João embodies a blend of pioneering spirit, commitment to preservation, diligent labor, and deep-rooted historical appreciation. Hailing from the north of Portugal, he and his wife Luísa relocated to Penalva do Castelo in Dão during the early 1990s. Their stewardship of Quinta da Boavista has been marked by both significant setbacks and notable triumphs.

The Tretas, a wine crafted under João's guidance, consists of 70% Jaen (also known as Mencia), 20% Rufete, and 10% Touriga Nacional. Fermented and aged in stainless steel for nine months, it emerges as a vibrant and lively offering. Bursting with the flavors of strawberries, raspberries, and morels, it offers a hint of dry tannins wrapped in a silky texture. Ample acidity provides a refreshing backbone to this medium-bodied red, concluding with a crisp, mineral-infused finish.
