Description of the wine Riesling Thann 2010
Most vintage, some of the last vines planted in the Rangen are declassified into either our classic Riesling or under the Thann label if the vintage is interesting, like 2010. We felt that the ‘older’ vines were slightly riper but more importantly, we feel that the root system is less deep and profound in these younger vines. The Rangen vineyard is a steep volcanic hill. The growing conditions can be tough for the vines and age matters a lot. 2010 wasn’t a drought year but some periods, especially late in season were quite dry and warm, so not all the vines behaved the same way. This wine fermented quickly and finished dry way before any other Riesling in the cellar.
Tasting notes
03/2012 : The nose shows the volcanic origin! There is plenty of flint and smoke, associated with typical stony aromas. The palate is dry but has a nice round middle touch, enhanced with some more fruity flavours. The finish is medium long and delicate. The acidity feels softer than what the numbers suggest and this is probably because of the volcanic origin that usually increases the pH. Like most Riesling, it will need some time.
The Clos Saint Urbain, Grand Cru Rangen from Thann
The Rangen de Thann is the most southerly of the Alsace vineyards. In his book « Where Alsace wines ripen », Henry Riegert writes: « from the Middle Ages those wines which ripen on the Rangen hillside figure amongst the most famous growths of the whole vineyard region ». The Grand Cru Rangen de Thann, is situated at the exit of the valley, overlooking the village of Thann with the river Thur passing at the foot of the slope.
