cichorium intybus): The Roadside 'Coffee' Napoleon Made a National Drink, the 1906 Pure Food Act Made a Fraud, and the 2018 FDA Made a Fiber Superfood

What is Chicory?

In New Orleans, people line up around the block for a cup of coffee that hides a small secret. A good part of what is in that cup is not coffee at all. It is the roasted root of a plant growing wild in the gravel along the highway. And for one strange stretch of American history, putting that root in your coffee was treated as a crime.

Slip it into a tin of ground coffee in the eighteen eighties, and you were a clever merchant stretching a dollar. Do the same thing twenty years later, and a government chemist could seize your goods and call you a fraud. The root never changed. Only the law did.

The plant behind all of this is chicory (Cichorium intybus) - the tall, stiff-stemmed roadside plant whose pale sky-blue flowers open every summer morning and close by early afternoon. Underground grows a thick pale taproot, and that root has served three centuries as three completely different things: a wartime coffee rescue, a coffee fraud, and a premium fiber. Same plant. Three verdicts. Nothing about the root ever changed - only what we decided it was worth.

From Napoleon's 1806 Blockade to New Orleans & the Civil War Coffee Scarcity

~1766: Frederick the Great Squeezes Coffee Imports

The chicory-in-your-coffee story starts almost forty years before Napoleon. In the 1760s, Frederick the Great of Prussia was watching too much of his kingdom's silver leave to buy imported coffee. He restricted the imports to protect the treasury. His subjects reached for what grew in their own fields: they dug the pale taproot of the roadside chicory, roasted it dark, and brewed it in place of the beans they could no longer afford. It was a first draft. But it was a draft in one country, and it stayed local.

1806: Napoleon's Continental System

The habit that would change a continent came from Napoleon Bonaparte. He could not defeat the British navy, so he tried to ruin Britain economically with a continent-wide embargo he called the Continental System, declared in the Berlin Decree of 21 November 1806. One casualty of that embargo was coffee. The beans that reached Europe by British-controlled sea routes stopped arriving, and across France the morning cup went empty.

The French answer grew in their own fields. Roasted dark, ground, and brewed, the pale chicory root poured a bitter, nearly-black drink that looked like coffee and carried its own deep, nutty flavor. The drink took a name of its own: cafe chicoree. And here is the part that mattered. When the blockade lifted and real coffee flowed again, the French kept it. They had grown to love the taste - the bitter, roasted, faintly-toffee note of chicory alongside coffee - and they carried the habit with them across the ocean.

New Orleans, Rose Nicaud & the 1862 Opening of Cafe du Monde

The habit found its true home in New Orleans. This was a French city at heart, and long before any trouble started, its people had already folded chicory into their coffee out of pure preference. Then the trouble started.

When the American Civil War came, New Orleans was the second-busiest coffee port in the entire country, its docks stacked with beans bound up the Mississippi. The Union navy shut that harbor down. What the British blockade had done to Napoleon's France, the Union blockade now did to the South. Coffee turned scarce, and then it turned ridiculous. Over the course of the war, a pound of coffee in the Confederacy climbed from about $1.20 to nearly $200.

So New Orleans leaned harder on the root it already trusted. People stretched their last real beans by cutting them with roasted chicory, and when the beans ran out completely they drank it alone. One of the vendors who kept that habit alive was a formerly-enslaved woman remembered as Rose Nicaud, who sold coffee in the city's open markets and became something of a local legend. A small coffee stand that opened in the French Market that same year, 1862, was Cafe du Monde, and it has been pouring coffee cut with chicory every day since.

When the war finally ended and the ships returned, the rest of the country dropped chicory without a second thought and went back to pure coffee. New Orleans never did. There, it had stopped being wartime thrift and become something closer to identity.

Inulin, the 1995 Gibson & Roberfroid Prebiotic Paper & the 2018 FDA Fiber Recognition

What Inulin Actually Is

Deep inside the chicory taproot sits a specific fiber called inulin. Chemically, it is a fructan - a chain of fructose molecules linked together with one terminal glucose - and it is stored in the root the way most plants store starch. The pale taproot of a cultivated chicory can be 40 to 68 percent inulin by dry weight. That is an enormous concentration of a single class of fiber, and it explains almost everything about why chicory has mattered as much as it has.

The important thing about inulin, biochemically, is this: human digestive enzymes cannot break it apart. It passes intact through the stomach and small intestine and arrives at the large intestine still whole. There, the beneficial gut bacteria - especially the Bifidobacteria - ferment it and produce short-chain fatty acids that lower gut inflammation and support the gut lining. That mechanism is the definition of a modern class of nutrients.

1995: Gibson & Roberfroid Coin "Prebiotic"

In 1995, microbiologist Glenn Gibson and biochemist Marcel Roberfroid published a paper in the Journal of Nutrition that gave the world a new word: prebiotic. A prebiotic, they defined, is a fiber the human body cannot digest but that the beneficial gut bacteria can - so feeding it feeds them.

The founding case study for that entire definition was chicory inulin. It was not one prebiotic among many. It was the prebiotic. The word that appears today on yogurt lids, supplement jars, protein bars, and infant formula was built around the fiber inside a plant that most Americans think of as a roadside nuisance.

2018: The FDA Formally Recognizes Chicory Root Fiber

Here is the irony, sharp enough to cut. The very qualities that got chicory branded a cheap adulterant a century earlier - that it was mild, blendable, easy to grow cheaply - are the exact same qualities that make its inulin valuable now. In 2018, the US Food and Drug Administration (the descendant of Harvey Wiley's own Bureau of Chemistry) formally recognized chicory root fiber as a dietary fiber on food labels, citing peer-reviewed evidence that it improves calcium absorption and bone mineral density. The same government that once treated the root as proof of fraud now blesses it on the nutrition label.

The Extraction Industry: Orafti, Frutafit, Oliggo-Fiber

Once the science was in, the cheap root became a commodity worth fighting over - on one condition. It had to be processed. A plant growing free along the highway earns no one a profit. But wash it, dry it, chemically extract the inulin, refine it to a fine white powder, give it a trademarked name, and suddenly you have a product.

That is precisely what happened. The chicory fiber hidden in your protein bar, your gut-health supplement, or your low-sugar ice cream almost certainly comes from a small handful of European industrial suppliers - Orafti (BENEO, Belgium), Frutafit (Sensus, the Netherlands), and Oliggo-Fiber (Cargill, US). Every one of them extracts inulin from the same species: Cichorium intybus. Together they feed an inulin business worth close to $2 billion a year, and chicory is by far its single largest natural source. The cheap adulterant that once got merchants prosecuted is now the premium ingredient that gets them paid - sold back to the public in a jar for the better part of $30.

Why It Stays Buried: Harvey Wiley's 1892 Report & the 1906 Pure Food and Drug Act

Post-War Drop-Off Everywhere but New Orleans

When the Civil War finally ended and the ships returned, the rest of the country dropped chicory without a second thought. New Orleans did not, but almost everywhere else the root fell back to the roadside. That would have been survivable. Chicory could have stayed in the pantry as a wartime memory, harmless if unused. But the plant crossed the wrong side of the law before it had the chance.

1892: Harvey Wiley's Bureau of Chemistry Puts Coffee Under the Microscope

By the 1890s, the American grocery shelf had become a swamp of fakes. The federal government's chief chemist, Harvey Washington Wiley - head of the US Department of Agriculture's Bureau of Chemistry (the direct institutional ancestor of today's FDA) - was sent to clean it up.

Wiley put ground coffee under the microscope. By 1892 his bureau reported that about 87 percent of the coffee samples they tested had been cut with something cheaper. Some of what they found was harmless, like chicory. Some of it was not: sawdust, ground acorns, roasted beets, brick dust, and burnt bread. But in the public mind, chicory got filed in with the sawdust - one more thing dishonest sellers hid in your coffee to pad the weight.

June 30, 1906: The Pure Food and Drug Act

And that was not even the part that made people angry. The anger came from the label. Before June 30, 1906, a merchant could fill a tin mostly with chicory and still stamp the words "Pure Coffee" across the front, and no law could touch him. Then Congress passed the Pure Food and Drug Act - the very law that created the agency we now call the FDA.

Overnight, that tin had to tell the truth. If chicory was inside, the label had to say so. The root had done nothing but taste good and stretch a dollar. But the moment the law demanded honesty on the label, chicory became the visible evidence of a lie - the cheap thing a dishonest coffee was hiding. Its reputation as an adulterant, not the plant itself, is what pushed it out of the American cup.

Post-WWII: Instant Coffee Finishes the Job

For a while, the reputation was survivable. Then technology finished the job the law had started. After the Second World War, cheap instant coffee poured into every kitchen in America. Nescafe, Maxwell House, Folgers - now anyone could have a hot, strong cup for pennies, with no beans to grind and nothing to stretch. The one job chicory had always done, making a little coffee go further, simply stopped mattering.

So the root that two continents had once depended on slid quietly out of the American cup. It fell back to the roadside and the field edge - a tall blue-flowered plant that almost nobody could name anymore, out of fashion and out of memory, until a laboratory in Reading, England, gave it a reason to matter again.

How to Consume Chicory (Root Coffee, Salad Greens & Belgian Endive)

Chicory gives you three completely different products off the same plant - a beverage, a bitter salad green, and a forced-blanched winter head - and each one has its own harvest window.

1. Chicory Root Coffee (the classic autumn brew)

This is the drink Napoleon's France reached for, that Cafe du Monde has poured since 1862, and the reason people know the plant at all.

1. Harvest. Dig the taproots in late autumn after the first frost - that is when the plant has drawn its energy back down and the root is thickest with inulin. Wild roots run 6-15 inches deep; bring a long spade.
2. Scrub. Wash thoroughly under running water; scrub off soil with a stiff brush. Trim off the crown and any damaged tissue.
3. Chop. Cut the root into pea-sized pieces (about 1/4 inch). Smaller pieces roast more evenly and grind more easily.
4. Roast. Spread on a sheet pan and roast at 350°F / 175°C for 30-45 minutes, stirring every 10 minutes, until uniformly dark chocolate-brown and smelling like toasted nuts and caramel. Do not burn - burnt chicory is acrid.
5. Grind. Cool completely; grind in a burr or spice grinder to a medium-coarse drip-coffee texture.
6. Brew. About 1 tablespoon per 6 oz cup, brewed exactly like coffee (drip, French press, moka pot, pour-over) with just-boiled water. Steep 4-5 minutes. Strain.

The New Orleans blend: about 30% ground roasted chicory + 70% ground coffee before brewing. That is the ratio Cafe du Monde and most Louisiana kitchens use.

Start small and work up over a week or two - the inulin that feeds your gut can also make it grumble if you introduce a lot at once.

2. Chicory Salad Greens (spring bitters)

The young basal rosette leaves, picked in early spring before the flower stalk appears, make a sharp, pleasantly bitter salad green - somewhere between dandelion and endive on the bitterness scale. Uses:

• Raw in mixed salads with a sweet dressing (honey mustard, balsamic-fig, or citrus vinaigrette) to balance the bitterness.
• Blanched briefly (30-60 seconds in salted boiling water) then dressed with olive oil, garlic, and lemon - Italian cicoria all'agro.
• Sauteed with garlic and chile flakes as a bitter green side.

Older summer leaves are usually too bitter for salad - use them for tea infusion or leave them.

3. Belgian Endive & Radicchio (the cultivated cousins)

Two of the most familiar salad crops on Earth are the same species as roadside chicory: Belgian endive (Cichorium intybus var. foliosum) is chicory root chopped down after the first year and forced to sprout again in the dark, producing the pale, tight, cigar-shaped heads sold in every supermarket. Radicchio - the deep-red-and-white winter heads used in Italian cooking - is a red-leaved chicory selection. Both are grown, sold, and eaten as vegetables while the wild plant a mile down the road grows for free.

Honest Safety Notes

• Introduce inulin gradually. The prebiotic fiber that feeds your gut bacteria can also cause bloating, gas, and cramps if you go from zero to full cup overnight. Ramp up over a week or two.
• Asteraceae cross-reactivity. Chicory is in the same family as ragweed, daisy, chrysanthemum, and dandelion. If you have known allergies to those plants, introduce slowly.
• Bile-duct obstruction. Chicory stimulates bile flow (like its cousin dandelion). It is contraindicated if you have a known bile-duct obstruction or acute gallbladder inflammation.
• Do not gather from sprayed roadsides or lawn-treated edges. Most public roadside vegetation is routinely treated with herbicide.
• Chicory coffee has zero caffeine - that is a feature, not a bug. Do not expect the same wake-up jolt as coffee. What it delivers is depth of flavor, digestive support, and inulin.

How to Source Chicory (Forage, Grow & Buy)

1. Forage (the most abundant route)

Chicory grows wild across all of the continental United States, southern Canada, most of Europe, and much of the Middle East and North Africa. It thrives on the disturbed, sunny, well-drained ground almost nothing else colonizes: roadsides, gravelly lots, field edges, and old pastures.

Identification (unmistakable once you see it):

• Pale sky-blue composite flowers (occasionally white or pink), roughly the width of a quarter, scattered along stiff branching stems 2-4 feet tall. They open in the morning and close by early afternoon on hot days.
• Basal leaves resemble a coarse dandelion rosette; stem leaves clasp the stem tightly.
• Snap a stem and a milky white latex bleeds out (same as dandelion - both are Asteraceae).
• Pale, thick taproot when you dig - the whole point of the plant.

Harvest windows: young basal leaves in early spring (mildest salad greens); roots in late autumn after the first frost (highest inulin, thickest root).

Three rules:

• Only harvest from ground you know is clean - never chemically sprayed roadsides or lawn-treated edges.
• Confirm the ID before you brew - blue flower, milky sap, single unbranched taproot. Do not confuse with any yellow-composite look-alikes (those are dandelion & kin, also edible but different chemistry).
• Leave a share for the honeybees that lean heavily on chicory as a mid-summer nectar source.

2. Grow Your Own (easy in almost any soil)

Chicory is one of the easiest perennials to establish. Direct-sow seed on well-drained soil in spring or early fall, cover 1/4 inch, keep moist for 2 weeks. Full sun. Perennial in USDA zones 3-8. First-year plants build the taproot; second-year plants bolt and flower.

Choose the variety to match your goal:

• Wild-type chicory - for maximum root harvest and roasted-coffee use.
• Magdeburg / Brunswick chicory - classic European coffee-root varieties, bred for large taproots.
• Belgian endive (var. foliosum) - for the pale forced-blanched heads.
• Radicchio ('Chioggia', 'Treviso', 'Castelfranco') - for the winter red-leaved heads.
• Sugarloaf ('Pan di Zucchero') - green, cos-lettuce-shaped heads eaten as a bitter salad green.

3. Buy the Roasted Root or Blend

If you cannot forage or grow it, reputable herb suppliers and Amazon stock roasted chicory root (whole pieces or ground for coffee), fresh chicory root, and the classic Cafe du Monde coffee-and-chicory blend. What to look for on a label:

• The Latin name printed on the jar: Cichorium intybus.
• The plant part specified: root or roasted root - not just "chicory powder."
• Roast level named where possible - "medium roast" for a balanced cup, "dark roast" for the deepest color and the New-Orleans style.
• Organic or wildcrafted certification where available.
• For blends, the coffee-to-chicory ratio - the New Orleans standard is around 70/30.

Frequently Asked Questions

Is chicory coffee actually coffee? What does it taste like?

No, chicory coffee is not coffee - and that is exactly why it works. The drink is brewed from the dried and roasted taproot of Cichorium intybus, the pale-blue-flowered roadside plant. It contains zero caffeine and zero coffee bean.

Roasted low and slow until it turns dark chocolate-brown, the ground root brews into a deep, dark, nearly-black cup with a nutty, faintly toffee-like, mildly bitter flavor that reads to the palate as coffee-adjacent. Some people drink it pure. Others blend it with real coffee to stretch the beans, cut the caffeine, or deepen the flavor - the classic New Orleans blend is about 30% chicory to 70% coffee.

Because the taproot is packed with inulin - the water-soluble prebiotic fiber that made chicory famous - the brewed cup retains most of that fiber in solution, and the effect is one part beverage, one part gut-microbiome food. Cafe du Monde in New Orleans has poured coffee cut with chicory every day since 1862.

What is chicory inulin and why is it called a prebiotic?

Inulin is a water-soluble fructan fiber - a chain of fructose molecules with one terminal glucose - stored in the chicory taproot in place of starch. Human digestive enzymes cannot break it apart, so it passes intact through the stomach and small intestine into the large intestine, where the beneficial gut bacteria (mostly Bifidobacteria) ferment it and produce short-chain fatty acids that lower gut inflammation and support the gut lining.

That mechanism - a fiber that humans cannot digest but their gut bacteria can - is exactly what the word prebiotic means. The word was coined by Glenn Gibson and Marcel Roberfroid in a 1995 paper in the Journal of Nutrition, and the founding case study was chicory inulin. It was not one prebiotic among many. It was the specific fiber the definition was built around.

The FDA formally recognized chicory root fiber as a dietary fiber in 2018 (part of its post-2016 review of isolated non-digestible carbohydrates), citing evidence that it improves calcium absorption and bone mineral density. Chicory is the single largest natural source of commercial inulin - a global market worth close to $2 billion a year - and the industrial extract sold under brand names like Orafti, Frutafit, and Oliggo-Fiber comes from the same species that grows for free in the ditch.

Why did the US government treat chicory as coffee fraud?

Chicory was not treated as a fraud because it was harmful. It was treated as a fraud because the label lied.

In the late 1800s the American grocery shelf was a swamp of adulteration: coffee cut with sawdust, ground acorns, roasted beets, brick dust, and chicory. Harvey Wiley - chief chemist of the US Department of Agriculture's Bureau of Chemistry (the ancestor of today's FDA) - launched a systematic testing campaign, and by 1892 his lab reported that about 87 percent of coffee samples they analyzed had been cut with something cheaper. In the public mind, chicory got filed in with the sawdust.

Congress passed the Pure Food and Drug Act on June 30, 1906 - the same law that created the agency we now call the FDA - and overnight a tin of coffee that contained chicory could no longer be labeled "Pure Coffee." If chicory was inside, the label had to say so. The root itself had never done anything wrong - it tasted good and stretched a dollar. But the moment the law demanded honesty on the label, chicory became the visible evidence of a lie: the cheap thing a dishonest coffee was hiding. That reputation as an adulterant, not the plant itself, is what pushed chicory out of the American cup for a century.

How do you make chicory root coffee at home?

Six steps, all easy:

1. Harvest. Dig the taproots in late autumn after the first frost - that is when the plant has drawn its energy back down and the root is thickest with inulin. Wild roots run 6-15 inches deep; bring a long spade.
2. Scrub. Wash thoroughly under running water; scrub off soil. Trim off the crown and any damaged tissue.
3. Chop. Cut the root into pea-sized pieces (about 1/4 inch).
4. Roast. Spread on a sheet pan; roast at 350°F / 175°C for 30-45 minutes, stirring every 10 minutes, until uniformly dark chocolate-brown and smelling like toasted nuts and caramel. Do not burn.
5. Grind. Cool completely; grind in a burr or spice grinder to a medium-coarse drip-coffee texture.
6. Brew. About 1 tablespoon per 6 oz cup, brewed exactly like coffee (drip, French press, moka pot, or pour-over) with just-boiled water. Steep 4-5 minutes. Strain.

For the New Orleans blend, mix about 30% ground roasted chicory with 70% ground coffee before brewing. Start with a small cup and work up over a week - the inulin can make your gut grumble if you introduce a lot at once.

Where can you source chicory - forage, grow, or buy?

Three routes.

(1) Forage. Chicory grows wild across all of the continental US, southern Canada, most of Europe, and much of the Middle East and North Africa. Look for tall (2-4 foot) stiff branching stems along roadsides, gravelly lots, field edges, and old pastures, from early summer into fall. The identification signature is unmistakable: pale sky-blue composite flowers (occasionally white or pink) that close by early afternoon on hot days; basal leaves like a coarse dandelion rosette; snap a stem and milky white latex bleeds out. Dig roots in late autumn after the first frost for highest inulin.

(2) Grow. Chicory is easy to establish from seed - broadcast in spring or fall on well-drained soil in full sun, cover 1/4 inch, keep moist for 2 weeks. Perennial in USDA zones 3-8. Cultivated forcing varieties like Belgian endive (Cichorium intybus var. foliosum) and radicchio give you additional harvests off the same species.

(3) Buy. Reputable herb suppliers and Amazon stock roasted chicory root, fresh chicory root, and the classic Cafe du Monde coffee-and-chicory blend. On a label, look for the Latin name Cichorium intybus; the plant part specified (root, roasted root, or aerial parts, not just "chicory powder"); the roast level; and organic or wildcrafted certification where possible.
