I vote for all in your head. I've been drinking craft beers, and macro beers for 25+ Years and been brewing for several of them, and a well crafted beer, is a well crafted beer, regardless of whether it was made by you, a macrobrewy a craft brewery or the local brew pub. Granted even commercial beer can be infected, or suffer from dirty lines......But that's going to be the minority, rather than the majority.
I think what you're having is what's often called a "Pink Cloud" experience. This is all new, and everything homebrewing is bright and shiny, and your (excuse the metaphor) poop doesn't stink (or in this case your yeast farts
). And I think eventually the "high" will mellow, and things will be more "real." And you'll have a more down to earth perspective on things. This is common to anything...You've heard about it in religion I'm sure, or even quitting smoking....the new convert is often the most annoying, because they've gone from one extreme to the other, but eventually they'll swing back to the middle. You'll start to taste well crafted and excellent beers other than homebrew once again, and maybe even realize that some of yours and other people's homewbrew can often taste like crap too.
