Phil Lehmann and Jonathon Hesketh run the Lehmann Hesketh venture. This project honours their fathers, Robert and Peter, who previously partnered and hold massive roles in the history of South Australian wine.
The label combines Barossa Shiraz with Coonawarra Cabernet. Bottlings released by the partnership include the 2013 Lehmann Hesketh Mk 01 Cabernet Shiraz as well as the 2016 Lehmann Hesketh MK 03 Coonawarra Barossa Cabernet Sauvignon.
