Description of the wine Riesling Clos Häuserer 2005
The Clos Häuserer vineyard is located on the bottom of the Grand Cru Hengst in Wintzenheim, on a rich, deep, marl limestone soil. Planting Riesling in this Clos was a little bit a gamble for my father. Usually, Riesling prefers lighter, stonier, rocky soils that allow better ripeness and burn more the malic acidity. Riesling is also a fertile and vigorous grape variety, planting it in a rich soil can bring higher yields. Well, perhaps my father resented a climate change in 1973, the year this vineyard was planted, because today Riesling is perfectly adapted to this vineyard. (In fact, the Institut de la Recherche Agronomique in Colmar dates precisely a change in the climate in 1973 in Alsace. The climate is getting warmer of 0.06°C every year since that date). Like most other Riesling, this one fermented a full year.
Tasting notes
01/2007 : The Clos Hauserer 2005 develops a rich intense mineral nose. The grapes were harvested at very high level of ripeness, with a small presence of noble rot, which is not obvious on the nose, but explodes on the palate. Like most other wines in 2005, the sweetness is quite hard to detect on the nose but palatable on the finish. The high acidity gives a sensation of freshness and delicacy. A long lived wine !
The Clos Häuserer of Wintzenheim
This soil rich in clay and chalk gives an important structure to the Riesling grown in the Clos Haüserer. Although this vineyard benefits from a warm and precocious climate, ripeness is achieved much later than the surrounding terroirs.
