Heidi Schrock, Zweigelt, Burgenland 2018: This Zweigelt Rusterberg is dark red in colour with aromas of black cherry and hints of cocoa. Austrian winegrowers often refer to Zweigelt as ‘the fighter’ due to its hardy nature; however, Heidi’s Rusterberg has an elegant core, silky tannins and a lot of character. Alc 13% Grapes: Zweigelt
