Alder is a very popular wood choice for unfinished kitchen cabinet doors. As long as the stain is not too dark, this wood finishes beautifully. Alder does not evolve in color or darken when exposed to light or heat as other woods do, and takes stains and finishes well. This material offers a cost-effective alternative for those doing a DIY remodel project on their kitchen cabinets. Alder cabinet doors and alder glass panel doors also offer some variety in the grain of the cabinet doors without a lot of contrast.
