New World Regional Varieties

New World Regional Varieties

The New World has its own set of regionally defining varieties — some transplanted from Europe and reinvented, some entirely new crossings created outside it. This section covers Zinfandel/Primitivo, Pinotage, Carmenère, Malbec, and Grenache in its Australian context.

Zinfandel (California) & Primitivo (Puglia)

DNA testing has confirmed that Zinfandel and Primitivo are genetically the same grape, grown under different names on opposite sides of the Atlantic.

• California — Zinfandel is treated as a heritage variety, with some vineyards containing vines over a century old (Old Vine Zinfandel, prized for concentration and complexity). The grape can produce an unusually wide stylistic range: from pale, off-dry blush rosé (White Zinfandel) to intensely ripe, high-alcohol, full-bodied reds bursting with blackberry, black pepper and dried-fruit character.
• Puglia (Italy) — grown as Primitivo, in Italy's warm southern "heel," producing a similarly ripe, jammy, warm-climate red style, often at excellent value.

Pinotage in South Africa

Pinotage is unique to South Africa: a deliberate crossing of Pinot Noir and Cinsault, bred in the Western Cape in 1925. It typically shows:

• Medium-to-high tannin
• Smoky, earthy character, sometimes with a rubbery or "bretty" note if not carefully made
• Plum and blackberry fruit

Pinotage is also the defining component of the Cape Blend, a distinctively South African style that combines Pinotage with Bordeaux varieties such as Cabernet Sauvignon and Merlot.

Carmenère in Chile

Carmenère has a remarkable history: originally one of Bordeaux's traditional blending grapes, it was thought to have died out after the phylloxera crisis of the late 19th century. In fact, it had survived in Chile, misidentified as Merlot for over a hundred years — the mix-up was only resolved by DNA analysis in the 1990s. Grown mainly in Chile's Central Valley (including Colchagua), Carmenère shows:

• Medium-to-high tannin
• Dark fruit — blackberry, black cherry
• A distinctive green bell pepper / herbal note when grapes are underripe, meaning the variety needs a long, warm growing season to fully ripen and lose this vegetal edge

Malbec in Mendoza, Argentina

Although originally a minor Bordeaux/southwest-France variety, Malbec found its true home in Mendoza, Argentina, where high-altitude vineyards (some planted above 1,000 metres) provide intense daytime sunshine combined with cool nights. This large diurnal temperature range preserves acidity and colour while still achieving full ripeness, producing:

• Full body and high tannin
• Dark fruit (blackberry, plum) with a floral violet note
• Frequently aged in oak, adding vanilla and mocha notes

Malbec's success in Mendoza transformed it into Argentina's signature grape and one of its most important wine exports.

Grenache in Australia: Barossa Valley & McLaren Vale

Australia is home to some of the world's oldest surviving Grenache vines — many over a century old, planted as low, unstaked bush vines that escaped the phylloxera epidemic thanks to Australia's geographic isolation. In the warm South Australian regions of Barossa Valley and McLaren Vale, old-vine Grenache produces:

• High alcohol, ripe red fruit, and soft tannin
• A key component of Australian GSM blends, pairing Grenache with Shiraz and Mourvèdre (locally often called Mataro) — a New World echo of the Southern Rhône blend covered earlier in this chapter

Zinfandel's Deeper Roots

Beyond its identity match with Primitivo, DNA research has traced Zinfandel back further still to a rare Croatian variety, Crljenak Kaštelanski, showing how the grape travelled from the Balkans to Italy and eventually to 19th-century California, where it became closely associated with old, dry-farmed vineyards in areas such as Sonoma and Lodi.

Chile's Varietal Labelling Rule

Chile allows a wine to be labelled with a single grape variety, such as Carmenère, provided it contains a minimum of 75% of that variety — a threshold worth knowing when comparing New World varietal labelling laws, since it is more permissive than many European single-varietal rules.

Argentina's Uco Valley

Within Mendoza, the Uco Valley is an increasingly important sub-region for premium Malbec, with some of the highest, coolest vineyard sites in the province; wines from here tend to show more pronounced acidity, floral lift and finer tannin than warmer, lower-altitude Mendoza sites.

Barossa Valley vs McLaren Vale

Although both regions excel with Grenache and Shiraz, they differ in climate: Barossa Valley is inland and warmer, tending to produce riper, more powerful wines, while McLaren Vale, closer to the coast, benefits from cooling sea breezes that can preserve a touch more freshness and elegance.

Quick Reference

Reading the Label

Unlike the European appellation-first labels seen throughout this chapter, New World labels typically foreground the grape variety name — "Mendoza Malbec" or "Barossa Valley Grenache" state the variety directly, with the region as supporting information. This variety-first labelling convention is one of the clearest structural differences between Old World and New World wine labels tested at WSET Level 2.
