The loaf in your hand is a late machine. Egypt, the Alps and the first farmers ate wheats that still wore their hulls.
What you’ll learn
- The loaf that is not this wheatSeparate modern bread wheat and durum from the three hulled species, and treat farro as a shop name rather than a Latin one.About ninety-five percent of wheat production is free-threshing bread wheat. Einkorn, emmer and spelt are hulled crops, not wild grasses, and Italian farro is usually emmer.
- A grass that waited to be harvestedConnect brittle rachis, Fertile Crescent domestication, and the order einkorn, emmer, hexaploid wheat.Domestication kept the ear intact. Einkorn and emmer were hulled staples of the Neolithic package. Hexaploid wheat is a later hybrid with goatgrass.
- Einkorn, one grain on the earIdentify einkorn as diploid AA wheat, place Heun's Karacadağ result, and read Ötzi's last meal as hulled cereal plus fat and game.Einkorn is the first cultivated wheat. Genetics point to Karacadağ. Ötzi ate it 5,300 years ago. Its dough is weak because glutenin is low, not because gluten is absent.
- Emmer, the wheat that fed EgyptName emmer as hulled tetraploid AABB, the staple of pharaonic bread and beer, and durum as its free-threshing cousin.Egypt baked and brewed emmer. Tomb bread and the Meketre model record that kitchen. Let the hull go and the same genome becomes durum.
- Spelt, hulled and hexaploidTreat spelt as hulled AABBDD wheat, explain the D-genome cross, and separate European Dinkel history from primitive myth.Spelt is not an ancestor of bread wheat. It is a hulled hexaploid. Goatgrass donated D. German fields dropped it when white bread won, then bought it back.
- The hull is the taxExplain dehulling, the Q and tenacious-glume genes, and why yield and lodging pushed hulled wheats off the main field.Hulled wheat needs a second harvest. Q and Tg decide whether the glumes let go. Yields of thirty to sixty-seven percent of bread wheat are the price of keeping the old lock.
- What the bag still will not tell youRead a farro or spelt label, reject the gluten-free myth, and leave the open question of non-coeliac tolerability.Shop names hide species. Hulled wheats still contain gluten. Whether any of them is gentler for non-coeliac wheat sensitivity is not settled, because most comparisons were not grown side by side.
Questions this course answers
About how much of the world's wheat harvest is common bread wheat, according to the FAOSTAT figures Geisslitz and Scherf report for 2016?
Geisslitz and Scherf report that about 95 percent of wheat produced is common wheat and about 5 percent is durum. Einkorn, emmer and spelt are minor.
Put these wheat stages in the order they appeared
Einkorn first, then emmer, then the D-genome cross that made hexaploids, then European spelt as a hulled hexaploid crop. Bread wheat's free-threshing form is a later use of that same hexaploid stack.
Match each wheat to the genome set it actually carries
Ploidy counts the genome copies. Hull is a separate trait. Spelt and bread wheat share AABBDD; only the glumes divide them.
What does the German name einkorn literally mark on the ear?
Ein Korn is one grain. Emmer spikelets usually hold two. The name is anatomy, not marketing.
About how many years ago did Ötzi die, the Alpine mummy whose last meal included einkorn?
Maixner and colleagues describe the Iceman as a 5,300-year-old European glacier mummy. His stomach still held einkorn with ibex, red deer and a great deal of fat.
Why did most pharaonic Egyptian bread stay low, according to Muhs?
Muhs writes that most pharaonic bread was emmer wheat, which has less gluten than modern bread wheat and consequently does not rise much. The low loaf is the flour, not a failed bake.
