At the heart of Stonier lies a meticulous approach to viticulture and winemaking. Stonier sources Chardonnay from over 150 acres across five sub regions, Merricks North and Balnarring, Tuerong, Red Hill and from the estate vineyards at Merricks which span over fifty acres. Early morning processing of the hand harvested Chardonnay blocks is essential, air conditioning in the barrel room means that temperatures are kept under control. Fermented predominately in a selection of new and seasoned French oak barriques, treated to an occasional lees stirring and malolactic. To maintain the lovely fresh Stonier style, a component is tank vinified without malolactic to preserve natural acid crispness.
