Oh, and as far as bottling: if you're bottling off of a keg, it can be really easy to be inconsistent in terms of oxygen exposure. It's a surprisingly difficult process at home.
I use a fully-sealing counterpressure filler, I blast the bottle with a ton of CO2 before switching over to the liquid side, I cap on foam as quickly as I physically can after filling. And I still try to fill the day I'm dropping them off, the day before at the absolute earliest.
As for the caps: yeah, technically you are supposed to use gold or silver caps. The reason being, it is theoretically possible to recognize the beer by the cap and the category. There used to be a judge who always used blue caps, and always entered imperial stouts, which were always amazing. You *knew* whose beer you were judging, because of the cap.
But, no points are lost, bottle inspection is merely a comment.
