Sourced in the traditional way, from the highest-quality individual growers in the Douro Valley, where the varying altitude and aspect of the vineyards creates the potential for a complex wine of great character. Fermentation is halted by the addition of grape spirits before all the residual sugar has been fermented, creating a sweet, fortified wine. Fine Tawny is a blend of young wines matured in neutral oak casks for an average of three to four years before bottling.
