There is one theory that humans first used grain grasses such as wheat and barley as fermented drinks rather than as bread.

Some civilisations didn't have alcohol at all till recently.

Aborigines in Aussie & Native Americans to name 2.

That's why they struggle with alcohol now, not having been inured to it for generations like other civilisations.
