In the past, for Chileans, the stars in the night sky were both waypoints for survival and the destination of sacred souls. Indigenous peoples observed the movements of the sun, moon, stars and the Milky Way to understand the passage of time and the seasons. Changes in celestial bodies were the standard that determined farming, livestock movements and community rites, and part of a worldview that explained the relationship between humans and nature. They projected images of animals and nature not only onto bright stars but also onto the outlines of dark nebulae crossing the Milky Way. The night sky functioned as a calendar that marked time and as a language for reading the order of the great outdoors.
Today in Chile, the stars have also developed into a global scientific asset. The Atacama Desert in the north sits at high elevation with an extremely dry atmosphere, and it has clear nights with almost no clouds for more than 300 days a year. Low population density means relatively little light pollution, which also favors astronomical observation. For this reason, northern Chile concentrates many of the world's leading large observatories and observation facilities. That is why Chile's night sky is called the "eye of the Earth" through which humanity looks into the universe. Recently, as travelers from around the world come to Chile to witness the mysteries of the cosmos firsthand, stargazing has rapidly emerged as a core tourism industry.
The clear, dry environment where stars appear vividly is also a blessed natural setting for winemakers. It aligns with the natural conditions in which grapes grow healthily. A pristine climate where the Andes block clouds and westerlies cleanse the air provides abundant sunlight to the vines. Cool temperatures slowly ripen grapes to full maturity without fruit drop, helping rich sugar and high acidity achieve perfect balance.
Accordingly, Chile's stars and night sky have become themes for wine producers to express their brand identity. Sideral from Viña San Pedro, a winery with a long history, means "constellation" in Latin. Just as stars with different lights come together to form a constellation, the philosophy is that multiple grape varieties harmonize to complete a single bottle of wine.
Viña San Pedro was founded in 1865 by the Correa Albano brothers. It is now part of the VSPT Wine Group, which, along with Concha y Toro, represents Chile. It exports wine to more than 80 countries worldwide.
Most of San Pedro's top premium wines are produced in the Cachapoal Andes region at the foothills of the Andes. The area consists of coarse soils made up of colluvial deposits that have flowed down from the Andes over long ages, alluvial deposits carried by rivers, and volcanic rock mixed in varying proportions.
The winemaking process is carried out with equal delicacy. Grapes are harvested by hand and placed in 10-kilogram boxes. Using larger, heavier containers can crush the grapes at the bottom, so small boxes are used to reduce damage to the berries. Grapes are sorted three times: once at harvest in the vineyard, once on the sorting table at the winery, and once more after destemming.
Harvested grapes are protected with dry ice throughout the winemaking process to suppress oxidation. A gravity-flow method is also used to fill the fermenters instead of forcefully pumping the grapes. The aim is to minimize unnecessary mechanical impact and preserve the grapes' inherent aromas and flavors.
Before fermentation, the grapes undergo a cold soak at 8 degrees for 3 to 5 days. Selected yeast is then added, and alcoholic fermentation proceeds at 24 to 26 degrees for 10 to 12 days. Fifty-five percent of the wine ages for 16 months in French oak barrels, while the remaining 45% matures in amphorae of various sizes.
Sideral's varietal composition varies depending on the vintage's climate and grape condition. The 2022 vintage consists of 71% Cabernet Sauvignon, 21% Syrah, 5% Petit Verdot, 2% Carménère and 1% Cabernet Franc.
In the glass, it shows a deep ruby color. On the nose, ripe red and black fruits such as cherry and blackcurrant are vivid, followed by a light cedar note. On the palate, juicy fruit character and bright acidity come together, and distinct yet smoothly polished tannins give the wine its structure. Wine critic James Suckling gave Sideral 93 points for the 2022 vintage and 95 points for the 2018 vintage. At the 2026 Korea Wine & Spirits Awards, it won the grand prize in the New World red wine category. The domestic importer is Keumyang International.
