I take apart my bottling bucket spigot, clean it, and re-install it. Then I fill my bottling bucket with 1 gallon of more water than I have beer to bottle. Next, I add the scaled amount of Star San to the water in the bottling bucket and stir it all up. Then I start filling my bottles with the Star San solution to sanitize them. Lastly, I dump the Star San out, fill the bottle with beer, and cap em' with a sanitized cap.
It takes me a while, but I don't have a bottling tree or vinerator yet.
