After seeing plenty of discussion about the benefits of waxing vs wasting time, I decided to test it myself. In 2010 I got some KBS. I waxed some and left the others as is. The past 2 nights it was time to find out which, if either, aged better. Well, the waxed bottle was much better. The coffee flavor was much more prominent and the bourbon was much better. All-in-all, the waxed bottle was simply better. Granted this was only a couple bottles, but both came to me at the same time, were from the same batch, and were stored identically. This may not always be the case, but waxing is easy and if it gives me a better beer, I'm gonna do it more.
