Trás-os-Montes ('Behind the Mountains') is Portugal's most remote and least-known wine region — a high plateau beyond the Marão and Montesinho mountains in the far northeast, bordering Spain's Galicia and Castile. The extreme continental climate (the coldest winters and hottest summers in Portugal) and the schist and granite soils at 600–900m produce wines of distinctive character: ancient indigenous varieties including Rabigato, Viosinho, and Códega for whites, and Bastardo, Trincadeira, and Touriga Nacional for reds. The wines are rough-hewn, authentic, and deeply Portuguese.
