From a tasting of Noval Colhieta from 1937 to 1986 in the Noval shop in VNG on 30 Sep 07 - see review here
My less than comprehensive note says "Not much nose - lacking complexity".
I placed this 6th out of the 7 tasted and recall there being a significant gap in quality between this and the 5th placed 1974.
