The GSM contains the three most important old varieties of the Barossa, creating a magical blend where the whole is greater than the sum of its parts. The Grenache components are sourced from up to nine different old bush-vine vineyards across the Barossa Valley and then matured in large old foudre. The Shiraz component is from the Eden Valley giving structure & dried herb aroma and the Mataro is sourced from a 60yo block in Nuriootpa on sandy soils for spice and tannin. - Winemaker note
