Not true. Grapefruit character is something I've observed in several of my
Chardonnays during their youth. It goes away with age. Don't worry.

Your bigger problem is "extremely tart". It might have been a mistake to
inhibit ML in this wine. OTOH, if the pH is really low, ML may never have
gone anyway. You may need to address this issue with potassium carbonate if
the wine is too acidic to be enjoyable, but you don't have to do that until
just before cold stabilization. Be sure to do bench trials first.
