The Fine Ruby Porto is made from selected grapes from the best vineyards of the Cima Corgo and Douro Superior. Taylor Fladgate is an area leader in winemaking technology, as one of only three Porto producers to pioneer the development of piston fermenter techniques, called Port Toes, which extract significantly greater flavor and aroma than conventional pump-over fermentation. Fermentation is halted by the addition of grape spirits before all the residual sugar has been fermented, creating a sweet, fortified wine.
