Bin No. 27 is produced primarily from grapes from Fonseca’s own quintas in the Cima Corgo—exceptional fruit that results in a wine of high quality and consistency from year to year. In the winery, the newly developed, robotic “Port Toes” technology for treading the grapes allows the winery to maximize the quality of the fruit by imitating the traditional action of human feet and avoiding damage to the bitter grape seeds. Fermentation is halted by the addition of grape spirits before all the residual sugar has been fermented, creating a sweet, fortified wine. A ruby-style Porto blended from reserve wines selected for their intense depth of color and fruit character, Bin No. 27 is aged for four years in neutral wood vats before bottling.
