Torbreck: vineyard cuttings, co-fermentation, barrel reuse
A producer in Barossa Valley handling Shiraz and Viognier. Descendant, which is linked to vineyards used for RunRig, is a red wine in which Shiraz and Viognier skins are co-fermented.
Explain the link between Descendant and RunRig by matching each to viticulture, fermentation, and maturation stages, one by one.

Vineyard planted in 1994
The Descendant vineyard is said to have been planted in 1994 using cuttings taken from the vineyard used for RunRig. Even though the plant material is inherited from older vines, it does not mean the age of the vines themselves equals that of the original vineyard.
Co-fermentation of white varieties with skins
The Shiraz is added on top of the Viognier skins that have been lightly pressed for use in RunRig, and they are fermented together. This process is different from simply blending red and white at the final stage. Both the grape combination and the timing of bringing the two together are important.
Continuity extended even to barrels
Aged in reused French oak barrels previously used for RunRig. There are three connections: cuttings, Viognier skins, and barrels, each representing different stages—cultivation, fermentation, and maturation. You cannot simply explain it as dividing the same brand’s ingredients.

What does 1994 indicate?
The Descendant vineyard is said to have been planted in 1994 using cuttings taken from the vineyard used for RunRig. Even though the plant material is inherited from older vines, it does not mean the age of the vines themselves equals that of the original vineyard.
Viognier skin
The Shiraz is added on top of the Viognier skins that have been lightly pressed for use in RunRig, and they are fermented together. This process is different from simply blending red and white at the final stage. Both the grape combination and the timing of bringing the two together are important.
What are the aging barrels?
Aged in reused French oak barrels previously used for RunRig. There are three connections: cuttings, Viognier skins, and barrels, each representing different stages—cultivation, fermentation, and maturation. You cannot simply explain it as dividing the same brand’s ingredients.

Explain in your own words
Explain the link between Descendant and RunRig by matching each to viticulture, fermentation, and maturation stages, one by one.
Check after writing
- Did you associate each label with its region and grape variety?
- Did you separate the shared and differing conditions in your comparison?
- Did you clearly indicate the year(s) the material covers or the date checked?
