Syrah vs Grenache
Shiraz, which Wine Australia calls Australia's most planted winegrape variety, meets Grenache noir, which Inter Rhone calls the most-planted of its Rhône grape varieties: partners in the GSM blend that differ in vine, climate and structure.
Syrah and Shiraz are the same grape, Syrah the French name and Shiraz the Australian one, according to Decanter's WSET Level 2 guide (2015); the OIV's 2017 Focus on the world's grapevine varieties lists Grenache noir as Garnacha Tinta and gives Cannonau among its Italian synonyms. The OIV puts Syrah at 190,000 hectares in 31 countries in 2015 and Grenache noir at 163,000 hectares, with France and Spain holding 87 percent of Grenache's area. In the Rhône, Inter Rhone calls Syrah one of the most emblematic red grapes of the northern Côtes du Rhône and Grenache noir the king of the southern Rhône varieties; in Australia, Wine Australia's Variety Snapshots (prepared August 2026) place the Barossa Valley and McLaren Vale among the top five regions by crush for both.
Inter Rhone writes that Syrah was long believed to be Persian, Syrian or born in Syracuse, and that recent analyses show it took root in Savoie and Ardèche. The OIV's 2017 Focus on the world's grapevine varieties describes it as a black grape from the Rhône valley that genetic research suggests is a crossing of Mondeuse Blanche (from Savoie) and Dureza (from the Ardèche), and Decanter (2024) dates the confirming DNA profiling to 1998. In Australia it is called Shiraz; Decanter (2024) records that James Busby took cuttings, then called Scyras, to Australia in 1832.
Inter Rhone gives Grenache noir's origin as Spain (Aragon), and the OIV's 2017 Focus calls it an ancient black grape variety from Spain, thought to have been introduced to France during the Middle Ages. Decanter's 2020 guide to Spanish Garnacha says the Crown of Aragón took the vine to Sardinia, where it still grows under the name Cannonau. Wine Australia describes Grenache as one of the original varieties planted in Australia.
Wine Australia calls Shiraz relatively adaptable, able to grow in moderate to cool regions as well as warm areas, and says it thrives in moderate to warm climate areas. Inter Rhone gives its Rhône terroir as cooler hillsides. Decanter's WSET Level 2 guide (2015) says Syrah wines are produced in moderate and hot climates, the grape's thick skins needing plenty of sun to ripen.
Wine Australia says Grenache buds early and ripens late, so it is best suited to warmer climate regions. Inter Rhone gives its terroir as dry, poor soils, and the OIV's 2017 Focus calls it extremely drought resistant and able to adapt easily to different soil types. Decanter's 2020 Garnacha guide adds that it benefits from hot, windy, arid conditions with well drained, low nutrient soils.
The OIV's 2017 Focus describes Syrah as highly vigorous but of low fertility, with small-to-medium berries in large clusters, late budburst, a short ripening-maturity period and a late harvest, and yields of 3 to 8 tonnes per hectare. Inter Rhone, writing for the Rhône, classes it as early-ripening and says its branches require trellising.
The OIV's 2017 Focus describes Grenache noir as highly vigorous and upright, with high fertility and large clusters producing a high-to-medium yield, and susceptible to coulure; it gives the variety's yield as 2 to 8 tonnes per hectare. Inter Rhone classes its ripening as intermediate and calls it ideal for gobelet training, and Decanter's 2020 guide says it can be trained low to the ground as a bush vine thanks to its strong, upright canopy growth. Wine Australia warns that over-cropped Grenache can make simple wines and that low yields give higher quality, better structured wines.
Inter Rhone describes Syrah as floral, peppery and structured, with red and black fruit (raspberry, redcurrant, blueberry, blackberry), floral notes (violet, mignonette) and spice (truffle, pepper, licorice, menthol); with age its violet aroma evolves toward musk, truffle, leather, pepper or licorice. Decanter's WSET Level 2 guide (2015) links peppery spice, herbaceousness and smoky notes to moderate climates, and riper, even jammy fruit with sweet spice (liquorice) and dark chocolate to hotter regions. The AWRI identifies rotundone as the cause of black or white pepper flavour in Shiraz grapes and finds it most prevalent in cooler regions and cooler seasons.
Inter Rhone says Grenache noir makes very fruity, round wines, and Decanter's Grenache page calls them powerful, warming, raspberryish reds. Wine Australia describes Barossa Valley Grenache as medium to full-bodied and richly textured with red fruit, earth and white pepper character, and McLaren Vale Grenache as medium to full-bodied with rich texture, ripe juicy fruit and spice.
Decanter's WSET Level 2 guide (2015) says Syrah wines tend to be deeply coloured, with medium-high tannin and medium acidity, and are normally full-bodied; Inter Rhone calls its wines tannic but not very acidic. Decanter (2024) contrasts the Northern Rhône style (fine-grained tannins, higher acidity, a lean fruit profile, moderate body and alcohol) with the Australian Shiraz style, richer, riper and fuller in both body and alcohol. Wine Australia says Shiraz makes medium to full-bodied wines whose structure varies with region, climate and winemaking.
Decanter's 2020 Garnacha guide describes a thin-skinned grape that does not bring a lot of tannin to the wine and makes up for it in alcohol, often above 14% abv. Inter Rhone credits Grenache noir with weight and volume on the palate and a high alcohol potential, and Wine Australia says Australian Grenache ranges from medium weight to full flavoured and rich.
Decanter's WSET Level 2 guide (2015) says Syrah is regularly blended with Grenache to give it structure, boosting colour, tannin and acidity and adding dark fruit character to Grenache's red berry notes. Wine Australia says the Grenache, Shiraz and Mourvedre (GSM) blend has a long tradition in Australia, as does the Shiraz Cabernet blend, and that co-fermenting a small proportion of Viognier with Shiraz led to the Shiraz Viognier style. Decanter (2024) notes that while Grenache is usually the key grape in Southern Rhône reds, Syrah plays a key part, particularly in Châteauneuf-du-Pape.
Wine Australia calls the GSM blend the most popular Grenache-based wine in Australian exports and describes Barossa Valley Grenache as very important as the backbone to GSM blends; its Grenache Variety Snapshot (prepared August 2026) ranks the label claim 'Grenache, Shiraz, Mataro' first by value among those with Grenache in the name. The OIV's 2017 Focus says Grenache noir is often blended with other varieties to achieve a better balance. In Spain, Decanter's 2020 guide describes a supporting role in Tempranillo-led Rioja reds, contributing alcohol, body and aromatics, and Priorat blends with Cariñena and French varieties.
Inter Rhone lists Syrah's Rhône styles as still dry red and rosé wines, noting that it also makes fruity rosés. The AWRI reports that rosé-style wines have dramatically lower rotundone, the pepper compound, than equivalent wines fermented on skins.
Inter Rhone lists Grenache noir's styles as still dry red and rosé wines and sweet fortified wines (Vins Doux Naturels), and Decanter's Grenache page names fortified reds from Banyuls, Rivesaltes and Maury. Wine Australia says Grenache lends itself well to rosé and is still a key component in fortified wine production, and Decanter's 2020 guide says Rioja and Navarra favour it for rosado because of its low tannins, medium alcohol and fresh red fruit.
For Australian Shiraz, Wine Australia reports increased whole-bunch use with destemming still very common, less reliance on new oak (especially American), more use of French oak, and older barrels for subtlety, with some fresh, early-drinking styles seeing no oak at all. Decanter (2024) ties the Northern Rhône style to French oak and says Australian-style Shiraz is often matured in American oak.
For Australian Grenache, Wine Australia lists cold soaks before fermentation for aroma, whole-cluster and stem inclusion for structure and aromatics, extended post-fermentation maceration for tannin integration, and older (neutral) oak barrels for maturation. Decanter's 2020 guide says Garnacha can tend towards oxidation, and that most is better suited to large, used oak barrels (foudres) or neutral containers such as concrete eggs.
The OIV's 2017 Focus gives Syrah 190,000 hectares in 2015, grown in 31 countries, including 64,000 hectares in France (7.9 percent of the French vineyard), 40,000 hectares in Australia (26.8 percent of the Australian vineyard) and 20,000 hectares in Spain (2.1 percent). Inter Rhone's Syrah page puts it at 29.11 percent of the vineyards (no year given).
The same OIV study gives Grenache noir 163,000 hectares in 2015, with France and Spain together holding 87 percent of its world area: 81,000 hectares in France (10.0 percent of the French vineyard) and 62,000 hectares in Spain (6.4 percent). Inter Rhone's Grenache noir page puts it at 41.77 percent of the vineyards (no year given) and calls it the most-planted of its grape varieties.
Wine Australia calls Shiraz Australia's most planted winegrape variety. Its Shiraz Variety Snapshot (prepared August 2026) gives 39,893 hectares planted (ABS 2015), 29.5 percent of the national area, and 234,377 tonnes crushed in 2026, 18.5 percent of the total crush, with the Barossa Valley at 12 percent and McLaren Vale at 7 percent of that Shiraz crush. Wine Australia adds that the Langmeil Freedom vineyard in the Barossa is believed to have been planted in 1843 and is still producing.
Wine Australia's Grenache Variety Snapshot (prepared August 2026) gives 1,507 hectares planted (ABS 2015), 1.1 percent of the national area, and 13,550 tonnes crushed in 2026, 1.1 percent of the total crush, with the Barossa Valley at 30 percent and McLaren Vale at 18 percent of that Grenache crush. Wine Australia reports Grenache vines dating back to the late 1800s, especially in McLaren Vale and the Barossa Valley, a decline in plantings between 2000 and 2010, and an average Grenache grape value that in 2020 exceeded Shiraz's in McLaren Vale for the first time.
Wine Australia suggests charcuterie, grilled and roasted meats (lamb, beef and game), stews and casseroles, and firm, aged cheeses.
Wine Australia suggests grilled meats, game, lighter curries, light to moderately spiced dishes and charcuterie.
Reach for Syrah for the structure Decanter's WSET Level 2 guide (2015) describes, deep colour with medium-high tannin, and for the pepper the AWRI traces to rotundone, most prevalent in cooler regions and seasons. Reach for Grenache for the very fruity, round wines with high alcohol potential that Inter Rhone describes. Together they make the GSM blend: Decanter's guide says Syrah gives Grenache structure by boosting colour, tannin and acidity, and Wine Australia calls GSM the most popular Grenache-based wine in Australian exports.
