John,
So I'm looking at this impressive build, and I started thinking (now you know you are in for it). Are you going to hang the robotic arm to pluck those bottles out of the rack, put them in your robotic cart, which will properly chill the whites and slightly cool the reds to the recommended temperature, then deliver it to you anywhere in the house (or yard)?
You could also program it to clean your bottles for you.
On a more serious note, how is the cooling system keeping up with the heat and humidity that looks like it isn't letting up anytime soon (at least not before October or so)?
