Ever since the first Cabernet Sauvignon vines were transported to Chile from Bordeaux during the 19th century, this sun-loving grape has been the driving force behind the country\u2019s wine industry.\r\n\r\nToday, roughly one of every three bottles of wine produced in Chile is varietal Cabernet Sauvignon. And while much of it is pedestrian and priced to sell, the country ranks among the global kings of Cabernet at the value-rich middle tier as well as the ultrapremium level. Ask winemakers what they believe are the world\u2019s best regions for growing potentially great Cab, and you\u2019re likely to hear three names: Bordeaux, Napa Valley and Chile\u2019s Maipo Valley.\r\n\r\nMaipo, you say? Let us tell you more.\r\n\r\n\r\n\r\nAbout halfway between the Andes Mountains and the Pacific Ocean, surrounding the capital city of Santiago, the Maipo Valley is Chile\u2019s original commercial wine region. It\u2019s blessed with warm days, cool nights, a prevailing dry climate, high elevations and alluvial soils that have been fed for millennia by the Maipo River.\r\n\r\nOther regions in Chile, like the Aconcagua Valley to the north of Santiago and the Cachapoal, Colchagua and Curic\u00f3 valleys to the south, also boast quality Cabs. But no place in this sliver of a country produces Cabernet like Maipo, just like no place in California does Cabernet Sauvignon like Napa, and no place in Europe makes it like Bordeaux\u2019s Left Bank.\r\nCabernet Today\r\n\r\n\r\nThe signature Chilean Cabernet Sauvignon is intense and generous, with firm yet pliable tannins, herbal overtones and loads of dark-fruit aromas and flavors. These wines are plusher than those from cooler climate Bordeaux, but less opulent and more spice-based than the fruit-forward Cabernet from Napa. The current vintage for high-end Chilean Cabernet is 2017, but wines from 2018, especially those priced from $15 to about $30, are now coming into the market.\r\n\r\nThe 2017 vintage was marked by intense summer heat and a very early harvest. But for some winemakers, it proved that established terroirs and vines of a certain age (30 years or older) impact the wines even more than weather.\r\n\r\n\u201cVintages like 2017, ones that you know are coming in warm, force you to pay attention,\u201d says Rafael Urrejola, winemaker for Undurraga. Its 2017 T.H. Cabernet, from an Alto Maipo vineyard planted three decades ago at about 2,200 feet, is tightly wound and a prime candidate for the cellar.\r\n\r\n\r\n\r\n\u201cIf you understand the ripening process and pick at the right time, the results should still be good,\u201d he says. \u201cBut if you are late in this type of year, you will end up with overripe, cooked and flat wines. The harvest window gets really narrow. For T.H. 2017, we picked by the second week of March, very early compared to other years.\u201d\r\n\r\nOnly 7.6 inches of rain fell from May 2016 through April 2017, according to the Servicio Agr\u00edcola y Ganadero, a government agency. The prior year saw 17.5 inches of El Ni\u00f1o-driven rain, much of it in April when Cabernet Sauvignon harvests generally reach their peak.\r\n\r\nAs for 2018, Chile\u2019s winemakers call it the best year in a decade or more, for all varieties and styles of wine. It was normal in terms of daytime and nighttime temperatures\u2014meaning excellent for Cabernet\u2014with an average amount of rainfall for the year, about 13.5 inches.\r\n\r\n\r\n\r\nWhat made it especially great for Cabernet, according to Sebastian Ruiz, winemaker with Vi\u00f1a Tarapac\u00e1 in the Isla de Maipo subzone, was that it allowed for a long hang time.\r\n\r\n\u201cThe Cabernet grapes were so healthy, with beautiful berries and bunches,\u201d he says. \u201cThe yield was 26% higher compared to 2017, but perfect temperatures during the maturation period determined a later than normal harvest. This always helps Cabernet Sauvignon wines to have good color, freshness of fruit, good natural acidity and elegant tannins.\u201d\r\n\r\nMarcelo Papa, technical director at Concha y Toro, called 2018 \u201cfantastic, probably the best year in the last 10. The wines are refined, with great precision of fruit. They are juicy and display magnificent balance.\r\n\r\n\u201cSomething I recall noticing was that the vines looked very comfortable throughout the season, and experience has taught us that a happy vine produces a happy wine.\u201d\r\n\r\n\r\n\r\nWinemakers noted that 2019 was a good year for Cabernet, but one where drought conditions returned. A mere 6.4 inches of precipitation fell during the May to April measuring period.\r\n\r\nThe 2020 vintage was one of the driest years on record with only 3.5 inches of rain, nary a drop during the growing period.\r\n\r\nLorena Mora, who heads the Terrunyo program at Concha y Toro along with veteran winemaker Ignacio Recabarren, says that until the past year, drought conditions in Chile have been manageable due to modern irrigation. But how long that can continue remains to be seen.\r\n\r\n\u201cWe are getting to the point where we cannot replace the lack of rain,\u201d says Mora. \u201cIn 2020, many vineyards had problems irrigating. It is a problem that has been intensifying year after year. In Maipo, the situation has us worried. We irrigated much more this past season, and we will have to adapt to this new reality.\u201d\r\n\r\n\r\n\r\nWith droughts come lower yields, something that hurts wineries that produce inexpensive wines designed for mass consumption. On the other hand, small yields tend to result in more concentrated wines.\r\n\r\nFernando Espina, head winemaker at Vi\u00f1a Chocalan in the Maipo Valley, whose 2018 Gran Reserva Origen Cabernet Sauvignon offers great value, put Chile\u2019s reduced rainfall into terms we all can understand.\r\n\r\n\r\n\r\n\u201cToday, we can talk about lower rainfall like the coronavirus pandemic,\u201d he says. \u201cWe are dealing with a new normal. But extremely low yields are not necessarily synonymous with good quality. Rather, it can translate into drying tannins, overripe fruit, dehydration and high alcohol.\u201d\r\n\r\nFortunately, the best of Chile\u2019s Cabernet Sauvignons deliver plush tannins, perfectly ripe fruit, juicy acidity and alcohol levels of about 14%. Wines like these are plentiful and calling your name.\r\n\r\n\r\nA Dozen Stellar Chilean Cabernets\r\nPick up an old favorite, or try something new.\r\nSix Well-Known Names\r\nVi\u00f1a Don Melchor 2017 Cabernet Sauvignon (Puente Alto); $120, 95 points.
