I can only locate one professional tasting note on the 1976 Gruaud Larose:-
“Concentrated, leafy, green tea nose, with a black truffle note and a hint of cassis. Firm, spicy, ripe fruit and medium body. An elegant very stylish ’76.–Gruaud-Larose vertical”.
The Wine Spectator. (February 1991).
The two most recent tasting notes on the 1976 Gruaud Larose on Cellartracker:-
“Still a deep color. Warm, earthy, sage nose. Showing its age in the taste, but still elegant and long”.
“Chris brought this. The label was pretty battered, but the cork said 1976. The year I graduated High School (and half the people at the tasting had not been born yet). I had low expectations for this. Not a horrible vintage but not great and I thought this likely to be DOA despite that Gruaud Larose made very long lived wines back then. I was wrong. The cork broke on opening but came out in two pieces. It was not decanted which might have been a good thing (especially since I got an early pour). Deep ruby in color. The nose had a touch of funk, but some cassis with tobacco, both cigar and smoked. On the palate, there is most definitely fruit. Cranberries and cassis. Not a whole lot of layering and complexity which surprised me yet it had vibrant fruit. At 41 years, that’s not bad. A fun treat. Thanks Chris”.
