This is a popular 3rd Growth from Margaux appellation. Decent value especially in average vintages. This 2009 was highly rated. Hence, the higher price. :)
'Aromas of blueberries, blackberries and flowers. Very beautiful. Full body, with a solid core of fruit and firm tannins. Balanced and refined. This is ultra-refined. Best wine from here since 1970! One of the great values of the vintage.' James Suckling 95 pts.
'Silky and rich, this showcases black cherry with gourmet touches and swirls of black pepper and rosemary. There's certainly an exotic edge here, with the natural drawing in of its Médoc tannins and highly enjoyable mouthwatering finish. It's a good Giscours with clear personality, focus and balance. Decant if drinking it in the next five years.' Jane Anson, Decanter 94 pts (2/2019)
'The 2009 Giscours has a generous and complex bouquet with well defined blackberry, cedar, mocha and light ferrous notes, more like a Saint-Julien than Margaux. The palate is medium-bodied with fine tannin, fresh and vibrant with curry leaf and graphite. A dash of white pepper pops up towards the finish. This is a very fine Giscours to enjoy over the next 15 to 20 years.' Neal Martin, Vinous 93 pts (3/2019)
