The Peel wine subregion of Western Australia is located in the southwest corner of the state, bordered by the Perth Hills to the north and Geographe to the south. This region has a Mediterranean climate characterized by mild, wet winters and hot, dry summers, creating ideal conditions for growing a variety of grape types. Sea breezes from the Indian Ocean help moderate temperatures, ensuring optimal grape ripening conditions. The Peel region features a diverse landscape, from sandy beaches and dunes near the coast to rugged terrain near the Darling Ranges further inland.
Shiraz and Chardonnay are two prominent grape varieties in the Peel region. Shiraz is known for its ripe berry flavors, while Chardonnay offers a spectrum of styles ranging from refreshing and elegant to rich and buttery. Other notable varietals in the region include Cabernet Sauvignon, with style variations influenced by altitude, and Chenin Blanc, the first white grape planted in the area, known for wines that can age for five years or more.
The Mediterranean climate of the Peel region is shaped by its proximity to the ocean, with sea breezes cooling the western areas and temperatures decreasing as altitude rises towards the Darling Range. The region receives an average growing season rainfall of 177mm, with a mean temperature of 23.4°C. Lakes, dams, and the Indian Ocean contribute to a consistent supply of cooling sea breezes during the summer months. The Peel region's soil composition varies, with older granite and gravel soils in the eastern extension contrasting with limestone sands and fluvial sediments along the coast, containing significant groundwater reserves below the surface.
