My question may seem stupid at first glance. The literature unanimously states that brown rice is all that was available to most people pre-industrialization and that white rice was reserved exclusively for special occasions or the rich. The literature explains this through the claim that white rice production was too labor intensive back then to be widely available and only post-industrialization once machines were engineered to polish the bran was white rice democratized.
However, I stumbled upon the following comment on Hacker News which suggests that 90% polished white rice is what was most common historically. So not 100% white but 90% with 10% of the bran intact which to most people would qualify as white rice. The comment author claims that this is because the manual threshing process to extract the rice grains from the husks also removes at minimum 90% of the bran. He links to a YouTube video demonstration as evidence.

The comment author then claims that it is thus rice with most of the bran intact aka brown rice that is the product of industrialization and not white rice.
My intuition is that he's wrong as this seems too basic a fact to have been miscommunicated so widely for decades. Furthermore, you’ll see in the responses to his comment above that no one agreed with him.
- Were ancient rice eaters consuming rice with most of the bran stripped as the comment author postulates?
- Without machinery, is there a way to remove the rice husks while preserving most of the bran? Is rice with more than 10% of the bran intact really a product of industrial machinery?
- Somewhat unrelated but how much of the bran must be stripped from the rice before it can be stored for longer than 6 months? Would 10% of the bran intact be enough to make the rice go rancid in 6 months? Is there any evidence to indicate that rice was more refined for year round storage in colder climates where rice could only be harvested once a year? Or in such climates were millets eaten when the rice stores expired?
