Founded in 1820 by William and John Graham in Portugals Douro Valley, for nearly two centuries Grahams has cultivated its reputation as one of the greatest names in Port. The quality of Grahams Port relies on the finest grapes, primarily sourced from five iconic quintas in the Douro Valley. Located in the heart of the Upper Douro Valley, all of these quintas enjoy the hot and dry microclimate and unique schist soil only found in this region. Together these two factors provide the perfect conditions for both the growth and optimum ripening of the grapes.
