is this wine any good??

[jwatson]

Hi everyone,

Going through my grandmother's house and came across a 3 bottle box of robert mondavi wine. They are:
1978 Fume Blanc
1975 Cabernet Sauvignon
1977 Napa Gamay

The box has been sitting upright in the back of a closet for lord knows how many years....
Can anyone give me any info on this wine and if it would be any good?

Thanks!
Joe
