types of wood that can be used in a humidor?

[the nub]

very prudent post, Shilala. I think most people overestimate the positive flavor enhancement of Spanish Cedar. I for one can't stand it. Keep in mind the Cuban cabs will impart a different aroma then what you would get with the solid SC that you would get from a supplier. A lot of people might not detect the difference and if you are one of those, then maybe it's not that much of a concern.

I've had good success with solid birch in my stand-up humi and a friend has lined his walk-in with Russian Birch, which is used in cold food display case. I can say that after nearly a decade, the birch has a neutral effect and is extremely stable in that environment- as a closed small volume box, YMMV.

Finally, I've had very, very favorable results in aging loose sticks in a solid mahogany lined desktop. Overall, that would be my number one choice. Keep in mind I'm not a cabinet builder, only basing my opinion on medium term (10+ years) storage experience.
