Established in 1972, Mountadam Vineyards was founded by the late David Wynn. Wynn is without question one of the most significant contributors to the Australian Wine Industry. Wynn was the first to recognise the potential of a cool, elevated site to produce Australian wines of great elegance and structure. He named the vineyard after his son, Adam who in 1984 became the company winemaker. Wynns search for a vineyard site which met his expectations took him across Australia. He settled on an area high above the township of Eden Valley in the sub-region now known as High Eden. High Eden was recognised as a sub-region of Eden Valley in 2001. It is an oval shaped area of 40 square kilometres of the highest areas of Eden Valley.
In 2005, David and Jenni Brown purchased Mountadam Vineyards from then owners LMVH. In late 2015 the Browns acquired the second, High Eden vineyard established by Wynn (as part of the Wynns group which would later become part of Treasury Wine Estates). The two vineyards are dissected by High Eden road. The Brown family are keen to continue Wynns vision to produce wines of elegance and structure. A focus on sustainable low input viticulture will guarantee the success of the vineyards into the future. Current head winemaker is Phil Lehmann who was appointed in December 2019. Phil brings a wealth of experience with him and under his guidance things look well set for the future.
