Tasting note
Barossa Valley Shiraz should give the 2020 Grand Barossa a bold aroma of blackberry, plum and cracked pepper, with a warm savory tone. Expect a full, generous palate, firm tannins lending structure while fresh acidity keeps the dark fruit from seeming heavy. Peak maturity is through 2035, and the window stretches to 2041; a long finish should hold pepper, berry and a gentle earthy note.
