I suspect there’s some differentiator going on behind the scenes. I remember those wooden paddle “spoons” having a distinctive wooden flavour, and there was some fast food chain that brought wooden spoons a couple years ago: the first ones were obnoxiously “wood tasting” but the current ones seem to have no flavour at all.

Note: none of these were bamboo, they were all some type of lighter tree wood

Edit: if you’re not sure on the taste we’re talking about, chew on a wooden toothpick until it goes a bit soggy: same flavour.

I think it was more of a dry feeling on the tongue and palate than an actual flavor, kind of like a tongue depressor. At any rate, it was a weird experience for someone who grew up using stainless steel.
