The 2021 Descendant is often termed as the "Baby Runrig," which, as we all know, is a bit of a myopic way to view things, but it gets the point across. This is Shiraz fermented on Viognier skins (8% by weight, no liquid) and decidedly floral on the nose, with marmalade and orange peel, pink peppercorns and blood plums. The wine is dense and velvety, with loads of tannin; the Viognier, while contributing floral aromatics, textural silk and flow, also contributes tannin, and it is felt here. There is no new oak, which helps with the tannin expression and core of red and purple fruit. The signature Barossan red dirt and ironstone show through the finish. It's really good! Excellent wine. 15% alcohol, sealed under cork and wax.

The superbly pitched 2021 Descendant has it all. Significantly elegant, it displays a concentrated core of tar, granite and black chocolate lifted by finer, spicy, meaty, dried rosemary nuances. Great upfront power, well composed before opening to a fine and detailed style, punctuated by al-dente tannins. Delicious and will build handsomely in bottle.

Winemaking
The Descendant is sourced from the Descendant Vineyard, where Shiraz vines are grown from cuttings from RunRig vineyards and interplanted with rows of Viognier. The Shiraz is co-fermented with Viognier skins, intensifying aromatic lift and tannin integration. Fermentation takes place in open-top fermenters with extended maceration, followed by basket pressing. The wine is matured in second-use French oak barriques for 20 months, previously used for RunRig. Bottled unfined and unfiltered, Descendant displays floral lift, plush fruit, and refined structure, mirroring a Northern Rhône-style approach.
