So, I'm in a process of planning for the next year competitions. In fact, I'm little bit behind since I'm planning to do big brews (few meads and beers).
I already had a similar thread about packaging entries using different types of corks, even though I've got my answer I've got more questions.
So, most of the competitions require 12oz bottles with crown cap. There are few exceptions, like Mazer Cup (mead competition). For them you should enter the product in appropriate package (like sparkling mead or 2-3 year old mead should be packaged in appropriate to style bottles).
So, my question is... How should I prevent my homebrew (beer/mead/cider) from oxidation over time in regular 12oz bottles with crown cork if waxing is not authorized? Is there some sort of shrink-sleeve that I could get specifically for beer bottles (and remove it before sending to competitions)?
