2016 & before
2011
I grew wheat in all three terraces, mowed it, raked it by hand, and then threshed and winnowed it, as documented in these videos.
Harvesting wheat in 2011

After threshing
After threshing and winnowing, I couldn't find a seed separator, but ended up reading about people in New Mexico "washing the wheat", and by pouring water over it, I succeeded in floating off all the bindweed seeds, and then I quickly drained the wheat and dried it in the sun. After that, I borrowed a friend's flour mill, and used some sieves to make more flour than I was able to use in a year! The chickens ended up eating a bunch of the older wheat. Fun project; I learned a ton.
