Portoannual, night of 23 to 24 June1 night
Porto's midsummer street festival on the night of 23 June, celebrated for more than six centuries, fills the city with grilled sardines, bonfires, plastic hammers and free-flowing Vinho Verde and Douro wine until dawn.
Tip: The riverside Ribeira and the Fontainhas neighbourhood are the liveliest; base in Porto for the night, then escape to the quiet valley to recover the next day.
Pinhao and the Cima Corgoannual, mid September to early Octoberharvest season, roughly four weeks
Across the vindima, quintas open the harvest to guests for grape picking on the terraces, traditional foot-treading in granite lagares after dark and long harvest feasts. It is the most atmospheric time of the Douro year.
Tip: Choose an estate that still treads by foot for the full lagarada ritual; the popular September dates sell out by late summer.
Peso da Reguaannual, late August around the start of harvestseveral days
Regua's harvest-season wine festival fills the riverside town with tastings of local Port and Douro table wines, regional gastronomy, grape-stomping demonstrations and live music against the terraced slopes of the valley.
Tip: It coincides with the start of the harvest, so pair it with a quinta visit nearby to watch picking and fermentation begin.
Douro and Tras-os-Montesannual, around 11 Novemberaround Saint Martin's Day
Around Saint Martin's Day on 11 November, villages light bonfires, roast chestnuts and tap the first young wine of the harvest in the magusto feast.
Tip: Seek out village tascas serving agua-pe and jeropiga alongside roast chestnuts, the rustic part-fermented drinks of the new-wine season.
