Marcello Casella, son of the Casella Wines founder, will front Sydney District Court over drug charges on Friday.
Marcello Casella, Andre Turner and Francesco Polimeni are scheduled to appear before the court for a readiness hearing.
They were charged in 2014 after police discovered 2750 cannabis plants with an estimated street value of $5 million on a Crowther property.
Readiness hearings are held to determine whether a case is ready to go to trial.
Mr Casella rose to prominence with his brothers, transforming Yellow Tail Wines into one of Australia's major wine exporters
He parted ways with the company in 2014.
In 2014, the company distanced themselves from Mr Casella in a statement.
"Mr Marcello Casella resigned as a director of Casella Family Brands earlier this year and therefore this matter is entirely unrelated to the company or any of its associated brands," the statement said.
