The medium maturing vine is very susceptible to real ones mildew, It produces 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 Spanish Basque country (País Vasco) it is grown with the varieties Courbu Blanc and Noah and all three are called Hondarribi Zuri (see below Hondarribi Beltza ).
The variety came to Australia under the name Sales Blanc around 1850, where it was grown in Barossa Valley and Clare Valley was grown over a wide area. For a long time she was mistaken for Sémillon. Since you mistakenly call this Riesling designated, it got the name Clare Riesling after the Clare Valley. It was not until 1976 that the French ampelographer Paul Truel (* 1924) clarified the true identity. In the Clare Valley, it has now been replaced by the real Riesling. Today it is mainly used in the fields Murray Darling and Swanhill (New South Wales), as well Riverland (South Australia) grown and occupies 95 hectares here.
To South Africa Crouchen already came under the name Groenblaarsteen (green leaf steen) in 1656 and was referred to here as Cape Riesling, Paarl Riesling and South African Riesling. The real Riesling followed shortly afterwards in 1664. It was only in the 1950s that Christiaan Johannes Orffer (1926-2008) found that different varieties were cultivated under the name Riesling in South Africa. Since 2009, the term Riesling can no longer be used for crouchen domestically. The variety is mainly used in the two areas Breedekloof and Paarl grown. The South African stocks amount to 629 hectares. In 2010 a total of 725 hectares of vineyards were reported (Statistics Kym Anderson ).
