Eli5: how is it possible that a wooden barrel, which is used for aging alcohol, does not rot away.

Question

Or how do they prevent it from rotting for such a long period of time.

I cant imagine that they use multiple wooden barrels during an aging proces of 30 years or so. Because it would interupt the proces, I geuss?

Answer 1

Alcohol kills any bacteria that would eat away at the barrel. Also barrels aren normally treated for it and air tight, not allowing foreign substance to be introduced.
