34 days without the Andes: what the Cristo Redentor closure cost Argentine wine

Between July 14 and August 18, 2026, the Cristo Redentor pass stayed closed for 34 straight days, longer than any winter on record, and shut again for a week at the end of August. The press counted the stranded trucks: more than 3,000 in Mendoza. Nobody counted the wine. With customs declarations line by line, Vinalitica did: week by week, market by market, exporter by exporter.

A country that exports by truck

Argentine wine does not leave through the port of Buenos Aires: it leaves over the Andes. From January to September 2026, 96.7% of export value travelled by truck and barely 3% by ship. Overseas markets (every destination except Brazil, Paraguay, Uruguay, Bolivia and Chile) account for 78% of sales, and 97.5% of that wine leaves the country by truck: to reach a port, that means crossing into Chile through the Cristo Redentor and loading at Valparaíso or San Antonio, the route logistics operators themselves describe as the fastest and cheapest. The United States, the United Kingdom and Canada, the three largest overseas customers, depend on the pass for 98%, 99% and 100% of their volume.

Brazil is the exception that serves as a control: it is also served by truck, but through Paso de los Libres and Uruguaiana, far from the snow. Whatever happens to Brazil in July and August is not the Andes.

Six weeks of a hole, not a blackout

The weekly curve says it all. Up to the week of July 6, 2026 was running level with or above 2025 in overseas markets. From the July 14 closure and for six weeks, truck shipments to overseas markets fell between −35% and −72% against the same week of 2025, bottoming out in the weeks of July 27 and August 3. The flow did not stop entirely: it dropped to a third. Part of the heavy traffic was diverted to the Neuquén passes, Pino Hachado and Cardenal Samoré, where some 600 trucks were queuing at the end of July (the detour adds about 2,000 kilometres and close to US$4,500 per truck, according to Mendoza hauliers), and part of the declarations were filed with customs while trucks waited in Mendoza.

Over two months, July and August, 7,403 truck shipments left for overseas markets against 10,558 a year earlier: 16.9 million litres against 27.7, and 208 active exporters against 244. It is a winter without precedent in the series. From 2022 to 2025, July-August always billed between 96% and 157% of May-June; in 2026, 71%.

Then came the rebound. From the week of August 24 to the end of September, every week beat 2025, peaking at +62% in the week of September 14. September closed with 7,835 shipments (+33%), 19.2 million litres (+30%) and +26.8% in overseas value: the best month of the year, built largely on wine that could not leave earlier.

Who paid: the markets

Not every destination suffered equally, and not all recovered. Canada (−40.5% in July-August), the United States (−36.6%) and the United Kingdom (−33.0%) absorbed most of the hole in value; France (−68%) and Germany (−57%) felt it harder in proportion. In September the United Kingdom (+33.8%), Canada (+31.3%) and Germany (+38.3%) bounced back strongly, and Mexico (+135%), Peru (+67%) and Colombia (+73%) ended the quarter above their first-half pace.

To measure what went missing, we compare the actual quarter with the one each market would have delivered at its first-half pace. Overseas, that calculation comes to US$19.4 million short: Canada −5.6M, the United Kingdom −5.3M, France −3.2M, the United States −2.3M (already falling before the closure) and Germany −1.7M. Western Europe accounts for US$12.8M of the hole; North America for 4.5M. Brazil also finished 9.7M below its pace, but with −12.5% in July-August and −10.8% in September: no snow there, just demand.

Exporter by exporter

At company level, the closure shows in shipping days. Grupo Peñaflor, the country's largest exporter, billed US$8.6 million less overseas in July-August than a year earlier and recovered 2.7 in September; its quarter ended at −18.8%. Trivento lost 3.3 and recovered 1.9; La Agrícola (Zuccardi) lost 2.7 and recovered 1.2. Cheval des Andes, whose big shipment of the year usually falls in winter, left 1.7M unshipped.

The hardest hit were those with the fewest shipping days: Finca La Celia went from 28 days with departures in July-August 2025 to 7; Salentein from 30 to 14; Norton from 31 to 17; Doña Paula from 25 to 16; Chandon from 23 to 15. Their quarters ended between −31% and −41%. Of the 26 exporters above US$1 million overseas in the third quarter of 2025, only 9 closed the 2026 quarter higher, and 18 stayed below their first-half pace. Seen by winery, Trivento (−1%), Finca Las Moras (+3.7%), Navarro Correas (+3.1%) and Zuccardi (+1.4%) saved the quarter; El Esteco (−44%), Chandon (−42%), Norton (−40%), Mascota (−39%), Doña Paula (−34%) and Salentein (−33%) did not.

Provinces: Mendoza and San Juan bounce back, Salta does not, Patagonia barely moves

Mendoza, home to most overseas wine, fell −32.6% in July-August and rebounded +23% in September. San Juan fell −40% and then doubled (+100%). Salta is the odd one out: −60% in July-August and still −18% in September, the only major origin that did not bounce back: its overseas wine also goes through the Mendoza customs office, more than a thousand kilometres from Cafayate. Wineries in Neuquén (−1%) and Río Negro (−9%) barely moved, but not because they have another way out: their overseas truck shipments are registered at the Mendoza customs office, like everyone else’s, and the crossing is the same. They are small volumes (US$1 million over two months) that travel in batches, and a larger share than in Mendoza leaves through the port of Buenos Aires: 14% of their overseas sales, against 2% for Mendoza.

The ship was not the relief valve

The obvious alternative, the port of Buenos Aires, did not act as one. Shipments by sea totalled US$2.0M in July and 2.2M in August, the same as in 2025 (2.2 and 2.4). Only in September did they rise, to 1.7M against 0.9, with 15 exporters instead of 10. Two companies did change route in the middle of the crisis: Bodegas Esmeralda (Catena) shipped by sea to the United States from August 14 (US$0.7M), and before that to China, Switzerland and Spain; Puerto Ancona did the same to the United States and Mexico. They are exceptions: a thousand kilometres of trucking to the port, different freight and different transit times cannot be improvised in three weeks. Trivento's CEO summed it up in September: “it is much cheaper to export from Chile”; his company sent only 15 containers through Buenos Aires “because it is much more expensive”, and he blamed the closure for an 80% drop in its bulk shipments.

Lost or deferred?

The overseas quarter closed at US$129.2M against the 148.6M the first-half pace would have delivered. Part of those 19 million was recovered in September and part will show in the fourth quarter: if October and November run above 2025 (the last quarter of 2025 totalled US$164.5M), it was deferral; if not, it was a sale lost on somebody else's shelf. Bottled wine to overseas markets fell −46% in July and −16.5% in August, then rebounded +28% in September; bulk, −72% in litres in August and +23.5% in September. By price tier, super premium (15 to 30 dollars a litre) rebounded most in September (+74%), followed by the economy tier (+59%); ultra premium (above 30) kept falling (−8%).

Argentine wine has no logistics plan B: when the Andes close, two thirds of the overseas flow stops, and the ship does not take over.Vinalitica analysis

What the winter leaves behind

The Cristo Redentor closes every winter; what is new is the length: 34 straight days, against the previous record of 26 in 2023, plus a second closure from August 24 to 31. The industry has talked for years about logistics costs as a competitiveness problem; this winter put a number on it. The alternatives under discussion, the southern passes with limited customs capacity, the port of Buenos Aires and, in the long run, the Agua Negra tunnel, all come at a price. What has no price is a shipping calendar that does not depend on July snow.

Method note. Wine export declarations from Argentine customs processed by Vinalitica; FOB values in dollars. The date is that of the declaration filed with customs, not the physical crossing. The transport mode is the one declared on leaving the country: ‘truck’ means a land crossing (into Chile for overseas destinations), ‘water’ means loading at an Argentine port (Buenos Aires). The INV publishes nothing by mode or port; its August figures (−27.8% in litres, bulk −75%, bottled −10%) match ours (−25.6%, −72%, −10%). 'Overseas' = every destination except Brazil, Paraguay, Uruguay, Bolivia and Chile, which travel through other passes. 'First-half pace' = third quarter of 2025 multiplied by each market's or company's January-June 2026/2025 change. 'Days with shipments' = distinct days with at least one overseas shipment in July-August. Province according to Vinalitica's winery registry (US$18M of the period with no province assigned). The customs office of registration is read from each declaration’s identifier (038 = Mendoza, 001 = Buenos Aires, 073 = Ezeiza, 075 = Neuquén, inferred from the flows).
