The McLaren Vale wine region is located less than an hours drive south of Adelaide, along the coastline.
Shiraz is by far the most widely planted variety, and the most important variety for the region, accounting for about 50% of the total crush. Every winery in the region will likely be producing at least one or more Shiraz wines, and with the wide range of unique terroirs available, each influenced by the maritime climate in unique ways, each Shiraz will have its own regional nuances.
Shiraz produced in McLaren Vale will often exhibit chocolate and coffee notes, with a little less pepper than those from Barossa Valley, and are often blended with Grenache. Other red varieties grown include Cabernet Sauvignon (and Merlot blends) Sangiovese, Tempranillo, Petit Verdot, Tannat and Zinfandel. The main white variety would be Chardonnay, however Semillon and it's common blending partner Sauvignon Blanc are made, alongside lesser amounts of Riesling, Pronto Bianco, Vermentino and Fiano.
If you plan to visit McLaren Vale there are over 65 cellar doors so you'll be spoiled for choice, ranging from the small-boutique wineries to very large wineries. The drive from McLaren Vale up to the Barossa Valley is very scenic, passing over the rolling Adelaide Hills, and though the quaint German-settled town of Hahndorf.
