— About half of the 9,000 seasonal workers harvesting grapes in Brazil’s Serra Gaúcha wine region now come from Argentina, driven by the peso’s collapse and the end of minimum prices for yerba mate under President Milei
— Workers from Misiones province earn R$180 to R$200 ($32–$36) per day picking grapes — the equivalent of two and a half days’ wages in Argentina
— The trend accelerated after a 2023 slavery scandal forced formalization of the sector, with registered seasonal workers rising 300%, but also pushing Brazilian workers away from formal contracts
The Argentine workers in Brazil’s grape harvest have gone from a curiosity to a structural feature of the country’s wine industry in a single generation. About half of the 9,000 seasonal workers picking grapes across the Serra Gaúcha — Brazil’s most important wine-producing region in Rio Grande do Sul — now come from Argentina, according to the Consevitis institute that oversees the state’s wine sector. The migration has consolidated in 2026 as the intersection of two crises: Argentina’s economic collapse under President Javier Milei, and Brazil’s chronic shortage of rural labor that nearly destroyed the industry’s reputation three years ago. The Rio Times covers Latin American financial news and the cross-border labor dynamics reshaping both economies.
Why Argentine Workers in Brazil Earn More Picking Grapes
The economics are stark. A grape picker in the Serra Gaúcha earns R$180 to R$200 ($32–$36) per day. For workers from Misiones province, which borders Rio Grande do Sul, that daily wage equals roughly two and a half days of work at home. The math changed decisively when the Milei government eliminated minimum prices for yerba mate, one of the most important crops for Misiones’ small farmers. Before the reform, prices were set by the National Yerba Mate Institute (INYM); after it, they collapsed from 340 pesos per kilogram (ARS$340, or $0.34) to 180 pesos ($0.18), even as inflation drove up the cost of everything else. For small producers who depended on yerba mate as their primary income, crossing the border to pick grapes became survival arithmetic, not a lifestyle choice.
In January and February, between 400 and 500 workers were crossing the Uruguay River daily by ferry between Alba Posse in Misiones and Porto Mauá in Rio Grande do Sul, according to Argentine media reports. Many bring experience from Argentina’s own wine regions — Mendoza, Río Negro, and San Juan — and adapt quickly to the Brazilian system. Producers say the Argentines consider grape-picking lighter work than yerba mate harvesting, which takes place in exposed sun, while vineyard labor is done in the shade of the canopy. Between 2020 and 2024, Argentine residence visa issuance in Brazil rose approximately 30%, driven by the peso’s devaluation and facilitated by Mercosur’s residency agreements.
From Slavery Scandal to Formalization
The Argentine influx is filling a gap that nearly became a catastrophe. In February 2023, over 200 workers were rescued from conditions analogous to slavery during the grape harvest in Bento Gonçalves, one of the Serra Gaúcha’s main wine towns. Major wineries Aurora, Garibaldi, and Saltão signed conduct agreements and paid R$7 million ($1.2 million) in damages. In January 2024, another 18 Argentine workers were rescued from a property in São Marcos under similar conditions. The scandals triggered what the industry calls the “Pacto da Uva” — a formal agreement between the Labor Ministry, unions, and employers to eradicate middlemen and register every seasonal worker. The result was a 300% increase in formalized harvest workers, from 851 registered in 2023 to 3,417 in 2024.
But formalization created its own paradox. Many potential Brazilian workers receive government welfare benefits and fear losing them if they appear on formal payrolls, so they refuse seasonal contracts. This has accelerated the shift toward foreign workers who are eager for formal employment. Local unions now help Argentine workers obtain CPF tax numbers, register employment contracts in Brazil’s e-Social system, arrange occupational health exams, and process contract terminations at the end of each season. Producers provide dormitories, meals, and protective equipment on-site — a transformation from the pre-2023 model where middlemen controlled every aspect of workers’ lives. What was once a seasonal curiosity is becoming permanent: the phenomenon of Argentine workers in Brazil is no longer limited to the harvest, with families settling in Bento Gonçalves year-round and finding employment in supermarkets, factories, and the service sector across the region.
