Surrounded by the sea on three sides, Margaret River enjoys a strong maritime climate very similar to Pomerol and St Emillion in France, in a dry vintage. So it’s little wonder the Cabernet Sauvignon is so damn good.
Additionally, the low diurnal and seasonal temperature range results in an unusually even accrual of warmth. In temperature terms, the overall climate is similar to that of the French regions of Pomerol and St. Emillion in a dry vintage, so it’s no wonder the quality of its Cabernet Sauvignon, Merlot and Chardonnay is so good.
The physiographic characteristics of the region provide a degree of protection from winds blowing in from the ocean. The principal soil type is predominantly gravelly or gritty sandy loam that has formed directly from the underlying granite and ancient bedrock.
The soils are highly absorbent when moist but moisture quickly flows from sloping sites to lower lying regions. Overall water capacity is low, placing additional emphasis on the need for irrigation.
