This 1980 from Graham's has received very good reviews, both from professional and amateur tasters. When I opened a half bottle last year, I was impressed but suspected the bottle might have been slightly corked. So I opened another bottle this Christmas, and the result was the same: great flavor profile but a damp cardboard aroma that is similar to that of a corked wine. Two others at the table detected these same scents; others found nothing not to like.
Although 1980 is not considered on a par with great vintages such as 1990, the wine is youthful and pleasant. Ripe blackcurrant, glides down easily and is a good match for Bouche de Noel. But still that troubling damp cardboard smell. Oh well, just enjoy the wine.
