Maglieri Wines founder Serafino (Steve) Maglieri acquired the 'McLarens on the Lake' property in 1998. The site contains 120ha of shiraz, Cabernet Sauvignon, Chardonnay, Merlot, Semillon, Barbera, Nebbiolo, Sangiovese, and Grenache. Part of the grape harvest is sold and the best material is reserved for the Serafino label.

Steve was crowned ‘Bushing King’ for best red wine in the McLaren Vale Wine Show in 1979 – an honour he achieved again in 1992 and 2007. Numerous awards have followed including the Trophy for Best Shiraz and Red Wine of the Year at the London International Wine Challenge in 1997 and earning the Trophy for the most consistent Shiraz at the London International Wine Challenge after winning Gold in its class for five consecutive years.
