In one of the pictures you can see a wire rack. Presumably that's for stuff that doesn't fit in the horizontal racks.Sick...so I guess you don't age stuff that isn't Lambic or c&c? I mean, you wouldn't store BCBS bombers and the like in that manner, right?
P.S. you're one handy sonofabitch...I could've done the tile but that's where my expertise ends. Really awesome.
Also, capped stuff can go in those racks just fine as long as it's the right shape. I stored Bruery bottles in something like that for years without issue.
