Back to the OP and original topic...
I myself have puristic tendencies. I believe many homebrewers, myself included, have had a tendency to meddle too much, without very well determining whether our additional efforts are really adding anything positive to the bottom line, which, of course, is beer flavor and quality.
Also take into consideration that many brewers make fantastic beer the easy way and don't fart around. They just come up with a reasonable recipe, brew it, and enjoy it.
So I am with you. I'm interested in getting back to basics, and not sweating details too much. Crush well, mash well, mash in the right pH range, clean fermenters well, ferment well with healthy yeast. That....... that is about it.
Cheers all.
