Marquis Philips Holly's Blend 2003
A large, climatically diverse country with incredibly diverse terrain, producing just about every wine style imaginable, Australia has a grand winemaking history and some of the oldest vines on the planet. Most regions are concentrated in the south of the country with those inland experiencing warm, dry conditions and those in coastal areas receiving tropical, maritime or Mediterranean weather patterns. Australia has for several decades been at the forefront of winemaking technology and has widely adopted the use of screwcaps, even for some premium and ultra-premium bottles. Thanks to the country’s relatively agreeable climate throughout and the openness of its people, experimentation is common and ongoing.
Shiraz is indeed Australia’s most celebrated and widely planted variety; Barossa Valley leads the way, producing exceptionally bold and supple versions. Cabernet Sauvignon, Australia's second most planted variety, can be blended with Shiraz but also shines on its own particularly in Coonawarra and Margaret River. Grenache and Mourvèdre are also popular, both on their own and alongside Shiraz in Rhône Blends. Chardonnay is common throughout the country and made in a wide range of styles. Sauvignon Blanc has recently surged in popularity to compete with New Zealand’s distinctive version and Semillon is often blended in Margaret River or shines on its own in the Hunter Valley. Riesling thrives in the cool-climate Clare and Eden Valleys. Sticky-sweet fortified wine Rutherglen is a beloved regional specialty of Victoria.
With hundreds of white grape varieties to choose from, winemakers have the freedom to create a virtually endless assortment of blended wines. In many European regions, strict laws are in place determining the set of varieties that may be used, but in the New World, experimentation is permitted and encouraged. Blending can be utilized to enhance balance or create complexity, lending different layers of flavors and aromas. For example, a variety that creates a soft and full-bodied wine would do well combined with one that is more fragrant and naturally high in acidity. Sometimes small amounts of a particular variety are added to boost color or aromatics. Blending can take place before or after fermentation, with the latter, more popular option giving more control to the winemaker over the final qualities of the wine.
