I just need a lil advice...

[Caberenee]

I found several wine bottles in my mother's cabinet...much to my surprise, she was never a wine drinker. Anyway, I was wondering if these two bottles were from good vineyards or if they were even good. The first is a Merlot del Piave from La Villa Veneta from 1993. The other is a Mouton-Cadet Bordeaux from 1983. I just need a lil advisory as to whether i should save these or crack them open for a special occasion.
