Former Canterbury Bankstown Bulldog Peter Mortimer, his wife Julie and their five sons, Michael, James, Tim, Daniel and Robbie planted Chestnut Garth Vineyard to 1 hectare of Chardonnay grapes in 1996.
The following year a further 1.2 hectares of Shiraz and 1 hectare of Cabernet Sauvignon were added. More recently a small area of Pinot Noir and Merlot was planted. They source Sauvignon Blanc from a neighbouring vineyard.
Chestnut Garth vineyard is named after a quiet avenue in the rural Humberside village of Burton Pidsea in the UK where Peter played Rugby League for Hull Kingston Rovers in 1987. The original street sign is "on loan" and adorns the entrance to Chestnut Garth Vineyard at 786 Burrendong Way Orange in New South Wales.
