Despite seemingly indicative synonyms or morphological She may not share similarities with the varieties Courbu Blanc. Noah. Riesling or Sémillon be confused.

The exact origin is most likely the French Pyrenees near the Spanish border, where it was first mentioned in 1783. The noisy name derives from the crisp character of the berry peel. The medium maturing vine is very prone to real mildew, It provides neutral white wines with aging potential. But it is also called table grape used. In France, the vine is almost extinct and occupied less than one hectare in 2010. In the Spanish Basque country (País Vasco) it is grown with the varieties Courbu Blanc and Noah and all three are called Hondarribi Zuri (see Hondarribi Beltza ).
The variety came to Australia around the year 1850 under the name Sales Blanc, where they were sold in the Barossa Valley and Clare Valley was widely cultivated. For a long time she was confused with Sémillon. Because you mistakenly as Riesling referred to, she got the name Clare Riesling after the Clare Valley. It was only in 1976 that the French ampelographer Paul Truel (* 1924) clarified the true identity. In the Clare Valley, she has now been replaced by the real Riesling. Today she is mainly in the fields Murray Darling and Swanhill (New South Wales), as well Riverland (South Australia) cultivated and occupied here 95 hectares.
After South Africa Crouchen came under the name Groenblaarsteen (Grünblatt Steen) already in 1656 and was here referred to as Cape Riesling, Paarl Riesling and South African Riesling. The real Riesling followed shortly thereafter in 1664. It was not until the 1950s that Christiaan Johannes Orffer (1926-2008) found that various varieties were cultivated under the name Riesling in South Africa. Since the vintage 2009, Crouchen may now no longer be used in Germany as Riesling. The variety is mainly in the two areas Breedekloof and Paarl grown. The South African stocks are 629 hectares. In 2010, a total of 725 hectares of vineyards were reported (Statistics Kym Anderson ).
