JR, I have those same looking metal racks, where did you get the little sides? Your setup is real nice and clean, but one problem, your empty carboys are TOUCHING each other, I know you jiggle that rack everytime you move something around and those empties tink each other and before you know it the bottom falls out of one when its full of wine! You really need to put some kind of padding between them to keep them from tinking against each other. Also, a simple papertowel wadded up and stuck into the end keeps out dust and vermin while allowing them to breath. We used the extra shelves from the racks to make one for standing bottles, it holds a heck of alot more than a regular wine rack. WVMJ
