George Husmann, The Cultivation of The Native Grape…
“ But nothing can be so absurd and unnatural than the practice of some, who will take away the leaves from the fruit, to hasten its ripening. The leaves are the lungs of the plants; the conductors and elevators of sap; and nothing can be more injurious than to take them away from the fruit at the very time when they are most needed. The consequence of such an unwise course will be the wilting and withering of the bunches, and, should they ripen at all, they will be deficient in flavor. Good fruit must ripen in the shade, only thus will it attain its full perfection. ”
