Nice work, Dean! Excellent advice. I wish someone had told me all that stuff 25 years ago. Maybe they did, and I just didn't listen.
Some brewers are cooks. Some brewers are chemists. Some brewers are engineers. ALL brewers are janitors.
The only meaningful things I'd add at this point are:
1. A utility sink makes your life much easier.
2. Even for extract beers, I think you should be boiling in stainless, not aluminum.
3. Personally, I think a bottle-capper is a reasonably good investment compared to trying to find many Grolsch (flip-top) bottles, especially given your propensity toward 22oz and 750ml bottle consumption.
4. Dark and big beers hide more homebrewing sins than small, pale beers. Ironically, one of the most difficult styles for a homebrewer to replicate is American macro lager.
5. Re-read ALL that stuff Dean took the time to write.
6. Rather than starting all by yourself, find a club and go brew with someone. It's more fun and you'll learn a lot.
A very good homebrew shop is FH Steinbart
in Portland, OR. Their website isn't very pretty, but they do have a nice selection.
I haven't brewed in about ten years, but I still have too much stuff in the garage. I guess I'm rationalizing that I'll want to do it again some day. Peter, I'll set you up if you take a road trip to Washington.
