Although controls on grape harvesting and transport to wineries are carried out year-round, inspections intensify during the harvest, with daily operations. Speaking during an inspection in Amarante, in the Porto district, ASAE chief inspector Luís Lourenço explained: “The goal is to ensure the authenticity of Portuguese wine, of each region, so that consumers enjoy the best product possible.”

While the operation currently focuses on the Vinho Verde region, similar operations will extend to all wine-producing areas before the end of the harvest. Around 15 inspectors were involved in the last inspection, which covered the full commercial chain, from grape collection through to winery delivery. No irregularities were detected.

According to Mr Lourenço, inspections take place at every stage, including the retail sector, to safeguard the authenticity and quality for which Portuguese wine is known. Importantly, operators are not informed in advance, ensuring checks come as a surprise.

CVRVV president Dora Simões noted that the harvest in Vinho Verde has not yet reached its peak, but teams are already active in verifying grade deliveries. Inspectors are stationed both in vineyards and at wineries to confirm provenance.

“This ensures full traceability, confirming that the grapes delivered to the wineries genuinely come from the vineyard listed in the official records and declared in harvest and production reports,” she said.

These combined efforts aim to protect the reputation of Portuguese wine, reinforcing consumer trust and maintaining rigorous quality standards at one of the most crucial points in the winemaking process.
