2023 Polygon 22 Grenache, Alkina

The Polygons are the tiny distinct plots identified by terroir expert Pedro Parra at Alkina’s biodynamically certified vineyard in Greenock, Barossa. Polygon 22 is a small trip of 220 younger bush vines, planted on contours of fractured schist and a small (but powerful) amount of limestone. Pedro claims to have only encountered this combination of soils twice in his career mapping many great vineyards of the world. There’s a subtle lifted red petal note and savoury edge here, with a core of transparent, succulent darker berry fruit. The grapes are hand harvested, and the entire ferment was whole-bunch, spending 26 days on skins before basket pressing. It was matured in a single 700 litre concrete egg.
