The variety: 'White Cabernet Sauvignon' syn Shalistin 

The South Australian grape variety 'Shalistin' is making a name for itself on the international wine scene. As the only white variety of cabernet sauvignon, it is unique.

Its developers, Malcolm Cleggett and Anne McLennan of Cleggett Wines, found the original bunches of grapes more than 30 years ago. They took two cuttings and propagated them. A dozen vines were grown from the original propagation, and Cleggett now oversees two hectares of the variety.

Shalistin has also been invaluable as a scientific research specimen. After studying Cleggett's grape varieties for many years, the CSIRO has published a paper detailing the gene change of red grapes to white, revealing how white grapes have developed over the past 2000 years.

The company: Cleggett Wines

Cleggett Wines began in 2000 with just two grape varieties and has become an international name in viticulture. Shalistin, one of the few new Australian grape varieties being commercially produced, has further enhanced their standing.

The value of PBR

Because Shalistin is so rare, Cleggett has been able to license the variety to other growers to cultivate, and looks forward to royalties increasing as the new grape becomes more popular.

The company can do this because the PBR system gives it commercial rights over the new variety for 25 years.
