2023 was an atypical year. The winter season was hot and rainy, spring hot and dry, and the summer was moderately hot and rainy, especially in June and September. It was a year that, contrary to what happened in previous years, was wet, with the vines reaching the ripening period in an excellent state of hydration. Consequently, the white grapes reached higher levels of acidity and increased in aromatic freshness.

Altitude by Duorum expresses the unique character of the Upper Douro, transporting you to the panoramic high-altitude vineyards, which provide fresh, fruity, and vibrant wines and, as part of the Douro International Natural Park, constitute a refuge for local biodiversity. The vineyards at Castelo Melhor are a unique territory which protects three rupicolous bird species: the Egyptian Vulture, the Griffon Vulture, and the Black Stork (illustrated on the label).

A blend of Gouveio and Arinto e Rabigato which is aged on its lees for five months. Golden yellow color. Intense aroma of ripe lemon, pineapple, and light tropical notes. Fresh and elegant in the mouth, wrapped in tropical fruit, with a long finish.
