The fruit for the Polygon 5 Grenache is sourced from vines planted on deeper, more schistous soils with rivets of iron-rich clay. Biodynamic, of course. Raspberry bon bon, pepper grind, lavender and thyme, as if an expression of a unique version of Australian garrigue. The tannins, burlier here, are swabbed with tapenade as they expand with air. For comparison’s sake, this is akin to a Châteauneuf on galets, rather than one on sand. A powerful wine juxtaposed against an uncanny lightness of being.
The Polygon concept revolves around a dedicated exploration of micro plots on a certified biodynamic single site that spans some 40-odd hectares. Winemaking is done in concrete, amphora and larger format older oak barrels. Grenache is the muse. I liked the Polygon No. 3 2018 more than this wine, but each will have their fan base and they are quite distinct, despite proximity. This is a bit broader shouldered, a bit more rugged and powerful, let’s say. It hits the palate with angles, tartness, a shrill, lemon sherbetty finish, but, around that, dense, dark berry fruits, exotic spice, some rose hip tea characters, truffle and dried leaf notes. Bergamot tea tannins weave through this all, chewy, dry, a little extract and pumice-like to finish. Serious red.

Quite fragrant and attractively savory spice elements, red plums, orange zest, coal smoke and pastry-like notes. The palate has a very intense feel with ripe darker-berry flavors, in the plum and blackberry zone. The tannins are nicely zipped up and hold good shape. Striking.

After mapping and separating the Alkina vineyard in Greenock into tiny patches known as polygons, based on varying geologies, the winemaking team has made tiny amounts from the most distinctive of them in what they deem the results of intense research and extreme commitment. The prices of their Polygon wines reflect this and their rarity.
Another all-grenache wine from a small schist and ironstone section, the wine is radially different to its Polygon No. 3 sibling. Here it reveals darker fruits with herbal wildness, some orange peel and flesh also in its initial aromatic greeting. Bigger, more generous in its layered fruit power, its tannin texture is still superfine with an earth and chalk dust feel. Again, a complete statement of grape and ground.

Colonel William Light, the South Australian colony’s Surveyor-General, named the Barossa in 1837 after the site of an English victory over the French in the Spanish Peninsular War. In the mid-1800’s Silesian and English immigrants settled in the area. The Barossa itself comprises two distinct sub-regions: Eden Valley and the warmer Barossa Valley floor at 270m.The Barossa Valley enjoys a warm Mediterranean climate characterised by hot dry summers and relatively low rainfall. Cool sea breezes from the Gulf of St Vincent modify the temperature, however hot northerly winds can occasionally dominate creating considerable vine stress. Many older established vineyards are dry-grown, but supplementary irrigation is also extensively used. The valley is comprised of rich brown soils and alluvial sands. A long history of uninterrupted viticulture in the area means the Barossa valley is home to Australia’s largest concentration of old-vine Shiraz, Grenache and Mourvedre with many over 100 years old. Although most famous for Shiraz, the Barossa can also produce fragrant and deliciously fruity Grenache blends and beautifully rich, chocolatey Cabernet Sauvignons.
