La Rioja (Argentina) Wine Region Guide

Geography and terroir

Founded by Spanish conquistadors in the 16th century, La Rioja has cultivated vines for over 400 years. Yet fame has arrived slowly in the province, partly because of its historic focus on growing bulk wine and high-yielding table grape varieties; La Rioja, despite sharing a name with Spain’s foremost wine region, produces no icon wines. The mutual nomenclature, however, has been a source of controversy and argument over the years, culminating in a legal dispute between producers in Spain and Argentina. In 2011, a judge decided that “La Rioja Argentina” could continue to be used on wine labels. The Spanish, to put it mildly, were less than thrilled.

However, their concerns were arguably unjustified. Situated northwest of Cordoba and encircled by the Sierra de Velasco, this very dry Argentine vineyard has little in common with Spain’s Rioja region. Indeed, temperatures in December and January can rise sky-high in this expansive zone, protected by the rain shadow of the Andes. As a result, irrigation (both flood and drip) is essential in La Rioja – viticulture would be impossible without it.

Meanwhile, La Rioja has to contend with approximately 200 mm of rainfall annually, while summer temperatures routinely exceed 87°F. This unique terroir, with its high altitude, intense sunlight, and significant diurnal temperature variation, contributes to La Rioja wines’ distinct taste and quality.

Potential for High-Quality Wine Production

Nevertheless, there is a great potential for high-quality wine production in La Rioja, located in the spectacular foothills of the snow-capped Andes. To the north is Cafayate, and the impressive wines of Salta–Mendoza are located to the south. Local growers estimate that about 7700 hectares are planted in the zone, including 2,150 hectares of Torrontés, 740 of Malbec, and just over 600 hectares of Syrah. They grow in several diverse subregions (with 12 distinct GIs in La Rioja), although the vast majority are planted in two key areas: Chilecito and Famatina.

Named after Chilean settlers who relocated to La Rioja in search of gold, Chilecito is home to some 80 percent of the region’s total acreage. It is a remarkable place, flanked by the Sierra de Famantina and covered in super-robust cacti. At times, Chilecito feels more like the set of a Hollywood Western than a commercial vineyard. And yet, over 6,000 hectares of vines are planted here in a steep and winding valley home to many olive trees.

The soil is alluvial and relatively young: free-draining terroirs that require carefully timed irrigation to prevent berry inflation and excessive yields. In Argentina, it is one of the most important factors differentiating bulk growers from quality-conscious firms.

However, the intensity of flavor that characterizes local wines comes from above rather than below. Intense sunlight bathes the vineyards in the province from dusk to dawn, producing high sugar levels in the grapes. Without the natural advantages of altitude and diurnal temperature variation, La Rioja would yield extremely alcoholic and jammy wines. This type of drink was fashionable in the 1990s, but not today.

Altitude Promotes Freshness and Elegance

Fortunately, many vineyards rise from over 850 meters above sea level to 1850 meters in certain places. Thus, much of the intense heat will escape fairly rapidly as the sun sets, leading to a significant difference between day and night time temperature; this helps to slow the vine’s metabolism and maintain sufficient levels of acidity in the grapes. When combined with the cool Alpine winds that blow off the mountains, La Rioja can yield some surprisingly fresh and elegant dry whites. It is this balance of ripe fruit and acidity that makes the best of Argentina so appealing.

Chilecito is the region’s most important subzone in terms of volume. However, the higher vineyards of the Famatina Valley produce the finest red wines. Malbec, Syrah, and Bonarda are the key varieties here. The best examples can rival Mendoza reds in their bracing freshness and rich fruit concentration, offering a unique and delightful tasting experience.

Winemaking and regional classifications

La Rioja has long been associated with Torrontés Riojano, a versatile white grape often grown on pergolas in the Chilecito and Famatina Valleys. The region’s most planted variety produces a broad range of styles, from unctuous dross to oak-aged blends. The sizable La Riojana cooperative is the grape’s biggest champion, fermenting some 20 million liters annually! Its products include a late-harvest dessert wine and a tank-method sparkling wine called Tilimuqui. It launched in the UK market in 2024 as one of the first Fairtrade sparkling wines made available to European consumers.

Indeed, La Riojana is a very impressive and influential business. Its commitment to ecological and social responsibility is at the heart of the cooperative’s DNA – La Riojana was founded over 80 years ago by a group of farmers in northwest Argentina. Cultivating a diverse palette of grape varieties in the province now involves 500 grower families who share land and resources. A market leader in organic and biodynamic wine (1,000 hectares certified as organic), La Riojana has invested over $3.5M(US) in Fairtrade community projects.

Its extensive range, meanwhile, encompasses 12 different brands, including Ecologica, Fair & Square, La Posada, and Riojana. The La Riojana cooperative significantly promotes the region’s wines, particularly the versatile Torrontés Riojano, to a global audience.

Innovations in Winemaking Techniques

However, La Riojana practices relatively standardized winemaking. Like its neighbors and competitors across Argentina, it typically ferments white grapes in stainless steel at low temperatures, using oak maturation sparingly. Yet La Riojana’s chief winemaker, Rodolfo Griguo, is known as the “King of Torrontés” in recognition of his pioneering work with the grape. Having developed a new strain of yeast to accentuate the grape’s inherent fruitiness, Griguol has also tirelessly worked to identify superior clonal material and discard high-yielding vines.

Thus, premiumized versions of Torrontés scarcely resemble the stale and flabby dross of old. The best examples combine sweet floral aromas – rose petal, geranium, and white peach – with a subtle saltiness on the finish. The fruit is piercingly aromatic, with citrus, rose water, and apricot on the mid-palate. Moreover, if the fruit is of sufficient quality, the grape can benefit from fermentation and maturation in wood, exemplified by Susana Balbo’s Signature Barrel Fermented Torrontes. It also blends very well with Chardonnay and Sauvignon Blanc, as demonstrated by the La Riojanas.

Beyond Whites: Syrah and Other Varieties

But there is more to La Rioja than floral-scented white grapes. Syrah, grown in the Famatina Valley, is a real competitor to local Malbec: an exotic and spicy interpretation of this noble variety, renowned for its voluptuous fruit and aromas of leather and damson. Cabernet Sauvignon and Bonarda can also thrive in La Rioja, although badly made wines from warmer sites can be very one-dimensional – vaguely reminiscent of a super-ripe Californian Merlot. Yet this is where the comparisons between La Rioja and the Golden State end.

The latter is awash with blue chip brands and mega-expensive collectibles; La Rioja has no fine wine industry to speak of. What it can offer, however, is some very well-made and delicious white, red, and sparkling wines. Very few labels rise above the $30 mark – a gift to younger oenophiles and bargain hunters everywhere.

La Rioja gastronomy

Argentines are consummate professionals at grilling meat, although La Rioja is not renowned for its sirloin, T-bone, or even rib eye steak. However, chivito (young goat) is a delicious local specialty that is available at all good parillas – ask for chivito asado if you want it barbecued. Locro (a rich and filling stew with meat and corn), empanadas, and regional pasta dishes should all keep your hunger at bay. But remember: this is no Buenos Aires. In the northwest, food is generally unpretentious, straightforward fare.
