Penna Lane operates in Clare Valley, South Australia's premier cool-climate region within the Mount Lofty Ranges. The winery's Watervale Riesling has earned recognition from Wine Enthusiast, Decanter, Wine Advocate, Wine Spectator, and Falstaff. Clare Valley's elevation and diurnal temperature swing favour aromatic white varieties and structured reds; Penna Lane's portfolio reflects this terroir through Riesling, Cabernet Sauvignon, and Shiraz. The Watervale Riesling, sourced from the region's signature subregion, demonstrates the mineral precision and stone-fruit character that define Clare's finest expressions. Cabernet Sauvignon and Shiraz complete the range, offering the depth and complexity expected from South Australia's premium wine country.
