Alkina was established in 2015 when Argentinian vintner Alejandro Bulgheroni purchased a 60-hectare farm near Greenock in the North Western corner of Barossa Valley. 

With 70-year-old vine and 170-year-old stone buildings in need of repair. Amelia Nolan was tasked with bringing new life into the old bones of the farm. With the guidance of acclaimed winemaker Alberto Antonini, terroir expert Pedro Parra and a strong local team, Alkina is now a magical place with terroir winegrowing and regenerative farming at its heart.

Polygon No. 5 consists of two very similar nearby parcels making up 0.37 hectares in size. It is significant for its heavily fractured schist that contains clay and iron in the fractures. With a slightly thicker band of topsoil, there is more clay influence here, but once you get more than four feet down the schist becomes quite dense. Southern Cross certified organic and biodynamic.

1700kg of fruit was handpicked on the 15th of March from Polygon No. 5. Just like P3, we left 80% as whole bunches in the ferment as always in Nicol Velo unlined concrete tulip. With a cool, natural ferment and gentle extraction, it was pressed after nearly a month on skins before malolactic fermentation. The wine was matured in a 1200L concrete tulip for 10 months and bottled in February 2024.

The vintage shown in the picture is different from the one we're currently offering. 

Winemaker Notes

Polygon No. 5 has thrived in this cool year, presenting a darker, brooding nose of crushed rock, red and dark berries and a wild, amaro-inflected spice profile. Opens up slowly and magnificently in the glass, revealing blood orange, pomegranate and dark berry notes on the palate. There’s real presence here – with a silhouette that fills the doorway – and a tannin profile that is perhaps even more integrated at this young stage than in years previous. Energy, tension and a real sense of subtlety in 2023. Akina
