Shiraz (Vivier)

Shiraz (Vivier) refers to a specific clone or selection of the Syrah grape varietal. It is not a separate grape variety but a particular type of Syrah known for its specific characteristics and performance in certain growing regions.

The "Vivier" designation indicates that the clone originates from, or is associated with, the Vivier nursery or selection program. This program likely identified and propagated Syrah vines that exhibited desirable traits such as specific fruit characteristics, disease resistance, or yield potential.

Using clonal selection is a common practice in viticulture to improve the quality and consistency of grape production. Different clones of the same grape variety can express varying characteristics in terms of aroma, flavor, tannin structure, and growth habits. The Vivier clone of Shiraz/Syrah is likely chosen for its particular expression of these traits.

The use of the "Shiraz" name, rather than "Syrah," is common in Australia, South Africa, and parts of North America, although both names refer to the same grape variety. The naming convention often reflects stylistic differences in winemaking, with "Shiraz" often associated with richer, more fruit-forward styles, whereas "Syrah" might indicate a more restrained, savory approach. However, this is not a strict rule.

Therefore, "Shiraz (Vivier)" signifies a specific clone of the Syrah grape, typically chosen for its unique attributes and characteristics as developed and propagated by the Vivier selection program. The name is commonly used to refer to this clone when planted and used in winemaking, especially in regions where the term "Shiraz" is preferred.
