I may not make too many friends in the kitchen design field, but the kitchen is one of the last places I would consider for storage of fine wines, except perhaps for the very near term. 

I have seen open storage built-in above stoves and grills, next to dishwashers, and in the direct line of afternoon sunlight.  Heat, vibration, and light are all present in varying degrees within most kitchens, making them among my least desirable locations for a collection.

There are a number of quality under the counter units available, and there is something to be said for the convenience of having access to wine in the kitchen. Regardless, in-kitchen storage would, for the reasons I have specified, not be my first choice for anything except short term storage of ordinary consumables.
