Quick Answer: Ancient wheat varieties are older grain types that often grow taller, need fewer inputs, and handle drought better than modern commercial wheat. The poulard wheat Italian farmer Claudio Grossi found in his attic is one example. Its trade-offs are real, though: the tall stalks can fall over in storms, yields are lower, and the dough can rise poorly, so growing it well takes planning.
Sometime in the early 1990s, Claudio Grossi, a 40-year-old farmer near Parma, Italy, cleaned out his attic and found a sack of seeds he couldn't identify. He shook them onto a manure pile and forgot about them. Within a season, one type of wheat was growing six feet tall, with seven ears on a single stalk instead of one. That's where the story of ancient wheat varieties starts, and it's also a warning about how fragile our modern grain supply may be.
What Grossi Actually Found in the Attic
The sack had probably been left by Grossi's great-grandfather, who started the farmstead around 1915. The seeds were dry, cracked, and so old that Grossi doubted anything would sprout. Several types did. One stood out. Its plants were roughly twice the height of commercial wheat, and each stalk produced seven ears in a fixed pattern: one long ear surrounded by six shorter ones.
The kernels were bigger than average, too. They came in yellow, black, red, white, and even green, sometimes on the same stem. Grossi had farmed grain his whole life and had never seen anything like it. He couldn't find it in any agricultural reference he owned.
Then he remembered the Book of Genesis, where Joseph interprets a dream about "seven ears of grain came up upon one stalk." Grossi, a practicing Catholic, saw the match. Whether or not the biblical passage describes the same plant, the link pushed him to ask the question that drove the rest of his work: if people farmed this wheat in ancient times, why doesn't anyone grow it now?
Why Modern Wheat Got Shorter
Wheat has been cultivated for about 10,000 years, starting in the Fertile Crescent. Early varieties were much taller than today's, and they competed well with other grasses. Over the centuries, farmers favored strains that produced more grain, and taller plants lost out.
The shift accelerated in the early 20th century. By the early 1920s, Italy was still recovering from World War I and importing roughly a third of its wheat. After Benito Mussolini became prime minister in 1922, his government pushed "elite" high-yield varieties through a campaign called la Battaglia del Grano, the Battle of Wheat. Around the same time, U.S. farmers faced the Dust Bowl, when exhausted Great Plains soils blew away.
The mid-century Green Revolution, led by American agronomist Norman Borlaug, pushed selective breeding even further. The new semi-dwarf wheats produced far more grain. They also had trade-offs. Shorter plants often couldn't outcompete weeds, and they were more vulnerable to disease. Growers responded with herbicides, fungicides, and synthetic fertilizer.
Here's the part most histories skip. Those inputs weakened soil over time, which made the crops less resilient to the very climate stress they were meant to survive. Modern wheat became more productive on good years and more fragile on bad ones.
The Bread Problem Nobody Warned Grossi About
Growing the grain was only half the job. Grossi's first loaves rose poorly. They'd swell, then collapse. In the early 2000s, he started working with an older local baker who still kneaded by hand and refused modern machines.
Together they tested a few ideas. They let the dough rise in smaller batches, and they proofed it in taller wicker baskets that helped the shape hold. Their biggest finding was that less kneading improved the leavening. The baker's dough held its structure, and the loaves had a nutty, sweet flavor that Grossi said he couldn't find in commercial flour.
The practical lesson is that ancient varieties often need a different process, not just a different seed. Heavy mechanical mixing that works for high-gluten modern flour can overwork a dough made from lower-gluten grain. Reduce mixing time, use smaller batches, and watch the dough, not the clock.
What the Lab Tests Actually Showed
A University of Parma food science student, Beniamino Perobelli, tasted the bread at a farmers market and made it the subject of his undergraduate thesis. Working with the lab of professor Teofilo Vamerali, he identified the grain as Triticum turgidum, known in English as poulard wheat. Its name comes from the Latin for "swollen," and it originally evolved in what is now Turkey, Egypt, and nearby Mediterranean countries.
Perobelli's analysis found several differences from modern wheat. The grain was richer in phosphorus and iron. It contained less gluten than modern wheat, and it had more lysine, tryptophan, and arginine, amino acids that matter for protein building blocks and growth.
These are real findings, but they come from a thesis-scale comparison, not a large clinical trial. Don't read "less gluten" as "gluten-free." Poulard wheat still contains gluten, and anyone with celiac disease needs to avoid it. Treat the nutrition claims as promising leads that deserve replication, not settled science.
Perobelli later told Smithsonian that the mineral richness and higher non-gluten protein content were "very pleasant surprises." That kind of surprise is worth noting, because it shows how little this crop has been studied.
Ancient vs. Modern Wheat: Where Each One Wins
Ancient varieties aren't a straight upgrade. The useful question is which crop fits which conditions. Here's how grano del miracolo compares with a typical commercial wheat, based on Grossi's observations and the Parma analysis:
| Trait | Grano del miracolo (poulard) | Typical commercial wheat |
|---|---|---|
| Plant height | About 6 ft (roughly twice commercial height) | About 3 ft, per Grossi's comparison |
| Ears per stalk | 7 (one long, six shorter) | 1 |
| Fertilizer and herbicide needs | Grossi reports none used on his farm | Routinely applied in intensive systems |
| Gluten content | Lower, per Parma analysis | Higher |
| Main weakness | Lodging (stems fall in wind, rain, hail) | Less drought tolerance, input-dependent |
The table shows the trade-off clearly. The tall plant beats weeds and drought, but it flattens easily. Grossi solved this by interplanting miracolo with shorter wheat that gives it structural support. That's a practical fix you can apply yourself, and it's a better answer than simply "plant the old stuff."
Here's the counter-intuitive part. Most articles frame ancient grains as a straight nutritional win. In practice, lower yields raise the cost per tonne, and a farmer can't feed a market on a crop that flattens in the first storm. The real case for ancient wheat is risk reduction, not higher output.
Why Diversity Is the Real Insurance Policy
Francesco Sottile, a biodiversity researcher at the University of Palermo, argues that relying on a small number of wheat cultivars is a systemic risk. Prolonged droughts, extreme heat, and pests or diseases that evolve resistance to chemical controls can all wipe out a narrow crop base.
Sottile pointed to Sicily, where 2024 brought what he called one of the worst droughts in 35 to 40 years. Many commercial wheat growers abandoned their fields in April because they could see they wouldn't harvest what they had sown. Smaller farms growing heritage grains fared better. As Sottile put it, most of the farmers adopting ancient grains were able to collect and harvest.
The lesson isn't that every farm should switch to ancient wheat. It's that diversity spreads the risk. When one variety fails, another may still stand. This next part matters more than it looks: a diverse set of varieties is only useful if farmers actually grow them and buy them.
How to Start Growing Heritage Wheat Without Synthetic Fertilizer
If you want to try heritage wheat, don't start with an attic seed. Grossi's story is remarkable precisely because it was lucky. Germination in very old seed is unreliable, and it may carry disease. A safer path looks like this:
- Source certified seed. Buy from a reputable heritage seed bank or organic seed supplier, and ask for germination rates and disease-testing information.
- Run a germination test first. Sprout a sample of seeds on damp paper towels before committing a field, so you know what percentage will grow.
- Plant in a mixed stand. Pair the tall variety with a shorter, stiffer cultivar. This reduces lodging, the failure mode that wrecked Mussolini-era tall varieties and still troubles growers today.
- Reduce or skip synthetic nitrogen. Start with a soil test and build fertility with compost and rotation. Expect to adjust the approach over several seasons.
- Budget for lower yields. Plan for less grain than your commercial benchmark, and price the crop for a niche buyer if you can.
- Find a miller and a baker before harvest. Grossi's crop found its market through Molino Grassi, a local organic miller, and the flour reached artisanal bakers in Italy and abroad.
Before you commit land, check a few things:
- Confirm the variety's exact species name, such as Triticum turgidum, so you can compare trials and seed catalogs.
- Ask whether your region's extension service has trial data for heritage wheat.
- Check local rules on seed sourcing and disease testing.
- Test a small plot first. A 10-square-metre trial costs little and shows you lodging, yield, and disease pressure in your own conditions.
Frequently Asked Questions
What are ancient wheat varieties?
Ancient wheat varieties are older grain types, such as einkorn, emmer, and poulard wheat, that were cultivated before intensive breeding. They are generally taller, have less uniform ripening, and need fewer synthetic inputs. They usually yield less than modern commercial wheat, which is the main trade-off for growers.
How do I grow ancient wheat without fertilizer?
Start with a soil test, then build fertility through compost, crop rotation, and legume cover crops. Expect lower yields in the first seasons. Grossi reports growing his heritage wheat without fertilizer or herbicides, but his soil conditions and climate are specific to his farm, so test before you copy the approach.
Why does ancient wheat fall over so easily?
Tall ancient wheats have long, thin stems that bend under heavy wind, rain, or hail. This is called lodging. Before the grain ripens, a flattened crop can rot or be harder to harvest. Growers often plant tall varieties alongside shorter, stiffer ones to provide structural support.
Is ancient wheat healthier than modern wheat?
It's too early to say for sure. A Parma University thesis found poulard wheat had less gluten and higher levels of some minerals and amino acids than modern wheat. Those results are promising, but they come from a limited study. Less gluten doesn't mean gluten-free, so people with celiac disease should avoid it.
Start Small, Track the Results, and Share What You Learn
Ancient wheat varieties aren't a miracle fix for climate stress, and Grossi would be the first to say so. Their real value is diversity: a second crop that can survive when the main one fails. If you farm or bake, try a small test plot or a single loaf made with a heritage flour this season, and note the lodging, yield, and rise. Pass this to someone wrestling with weather losses or weak dough, and let the results make the case.
