Thanks for the tips everyone! I'll be soaking my caps as I use them...the oxygen barrier will hopefully hold on. If I notice problems with my brew, I'll look at that aspect as a factor first.

This is fine... if you don't mind wasting extra money on the oxygen caps. The oxygen absorbing compound is activated by getting it wet. When you sanitize them, they are (theoretically) pulling in some oxygen from the environment, but not from within your bottles. This is why you are supposed to cap them dry, turn them over, and then set them back on their bottoms. Wetting the cap is what activates the oxygen absorption.

If you are bottle conditioning, then the yeast will almost certainly use up any oxygen left in the neck of the bottle. If you bottle off of a keg, as I do, you may want to invest in the better caps and, if you do, don't sanitize them.

Given the fact that your caps are going on a sanitized bottle that is now filled with an antibiotic, alcohol rich substance, there is very little reason (other than paranoia) to sanitize your bottle caps, even if they are the "plain" ones.

Hmm maybe I won't then...I've got a lot to learn! And decide on. I guess some of it is personal preference, but if the people who don't sanitize the caps aren't having an issue, it seems as if it is in fact an extra step
