Will Shields

Winemaker

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.
