Ruffino Chanti Classico

[cglass2602]

I have recently acquired a bottle of Ruffino Chaianti Classico Riserva Ducale 1967 and I am curious as to the history, flavor characteristics and value of the wine. I am by no means a connoisseur by definition, but I certainly appreciate the bouquet and palate a fine wine can provide. Any items of interest you can provide would be welcomed as I am unsure as to whether to indulge or add this specimen to my collection as a potential investment.
Thank You,
