Producer Profile

COZs

COZs is the partnership of Portuguese natives Tiago Teles and António Marques da Cruz, founded in 2015 with a shared goal of reviving historic vineyards and native grapes in the Serra de Montejunto, just 15 km from the Atlantic Ocean in the Lisbon wine region.

Their story began with the purchase of a 60 year old Baga vineyard, followed by the limestone rich Vinha da Pena. In a region long shaped by conventional farming, COZs chose a different path, prioritizing organic agriculture and rethinking pruning and soil health. Today they work with six historic, high altitude sites planted mainly to Vital, with vines between 30 and 50 years old rooted in clay limestone soils.

Where The Wines Come From

Serra de Montejunto

The Serra de Montejunto is a rugged, high altitude wine area within Portugal’s Lisbon wine region, rising sharply above the surrounding plains about 15 kilometers from the Atlantic Ocean. This proximity to the coast gives Montejunto a distinctly Atlantic character, marked by cooling winds, high diurnal shifts, and long, slow ripening seasons.

Vineyards here are often planted on steep slopes and plateaus, with elevations reaching up to 350 meters. The dominant limestone and clay limestone soils contribute to naturally high acidity, firm structure, and a pronounced mineral edge in the wines. These conditions favor freshness and precision over power, making Montejunto especially well suited to native Portuguese varieties.

Historically, many vineyards in Serra de Montejunto were farmed conventionally or overlooked altogether. In recent years, a new generation of growers has returned to old sites, prioritizing organic farming and thoughtful vineyard work to unlock the region’s potential. Old vines of Vital, Arinto, Baga, Castelão, and other indigenous grapes are now being revalued for their ability to express place with clarity.

Wines from Serra de Montejunto tend to be vibrant, textured, and quietly complex. Whites show saline lift, tension, and subtle grip, while reds are fresh, savory, and structured without heaviness.
