Cienna

Cienna (sih-en-nah) is one of three new varieties of wine grape varieties developed by CSIRO and granted Plant Breeders Rights in 2000. Cienna, Rubienne and Tyrian are all progeny of a cross between the Spanish variety Sumoll and Cabernet Sauvignon, made in 1972 by the late Allan Antcliff at the Merbein research station. Each of the new varieties was selected using criteria including good (grape juice) sugar:acid ratios, low pH, good colour and flavour and adequate yields.The aim was to produce highquality red varieties suited to Australian conditions.The best few varieties were extensively trialled and evaluated by industry panels and under a range of climatic and cultural conditions.
