Warburn Estate was officially established in 1968 by Giuseppe and Tony Sergi, a farsighted father and son team of Italian descent.   Giuseppe Sergi was born in Reggio Calabria, Italy on 13 February 1910. At the age of 19, Giuseppe joined the army as a Basalieri for 18 months. At the age of 23, Giuseppe married Maria Sergi on 10 November 1934. In 1935, Giuseppe and Maria had their first and only son, Tony. After World War II commenced, he was recalled to serve his country and fought in the battles for 2 years and after his fourth child was released from duties. In 1952, Giuseppe and his family decided to move to Australia due to the traumatic post war conditions. In 1954, the family moved to Farm 1305 Tharbogang.

By the end of 1998, the Company was awarded 363 medals and 10 trophies in only 4 years of entering the wine show circuit.  In 2000, the Company invested a further $21 million in winery and vineyards. These investments have enhanced wine quality, enabled Warburn Estate to process increased quantities of grapes, meet the increasing export demand for Australian wines and achieve greater economies of scale in production.

The Company’s extraordinary range of styles and consumer price points in its portfolio now includes brands such as 1164 Family Reserve, Warburn, Lombard Station, Three Corners, Kanga's Leap, Bushman’s Gully and Gossips.

Further, in May 2003 a $5.5 million bottling line capable of producing up to 10,000 bottles of wine an hour was opened. The totally automated bottling line is part of a four-acre complex that also houses receiving and dispatch facilities, a laboratory and extensive temperature-controlled warehouses for product storage.
