While we are on our search for economical ways to store wine, it doesn't get much simpler than this. A few holes drilled out in just the right size and you're all set.
A riddling rack is a cool way to store wine (and just a cool addition to a space, even if the temperature's not right for actual wine storage). And they always look great propped up.
This is my favorite piece ever. I love the antique french riddlers rack. I found one I wanted so badly but it didn't make sense financially and in a rental apt. I dream to have one someday.
