The grapes come from the Barossa, in South Australia and the Eden Valley. Situated at a latitude of 34° South, the Barossa region is made up of rolling hills and valley floors. The growing season often sees hot, warm weather with temperatures of 35°C, which can result in vine stress, helping to concentrate the flavors in the berries. The wide diurnal temperature differences help to retain balancing acidity. Some of the grapes come from Berton's original vineyard in the Eden Valley, where the climate is cooler. The vine age is varied, but all vines have been spur-pruned and are generally trained on a
single-wire cordon trellising system. The soil styles in the vineyards are varied, ranging from clay to limestone and sandy soils, with each terroir adding its characteristics.
