Richard Buller operates in Victoria, Australia, where warm continental conditions and diverse terroirs support both classic Bordeaux varieties and the region's signature Shiraz. The winery's portfolio centers on structured reds: Cally Premium Selection Red, a Cabernet Sauvignon–Merlot–Petit Verdot blend that balances power with complexity; Cally Shiraz, which expresses the varietal's dark fruit and spice; and Tawny Barrel Aged, a fortified expression aged in wood. Wine Spectator, Wine Enthusiast, and Wine Advocate have assessed the range, with the Cally Premium Selection Red and Cally Shiraz earning particular recognition. The winery's focus on barrel-aged and blended formats reflects a commitment to depth and aging potential.
