Glaetzer is a winery in the Barossa Valley, South Australia's most celebrated red wine region. The vineyard produces Shiraz of remarkable depth—its flagship Shiraz earned a 98.0 average rating from prestige critics including Wine Spectator, Wine Advocate, Decanter, and Wine Enthusiast. The Amon-Ra Shiraz, a secondary expression, follows at 93.8. Beyond Shiraz, Glaetzer crafts a Cabernet Sauvignon–Malbec blend rated 93.1 on average.
