We have the same scenario I've been considering some basic wire styled shelves to make it look more open. Your thoughts?

We converted a built-in china hutch (and expanded) and and made a big "U" pantry by screwing 1x2s" into the wall studs, then attaching wood shelving right on top of boards, directly onto the wall. (About 12" apart). We took a big box of cereal to make sure at least one shelf was tall enough. Depending on the width for your space, we did a center "brace" top to bottom (to the ceiling) to make sure the shelves can handle the weight of canned goods. I think wall mounted shelves will give you more shelf space as opposed to the wire shelving. But, I do need a step stool for the top shelf, but I put rarely used dishes up there.

Build vertical drawers that when pulled out are open on both sides. Each one should be divided into shelves going front to back. It is a pull out pantry door. Look at Kraftmaid or Thomasville cabinets and you will see what I am describing. The door itself should also have storage shelves.

I prefer solid wood shelves in a pantry, covered with shelf liner or contact paper. Nothing gets stuck or falls thru the cracks. Easy to wipe down if something spills
