Rapeseed, 3rd part

When I returned to check on the rapeseed it was gone. The farmer had done his harvest.

I did find couple of straws on the side of the road and this is how the seeds look like when ready for harvest:

I cannot imagine how many of these tiny seeds you need to get one litre of rapeseed oil. I would have loved to find out and to continue the story about how the cold pressed rapeseed oil is made, but unfortunately my story about the rapeseed field ends here.
And as I mentioned before I only use cold pressed rapeseed oil, I never heat it and I store it in the fridge.
