It didn't make sense? Are you sure? or are you just being uncharitable on HN? How do you think alcohol was discovered? How about any fermented food? Do you think someone drank 3 day old juice because they wanted to? Or leftover cabbage from the party this weekend?

Do you know what Kombucha is? What lactobactre, and yeast are? You've never accidentally fermented anything? You don't have kids or your life isn't hectic, you've never imbibed ethanol?
