Yes it does. Fish sauce contains fermented fish and still tastes umami
but don't make me elaborate. Maybe that's because my bottle of worcestershire is 2 years past expiration date but I can taste only something like balsamic vinegar and some hot spices.
Well, I've never tasted perique that tasted of "umami". Fruity, sure (Figs, raisins, dark fruits, etc). Spicy, yes. Has a bit of a pressure-type (maybe like white pepper) situation going on in the nose when you retro it, that too.
Vinegar, hmmm, are you sure the blend wasn't cased with a vinegar recipe? For example, Rouxgaroux, has a bit of a vinegar tin note to it, but I'm pretty sure that the casing and not the perique. And it doesn't really come through for me when I smoke it (same for McClelland's, the vinegar/ketchup doesn't come through when lit).
Now, if you were to tell me that you're getting umami notes from something like Kentucky or Lat, then I'd probably be more inclined to understand.
But palates are different for everyone so that's fine too.
