When thicknessing the back on my current build, I noticed some yellow discoloring starting to appear in the sapwood. Does anyone know what it is and how long it takes before it disappears? The white-balance is a bit off on the pic, but the stuff has a really intense, lemonish yellow color. You can see it on the cut-off on the pic, but not on the actual back. Thanks!

Character

I like little things like that that show its a natural material. As long as it dosnt affect the stability of the wood. Someone may have a better answer.

It's wood. I like the inconsistencies as long as there are no structural concerns, which it doesn't appear to be in your case.

Sondre, I couldn't say for sure if this color is a stain from something the tree sucked up and is permanent or not. It isn't uncommon for wood that is not completely dry to exhibit a yellowish color until it dries. Could this stuff be a bit green still?

Nothing wrong with character . It's just that the color is so intense it looks completely unnatural. And it looks bad around the center seam since the stuff appears to have occurred at random...

The set has been drying in my shop for at least a year now. I guess I'll just wait and see.... Thanks guys

Staining in sapwood is quite common. As long as there is no decay, it should be fine structurally. If you don't like the appearance, you can always dye it.
