In my opinion, a shower only amplifies the quality of the beer (and vice versa) if you just finished some hard yard work on a hot day, or something to that effect. Then it's a nice treat. In all other circumstances, I don't want shower water in my beer.

i’m trying to imagine a shower lacroix, or something that’d be my equivalent, and i can see how that would be nice after sweating. bonus for lacroix is that it already tastes like shower water

I do not drink LaCroix and you are not selling me on it
