Aranda de Duero's main town festival overlaps with the harvest season and includes wine-themed events, peñas (private wine clubs) celebrations in the underground bodegas, and the 'Fiesta de las Penas' where wine clubs open their subterranean cellars to members and invited guests. The underground bodega network - 136 catalogued cellars with 4.2 km of galleries - is at its most socially active during the September festivities. Lechazo (roast suckling lamb) is the centrepiece gastronomy, paired with local Ribera reds.
Peñafiel's annual town festival held beneath the hilltop castle - itself home to the Museo Provincial del Vino. Wine is inseparable from the celebrations: the castle's museum hosts special evening tastings and Bodegas Protos, whose cellars extend beneath the castle walls, often opens for extended visits during the fair. The event coincides with the weeks before harvest, when the grapes hanging on the terraced vineyards below the castle are approaching full ripeness.
The Ribera del Duero DO takes part annually in the Vino + Tapas event on Valladolid's main promenade. Winery stands pour current releases - Roble, Crianza, and Reserva - alongside local tapas producers.
The Ruta del Vino Ribera del Duero coordinates open-cellar and tasting weekends across its certified member bodegas throughout the year, with concentrations in spring (April-May) and post-harvest (October-November).
The regional government of Castilla y Leon organises an annual Dia del Enoturismo (Wine Tourism Day) in November to promote off-season visits to the region's wine routes.
Roa de Duero, a historic hilltop wine town in the Burgos sub-zone, holds its annual town fair in late September coinciding with the start of Tinto Fino harvest.
The DO's flagship harvest festival, held annually in Aranda de Duero since 2018 (eighth edition in 2025). Features winery booths in the Plaza Mayor offering tastings, traditional grape-treading ceremony, live music, and lechazo gastronomy. Multiple bodegas participate; tasting wristbands give access to all producer stands. A cultural programme accompanies the wine content.
