Along the coast of the Indian Ocean between Busselton and Perth, is a coastal limestone plain over which run a small number of rivers into the sea. Along the river banks are deposits of rich, red alluvial soil, approximately five metres deep, which lie over a limestone base. Both Capel Vale's Stirling and Wellington vineyards are situated on this terroir. These vineyards are trickle irrigated with pure, clean water with a guaranteed supply, supplemented by recycled treated waste water from the winery and bottling line.
The region enjoys a very mild climate with a strong Mediterranean influence. Summer days are generally warm but always end with a cool sea breeze that drops the temperature every afternoon. Rainfall occurs predominantly during the winter months.

This region is particularly recognised for chardonnays and merlots with excellent mid-palate weight and concentration and shows great promise for some other varietals including Petit Verdot, Viognier, Verdelho, Tempranillo and Sangiovese.
The Geographe region while cool, has an earlier vintage and can support varieties that would not ripen in Mount Barker and Pemberton.
