This spring, I applied to the Canadian national seed bank and obtained an Einkorn wheat sample along with some others.
It didn't grow so well, and I think it was because I planted it in an area that was too wet, and too nutrient rich. I harvested about double the amount I started with so next year I'll plant it somewhere else.
It's a very beautiful grass I must say. It's very low yielding wheat compared to modern strains, and the husk is much more difficult to remove. This means that it's a big job to process, hence the high cost of the flour.
It's basically a pioneer species and as such, it thrives in dry areas with poor soil.
The grain we see growing in the Sepp videos I'm pretty sure is Russian rye. There is a
video online where his son takes the camera for a tour. He talks about the crop specifically for about 5 mins, and he states that they plant it in the spring, cut it back for animal fodder during the summer and then harvest it for the grain in the second year. This causes the grass
roots to mature properly, and the grain harvest as a result is more than if they harvested every year, plus they get a fodder crop as well.
From what I understand, wheat wont survive two years like this. It's an annual grass that dies every fall on it's own.
