Absolutely not. I've only got roughly a years experience, but have plenty of resources to share. Much like growing mushrooms. It's amazingly easy so long as you keep things sanitary. It really is pretty much juice, sugar and yeast (over simplified). There are finer touches like yeast nutrients and energizer, but still not difficult to understand. People used to ferment in unsealed clay vessels. With the world falling apart, at least knowing the basics of fermenting will be a valuable skill. Which is why I finally took the plunge to learn this past year. I've found I really enjoy it and it's applications go far beyond simply alcohol for consumption.
