Australia (wine) in the context of "Müller-Thurgau"

The Barossa Valley wine region is one of Australia's oldest and prestigious wine regions. Located in South Australia, the Barossa Valley is about 56 km (35 miles) northeast of the city of Adelaide. Unlike most of Australia whose wine industry was heavily influenced by the British, the wine industry of the Barossa Valley was founded by German settlers fleeing persecution from the Prussian province of Silesia (in what is now Poland). The warm continental climate of the region promoted the production of very ripe grapes that was the linchpin of the early Australian fortified wine industry. As the modern Australian wine industry shifted towards red table wines (particularly those made by the prestigious Cabernet Sauvignon) in the mid-20th century, the Barossa Valley fell out of favor due to its reputation for being largely a Syrah from producers whose grapes were destined for blending. During this period the name "Barossa Valley" rarely appeared on wine labels. In the 1980s, the emergence of several boutique families specializing in old vine Shiraz wines began to capture international attention for the distinctive style of Barossa Shiraz, a full bodied red wine with rich chocolate and spice notes. This led to a renaissance in the Barossa Valley which catapulted the region to the forefront of the Australian wine industry.

Many of Australia's largest and most notable wineries are either headquartered or own extensive holdings in the Barossa Valley. These include such wineries as Penfolds, Peter Lehmann, Orlando Wines, Seppeltsfield, Wolf Blass and Yalumba. Many Shiraz vines in the Barossa Valley are several decades old, with some vineyards planted with old vines that are 100–150 years old including Turkey Flat in Tanunda that is home to the oldest commercially producing grape vines, originally planted in 1847. Other grape varieties grown in the Barossa Valley include Grenache, Mourvedre, Cabernet Sauvignon, Riesling, Chardonnay and Semillon.

Grenache (/ɡrəˈnæʃ/, pronounced [ɡʁənaʃ] ) or Garnacha (pronounced [ɡaɾˈnatʃa]) is one of the most widely planted red wine grape varieties in the world. It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape is believed to have originated. It is also grown in the Italian island of Sardinia, the south of France, Australia, and California's Monterey AVA, Paso Robles, Santa Barbara County and San Joaquin Valley.

It is generally spicy, berry-flavored and soft on the palate and produces wine with a relatively high alcohol content, but it needs careful control of yields for best results. Characteristic flavor profiles on Grenache include red fruit flavors (raspberry and strawberry) with a subtle, white pepper spice note. Grenache wines are highly prone to oxidation, with even young examples having the potential to show browning (or "bricking") coloration that can be noticed around the rim when evaluating the wine at an angle in the glass. As Grenache ages the wines tend to take on more leather and tar flavors. Wines made from Grenache tend to lack acid, tannin and color, and it is often blended with other varieties such as Syrah, Carignan, Tempranillo, and Cinsaut.

Riesling (/ˈriːslɪŋ, ˈriːzlɪŋ/ REE-sling, REEZ-ling, German: [ˈʁiːslɪŋ] ) is a white grape variety that originated in the Rhine region. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet, and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked. As of 2004, Riesling was estimated to be the world's 20th most grown variety at 48,700 hectares (120,000 acres) (with an increasing trend), but in terms of importance for quality wines, it is usually included in the "top three" white wine varieties together with Chardonnay and Sauvignon blanc. Riesling is a variety that is highly "terroir-expressive", meaning that the character of Riesling wines is greatly influenced by the wine's place of origin.

In cooler regions, such as the Mosel in Germany, Riesling wines often display apple and tree fruit notes with pronounced acidity that is sometimes balanced by residual sugar. As a late-ripening variety, Riesling can develop citrus and peach notes in warmer areas such as the Palatinate, Alsace, and parts of Austria. In Australia, Riesling is often noted for a characteristic lime note that tends to emerge in examples from the Clare Valley and Eden Valley in South Australia.

Chardonnay (UK: /ˈʃɑːrdəneɪ/, US: /ˌʃɑːrdənˈeɪ/; French: [ʃaʁdɔnɛ] ) is a green-skinned grape variety used in the production of white wine. The variety originated in the Burgundy wine region of eastern France, but is now grown wherever wine is produced, from England to New Zealand. For new and developing wine regions, growing Chardonnay is seen as a 'rite of passage' and an easy entry into the international wine market.

The Chardonnay grape itself is neutral, with many of the flavors commonly associated with the wine being derived from such influences as terroir and oak. It is vinified in many different styles, from the lean, crisply mineral wines of Chablis, France, to New World wines with oak and tropical fruit flavors. In cool climates (such as Chablis, the Willamette Valley of Oregon, and the Carneros AVA of California), Chardonnay wine tends to be medium to light body with noticeable acidity and flavors of green plum, apple, and pear. In warmer locations (such as the Adelaide Hills and Mornington Peninsula in Australia and Gisborne and Marlborough region of New Zealand), the flavors become more citrus, peach, and melon, while in very warm locations, more fig and tropical fruit notes such as banana and mango come out. Wines that have gone through malolactic fermentation tend to have softer acidity and fruit flavors with buttery mouthfeel and hazelnut notes.

Sauvignon blanc (French pronunciation: [soviɲɔ̃ blɑ̃] ) is a green-skinned grape variety that most likely originated in the Loire Valley wine region in France, though it has also been historically cultivated in Bordeaux. The grape most likely gets its name from the French words sauvage ("wild") and blanc ("white") due to its early origins as an indigenous grape in South West France. It is possibly a descendant of Savagnin. Sauvignon blanc is planted in many of the world's wine regions, producing a crisp, dry, and refreshing white varietal wine. The grape is also a component of the famous dessert wines from Sauternes and Barsac. Sauvignon blanc is widely cultivated in France, Chile, Romania, Canada, Australia, New Zealand, South Africa, Bulgaria, the states of Oregon, Washington, and California in the US. Some New World Sauvignon blancs, particularly from California, may also be called "Fumé Blanc", a marketing term coined by Robert Mondavi in reference to Pouilly-Fumé.

Depending on the climate, the flavor can range from aggressively grassy to sweetly tropical. In cooler climates, the grape has a tendency to produce wines with noticeable acidity and "green flavors" of grass, green bell peppers and nettles with some tropical fruit (such as passion fruit) and floral (such as elderflower) notes. In warmer climates, it can develop more tropical fruit notes but risks losing much aroma from over-ripeness, leaving only slight grapefruit and tree fruit (such as peach) notes.

Pinot noir (French: [pino nwar] ), also known as Pinot nero, is a red-wine grape variety of the species Vitis vinifera. The name also refers to wines created predominantly from Pinot noir grapes. The name is derived from the French words for pine and black. The word pine alludes to the grape variety having tightly clustered, pinecone-shaped bunches of fruit.

Pinot noir is grown around the world, mostly in cooler climates, and the variety is chiefly associated with the Burgundy region of France. Pinot noir is now used to make red wines around the world, as well as Champagne, and sparkling white wines such as the Italian Franciacorta, along with English sparkling wines. Regions that have gained a reputation for red Pinot noir wines include the Willamette Valley of Oregon; Carneros in Napa and Sonoma, Central Coast, Sonoma Coast, and Russian River AVAs of California; the Elgin and Walker Bay wine regions of South Africa; the Mornington Peninsula, Adelaide Hills, Great Southern, Tasmania, and Yarra Valley in Australia; and the Central Otago, Martinborough, and Marlborough wine regions of New Zealand. Pinot noir is the most planted varietal (38%) used in sparkling wine production in Champagne and other wine regions.
