Augustannual, August during harvest1 dayTicket needed
Each August during the harvest, Santo Wines opens its hilltop cooperative facility above Pyrgos for a public harvest-experience day. Visitors observe arriving grape loads at the receiving bay, walk through the production cellar, and taste the cooperative's current Assyrtiko and Vinsanto releases. The event combines wine education with the cooperative's panoramic caldera-view terrace and is the most accessible way to see Santorini harvest at scale.
Host: Santo Wines Cooperative (Union of Santorini Cooperatives)
Featured producers: santo-wines
Tip: Book the harvest-day experience directly through Santo Wines' visit-us booking system in advance; spots fill rapidly during peak harvest weekends.
