Buy shallow bins for the highest shelf and it's fine for all of them if you like. You'll never lose a bottle to the far corners again. If there's a frame and you'd like to use as much of the shelf as possible buy 2 bins per shelf and make good and sure the width of both bins is width of shelf minus one frame width or you won't be able to get out the bins!

On the bottom shelf lots of ways to go. I'd love get something like this. Lots of people love turntables. They work well unless you have an outer ring of bottles and an inner ring.
