Default Strong grapefruit like smell on chardonnay.

Thanks Tom,Clyde and KJ for the responses. I'm going to keep an eye on
it. Could the grapefruit smell "possibly" be oxidation like KJ said or
is that NOT possible? I know what aceldhyde smells like and it doesn't
smell like that BUT I have only smelled it in red wine. Does it smell
different in white? I just want to do all I can to diagnose this. I've
read that PVPP might help if it is. Does anyone have any experiences
with that stuff???

TIA
