Wine Racks... varnished or unvarnished

[hotwine]

When I used wooden racks in the form of plywood diamond cubes, I refrained from varnishing for fear of tainting the wines. Now use racks of welded steel rods, so it's no longer an issue. But if I still used wood, would probably prefer redwood or western red cedar, neither of which requires varnishing (they do, however, both exhibit an odor that might penetrate the capsules and corks to the wines, over time).
