Aldehyde?

[Lurker]

A friend and amateur wine judge said that aldehyde had an effect on wine taste. He said that it is one of the gases that escape when you decant before drinking. Does anyone know anything about aldehyde? It sounds like something that we may want to eliminate from our wines. :B

I think it has to do with yeast strains, O2, and SO2 levels.

Here is a link below on some info pertaining to this:
