The straws are longer, which is why they cannot be fertilized with nitrogen. Unlike other spelt varieties, it was never crossed with wheat. It was also not bred for dough stability, which is why it must be baked in a special way, for example, using a water roux. The glutenin-to-gliadin ratio is different, resulting in a highly extensible but weaker gluten network.

It is really different from usual spelt, which was crossed with wheat and has shorter straws.

Edit: maybe this is interesting to some so I'll write a short paragraph about older varieties. There is also Einkorn and Emmer. Einkorn is considered the ultimate ancestor of all modern wheat varieties. It has been grown 10k years ago and is diploid with only two chromosome sets. Then there is Emmer, which is also ancient and appeared shortly after Einkorn. It is tetraploid and yields two corns per spikelet. If you want to eat like an Egyptian Pharao you can eat bread made out of Emmer ;-)

Rye is entirely different. It is very hardy and frost resistant and can't be baked without sourdough because of the amylase.

No, Einkorn is not the ancestor of all cultivated wheat varieties, unless you extend the history of wheat a very long time before domestication, when that becomes somewhat true, because the wild ancestor of emmer wheat was produced by genome duplication from a wild ancestor of einkorn wheat.

At the start of the Neolithic, besides barley, 2 species of wheat were domesticated separately and they evolved through domestication into einkorn wheat and emmer wheat.

Einkorn wheat has always remained a minor crop, while either barley or emmer was the major crop, depending on soil and climate. For instance in the early Ancient Greece barley was the most important, while in the early Roman Republic emmer was the more important. Later, emmer ("far" in Latin) was mostly replaced by durum wheat ("triticum" in Latin), and even later durum wheat was mostly replaced by the hexaploid bread wheat ("siligo" in Latin).

Besides the original emmer and einkorn, other wheat subspecies have appeared many thousands of years later after domestication, either through mutations, like the tetraploid durum wheat (pasta wheat) or through hybridization, like the hexaploid bread wheat (and also the hexaploid spelt wheat).

Why is that? I thought nitrogen is taken in through the roots, then distributed as other ground-based nutrition, regardless of the height.

But what is the actual benefit of Urdinkel? Honestly it sounds a bit like a fad to me, along the lines of "older = better".

So the second two but not the first is technically "wheat" along with Rye ?

I tried both Emmer and Einkorn, but don't remember anything special about the end result. One of the flours/doughs was pretty yellow, but that's about it. It was a while ago and I only tried about a kg of each so my memory is fuzzy.
