Will Shields


Sevenhill Cellars opened a new winemaking chapter in January 2019 with the appointment of Will Shields. Will has more than 25 years’ experience as a winemaker, with major stints in Western Australia’s Margaret River region and New Zealand. His love of wine was sparked from his upbringing in the Hunter Valley where his parents owned Oakvale Vines. Will studied at South Australia’s Roseworthy College, before earning his stripes in WA, receiving a string of accolades – as many as 50 awards – during his time at Vasse Felix and Clairault. After nearly four years in New Zealand at The Wine Portfolio, Will returned to Australia in 2016, joining Kirrihill Wines in the Clare Valley. Allowing fruit to express itself is at the heart of Will’s approach to winemaking, using a soft hand to achieve balanced, elegant wines.

Matt Green

QLD Sales Manager

Matt brings 40 years experience in the hospitality industry in QLD, engaged in both on and off premise channels and working with family owned and independent hotels. Prior to coming to Sevenhill he spent 7 years representing the Samuel Smith & Sons portfolio with a vast range of brands including Yalumba, Vasse Felix, Wirra Wirra, Brokenwood and many others.

A self-described “wine nerd”, the history and amazing wines of Sevenhill and the story behind the brand has inspired him to represent them in the QLD market. Spending the last 3 years working in the premium wine market with the Sense of Taste brand for Star Liquor, he has seen a lot of wine and believes Sevenhill is possibly The Clare Valley’s (if not Australia’s) best kept wine secret!
