Matthew Deller MW is one of the most respected figures in Australian wine today. With a global career that spans New Zealand, the United States, and now Australia, Matthew has consistently held leadership roles that blend a passion for fine wine with sharp business acumen. Currently, he serves as CEO of Wirra Wirra and Ashton Hills—an exciting, focused portfolio with bold ambitions to elevate its premium reputation.

Matthew’s path reflects a rare balance: the depth of a Master of Wine and the strategic mindset of a global executive. From senior positions at Constellation Brands to his active involvement with the McLaren Vale Grape Wine and Tourism Association, Matthew has made it his mission to strengthen not only the brands he leads but the regions they represent.

It was clear from our conversation that Matthew doesn’t just love wine—he loves the industry that brings it to our tables. We spent over an hour talking through his journey, his leadership philosophy, and his vision for South Australia’s wine future.

A huge thanks to Matthew for joining me.
