Everyone agrees that wine bottles should lay down for long term storage so that the corks don't dry out and spoil the contents but there are different ways to store flat! Bottle racks that pullout are pretty and functional but an expensive solution. Small cubes are great when you have all different vintages. If you buy by the case though, the biggest bang for your buck are x-boxes that keep all the bottles together. A successful wine room utilizes all of these solutions to make organizing as cost effective and efficient as possible.
