Style:

A fresh and vibrant Douro red, focused on elegance, drinkability, and purity of fruit. Light to medium-bodied, with a lively and expressive profile.

Vineyard:

Located in the Douro Valley, sourced from higher-altitude vineyards planted on schist soils. Cooler conditions help preserve acidity and freshness, resulting in a lighter and more delicate style.

Winery:

Hand-harvested grapes, partially whole-cluster fermented with native yeasts and gentle extraction. Aged mainly in stainless steel with minimal oak influence to preserve freshness and varietal expression.

Production:

~ 1,400 bottles

Nose/Palate:

Red berries, cherry, floral notes, and light spice on the nose, followed by a light to medium-bodied palate with bright acidity, soft tannins, fresh red fruit, subtle spice, and a clean, elegant, highly drinkable finish.

Cima Corgo is the heart of the Douro, centred around Pinhão and home to many of the region’s historic quintas. Its steep vineyards are dominated by poor, rocky schist soils, with altitude and exposure creating significant differences between individual sites. The warmer, drier climate compared with Baixo Corgo encourages deep ripening and concentration, while higher-altitude vineyards can retain impressive freshness and aromatic precision.

The classic red varieties are Touriga Nacional, Touriga Franca, Tinta Roriz, Tinta Barroca and Tinto Cão, often grown together in old mixed vineyards. Touriga Nacional contributes colour, structure, floral intensity and dark fruit; Touriga Franca brings perfume, ripe berry fruit and texture; Tinta Roriz adds spice and structure, while Tinto Cão contributes acidity and freshness.

Cima Corgo reds typically show black cherry, blackberry, plum and dark floral aromas, accompanied by violet, Mediterranean herbs, spice and a distinctive savoury or mineral character from the schist. On the palate they are generally full-bodied and structured, with ripe fruit, firm but polished tannins and vibrant acidity. The best examples combine power with a sense of verticality rather than becoming simply heavy or alcoholic.

Altitude is particularly important. Vineyards around 350–550 metres and higher can experience cooler temperatures and greater day-night variation, helping preserve acidity and produce reds with greater elegance and balance. Some high-altitude Cima Corgo vineyards therefore give a noticeably fresher and more refined interpretation of the region than the intensely ripe wines from lower, hotter sites.

The same terroir is fundamental to Vintage Port, for which Cima Corgo is historically the Douro’s central heartland. In dry DOC reds, however, producers increasingly use individual vineyards, altitude and indigenous varieties to express the region in a more precise and site-specific way.

Cima Corgo red wines combine the Douro’s natural power with remarkable structure and freshness — dark-fruited, mineral and savoury, with schist soils, indigenous varieties and altitude creating wines capable of both immediate richness and long ageing.

The story of Letra F begins with the historic system created to determine which Douro vineyards were best suited to producing Vinho do Porto. In 1935, the Portuguese authorities introduced the first formal criteria for selecting vineyards eligible for the benefício — the annual right to turn a certain quantity of grapes into Port. The original assessment focused particularly on factors such as altitude and soil, recognising their influence on the quality and ripening of the grapes. A vineyard register was then developed from 1937 onwards, and in 1947 the system was significantly expanded into a detailed points-based classification.

The vineyards were classified on a scale from Letra A to Letra F. The highest-rated A vineyards were considered the most suitable for Port, while progressively lower classifications received a smaller benefício. Letra F represented the bottom of the recognised scale, while vineyards below F had no entitlement to produce Port under the benefício system. The assessment considered a wide range of factors including altitude, slope, exposure, soil, location, grape varieties, vine age, planting density and productivity.

For Port, this hierarchy made sense: the system was designed to favour vineyards capable of producing ripe, concentrated and powerful fruit. Lower-rated parcels were therefore often regarded as less valuable because they were less naturally suited to the style of Port that the system sought to prioritise. Over time, some of these vineyards became economically marginal and were abandoned or neglected.

But this is where the story of Letra F becomes particularly interesting for dry Douro wines.

Many of these lower-rated vineyards were located in places that can be highly attractive for unfortified wine: higher elevations, cooler exposures and sites capable of producing grapes with more moderate ripeness and greater natural freshness. Instead of looking for maximum concentration for Port, producers making dry wines can use these characteristics to create wines with lower alcohol, brighter acidity, finer tannins and greater aromatic precision.

The survival of old mixed vineyards makes these parcels even more valuable. Rather than being replanted with a small number of commercially dominant varieties, some Letra F sites have preserved traditional field blends containing numerous indigenous grapes. In Cima Corgo, for example, Letra F vineyards can include extremely old vines growing at high altitude, with the combination of age, altitude and poor soils producing naturally low yields and concentrated but fresh fruit. Maçanita’s Letra F project in Carlão is an especially clear example, with 100–120-year-old vines at around 730 metres.

The resulting dry wines can therefore express a different side of the Douro. Instead of the massive, intensely ripe profile traditionally associated with the region, they can show red and dark berries, violet, herbs, spice and stony minerality, supported by vibrant acidity and fine tannins. The wines may be lighter in body, but they can have remarkable complexity because of old vines and the diversity of varieties within the vineyard.

This also helps explain why the modern revival of dry Douro wines has made Letra F increasingly interesting. The classification itself does not mean that an F-rated vineyard is objectively a poor vineyard for dry wine. It means that the parcel was considered less suitable for the specific requirements of the Port benefício system. Indeed, the same characteristics that reduced its value for Port can become advantages when the objective is freshness, elegance and terroir transparency. The IVDP still describes the A–F method specifically as a qualitative system used to select vineyards for Port production.

Letra F therefore tells an important story about the changing perception of Douro terroir. What was once considered the least valuable end of a Port classification can today represent some of the region’s most fascinating sources of dry wine — particularly when old vines, high altitude, traditional field blends and poor soils combine to produce wines of freshness, minerality and individuality.

The 2023 vintage in Cima Corgo followed the extreme heat and drought of 2022 with a considerably more moderate growing season. Winter and late-spring rainfall replenished water reserves in the soils, while moderate summer temperatures allowed the vines to continue ripening gradually without the severe heat stress seen in previous years. These conditions helped preserve natural acidity, freshness and phenolic maturity.

The harvest began relatively early, but the later stages were interrupted by several periods of September rain. This made careful selection and precise harvesting particularly important. The best parcels of Touriga Nacional and Touriga Franca were able to reach strong phenolic maturity, producing wines with excellent colour, freshness and balance.

The resulting reds show black cherry, blackberry, plum and violet, with Mediterranean herbs, spice and the savoury, stony character associated with Cima Corgo’s schist soils. On the palate, they combine ripe fruit with vibrant acidity, refined tannins and good mineral persistence, giving the wines both concentration and energy.

Compared with the very hot and concentrated 2022 vintage, 2023 is more balanced and lifted, with greater emphasis on freshness and aromatic precision. At the same time, it offers more ripeness and fruit depth than the cooler and more restrained 2021 vintage.

2023 Cima Corgo reds combine ripe Douro fruit with freshness and precision — a balanced vintage marked by deep colour, vibrant acidity, refined tannins and the mineral character of the region’s schist vineyards.
