Powell & Son operates in the Barossa Valley, South Australia's premier region for bold, structured reds. The winery focuses on Shiraz and Mataro, varieties that thrive in Barossa's warm continental climate and ancient soils. The Kraehe Marananga Shiraz and Steinert Flaxman's Shiraz represent the winery's commitment to the region's signature varietal, while the Kleinig Greenock Mataro explores the darker, spicier character of this traditional Mediterranean grape. These wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, Decanter, and Falstaff. The portfolio demonstrates the depth and intensity that define Barossa Valley winemaking.
