Tahbilk is one of Australia's oldest family-owned wineries, established in 1860 in the Nagambie Lakes region of Victoria. The winery remains owned and operated by the Purbrick family, now in its fifth generation, producing wines including Marsanne (for which it is particularly renowned), Shiraz, and Cabernet Sauvignon. As an independent, family-owned producer with a strong focus on sustainability and heritage winemaking, it offers transparency for consumers seeking alternatives to corporate wine conglomerates.
