Celebrated Stroud winemaker Helen Gillard relies on nature as much as technique to produce her vintage.
She has no doubt the underground water systems that run across the Gloucester Valley are an essential factor in her vineyard's success.
That's why she will be joining Sunday's coal seam gas national day of action.
"My concerns are fairly typical of anyone with a bit of insight," Ms Gillard, who established Mill Creek Vineyard in 1997, said.
"Until we have some real knowledge about what is going to happen with the aquifers, particularly in this valley where the geological formation is so interconnected, we shouldn't be tampering with things."
The Gloucester Valley, which is already under pressure from coalmining, has become a touchstone for community concerns about the rapidly expanding coal seam gas industry.
The latest exploration licence data indicates more than 100 wells could be drilled between Gloucester and Stratford over the next decade.
Ms Gillard said she had little faith in government assurances that the industry would be tightly regulated and monitored.
"It think it's rubbish because all of the monitoring is carried out by people who are beholden to their employer. That's been our experience with mining noise monitoring," she said.
