I don't understand how it takes people so long to clean and sanitize bottles. I clean homebrew bottles as I go (aka rinse thoroughly) and dry on bottle tree. Now I have over 200 bottles cleaned and upside down in cases. On bottling day I quickly dunk them in a starsan bucket and hang on the tree, and start filling when I've hit 48 or so. It takes almost no time. I definitely think having a clear process helps, and I find it rewarding.
