I have homebrewed before. Beer can be fun to craft.
basically homebrewing is personal small scale beer  production
Yes, that is correct. And it can be used to make some really cool concoctions.
beer has been brewed by home brewers even prior to commercial production
Home brewers have been around for centuries if not thousands of years.
when people first started they made thick beers, then fruit and rice wines
That's interest. Rice is also very versatile.
woman were the main home brewers before beer was even commercialized
