Wallniture Piccola Under Cabinet Rack, 6 bottles
$6 bottles, plus a glass railBlack metal
Assessed from specification
A black metal shelf that screws to the underside of a wall cabinet, about 22 inches wide and 7 deep, holding six bottles on their side with a rail below for stemmed glasses. It turns the dead space above a counter into a small bar, which is what most buyers want it for. Reviewers say larger bottles and Champagne do not fit, and one warns the screws can come through a thin cabinet floor, so check its thickness first. It hangs high, in the warmest air of the kitchen: keep this week's bottles here, not the ones you are saving.
Not for: Bottles you are keeping. It hangs high in the kitchen, where the air is warmest, and it will not take Champagne.
