Diamond Bins?

[hotwine]

I built several out of 1"X12" pine several years ago, sized so each bin held a case (think they were about 14" square), but found two problems with them: they were inefficient for storing less than a case in each bin (and mixing wines in a single bin confused my tiny brain); and they didn't allow air circulation around the bottles to maintain consistent temp and RH. Use racks of welded stainless steel rods from Sam's now, and they're working pretty well (except for the instability of fat bottles when double-stacked).
