In vino, veritas.

Our kitchen/dining room is a bit small for a free-standing wine rack, which means that we have bottles taking up precious room in the cupboards.

However, we do have an empty narrow wall behind the dining room door that I reckon could easily take a slim wall-hung rack like this one from Vintage View.

Think I'd mount it a bit higher than it's shown here, though. I can just imagine Himself's niece or nephew wrapping an eye socket around those empty low-level hooks!
