*Collectibles* Incredibly fresh and vibrant, this stunning Champagne weaves a tightly knit skein of ripe pear and tangy yellow plum fruit flavors together, with accents of rich pastry cream, toasted brioche, elderflower, ground cardamom and coffee liqueur. Shows a beautiful texture. A thread of salinity winds through to the lasting finish. Disgorged fall 2013. Drink now through 2029. (12/2014)

The 2003 Clos du Mesnil is insanely beautiful. Vivid, resonant and textured in the glass, the 2003 boasts magnificent depth and pure breed. Since I last tasted it a few months ago, the 2003 has begun to shut down, which is probably a great sign for its future and overall longevity. Hints of smoke, slate and dried pear gradually open up in the glass, but the 2003 mostly stands out for its exceptional finesse. 94+ (AG) (11/2014)
2003 was especially difficult in Mesnil, because the frost in early April halved the crop. 8,671 bottles and 659 magnums were made. Harvested 27 and 29 August. Really impressive nose -- very broad, creamy, and flinty, with a little bit of reductiveness combining with a smoky flavour and a lovely dairy yoghurt character. Dry and savoury, fabulous length and intensity on the palate. The reputation of this cuvée is deserved in the sense of the sheer quality of flavours and the massive depth on display. It doesn’t seem clumsy in the way that some 2003s do --but it isn’t doesn't have the defining acidity of, say, Salon 2002. In fact it is quite soft. The real attraction, though, is the range and power of the nose. 18.5/20 points. (RH) (7/2014)
Krug Clos du Mesnil, a very rare Champagne, showcases the unique character of a single plot of Chardonnay, harvested in a single year. Our 1.84-hectare vineyard overlooked by the village church has been protected by walls since 1698. The vineyard is located in the heart of Mesnil-sur-Oger, one of the most iconic villages for Chardonnay in the Champagne region. Krug Clos du Mesnil has an expansive generous personality enhanced by the finish which powers through with extreme precision.
2003 stands out for its dramatic climate of extremes: a very dry winter and spring with an early flowering period followed by a very warm summer. The rare beauty and singularity of the year’s grapes are expressed by the power and aromas inherited from the very particular circumstances of 2003, making this year an exceptional one.
The House of Krug chose to create Krug Clos du Mesnil 2003 because, from the very first tastings, the Chardonnay grapes of the 2003 harvest already revealed a delightful, expressive and balanced character without any excess aromatic intensity.
