I'm not sure on the science, but I'd think a half full barrel will result in lots of air touching the whiskey, which can cause it to lose flavor. With a full barrel, almost no air touches the whiskey.

I've never used barrel wax and never had a leakage problem. Maybe as the barrels get older it will be a problem, but by then the char will probably be minuscule, so I'll just replace them.
I drop the cleaning tablets in when I am first soaking the barrel, then again if I go too long between batches and keep it filled with water.

Question for those that do this.
Love me some whiskey. If I bought the 10L, is it as effective if it isn't filled up when aging? Or would you really need to place 5 handles at a time in there?

My best results have been with vattings of multiple bourbons, such as the OWA/W12. The barrel seems to help the various flavors mingle in an agreeable fashion.
I also tried it with flavored rum, and that turned out very well. I threw some vanilla beans into a bottle of cheap rum for about a month, added a little orange peel for a couple hours. I strained that into the barrel, and aged it for another month. The time in the barrel really seemed to bring the flavors together, and added a nice touch of oak.
I have rye in the barrel now, for my own Angels Envy rye knockoff.
