2001 Ch lafaurie-peyraguey (sauternes 13.5%)
from half-bottle; 90% Semillon, 5% sav blanc, 5% muscadelle. Quite an advanced dark gold colour; waxy, “skinsy”, smoky oak and nuts over ripe apricots, lemons some bitterness present, and another example from an excellent year for sweet wines.
Drink to 2022; score 91
2005 Ch Doisy-daene (barsac 14%)
From half-bottle; 95% Semillon, 170 g/l rs. Lighter colour, lighter elegant style; barley sugar, prominent acidity, passionfruit and orange blossom. Amazingly, seems not as sweet as the L-P, but all in balance. More time will be rewarding.
Drink to 2025, score 92+
2010 Ch Roumieu
A producer I haven’t tasted before – these two wines were served blind.
Bright light pale straw colour, syrupy sweet, tropical fruit, stonefruits and pineapple, with an overlay of green nettles, almost a celery. Tightly wound with abundant cleansing acidity.
Drink now-2025, score 90
1970 Ch Roumieu
Colour suggests the wine is clearly older, and exudes some petroleum and light toffee characters. Some waxiness on the palate and there is still fruit and acid, but slimmed down. While this wine has seen better days, the contrast is quite enjoyable. Seems about 25 years older.
Unmasked, same company but 40! years older. I’m amazed at this.
Drink now, score 87 (I have not added any points for surprise at its drinkability at such an age)
