Alkina is a Barossa project with an unusual backstory: a historic Greenock property (vines dating to the 1950s) bought in 2015 by Argentine vintner Alejandro Bulgheroni, then handed to South Australian winemaker Amelia Nolan, who worked with terroir specialists to map the site's soils block by block. The estate is certified organic and biodynamic, and Grenache is very much the star here - limestone and schist soils give red and dark berry fruit, chalky tannins and real freshness, made with minimal oak so the site can do the talking.
