For Mondavi’s Fume Blanc ‘To Kalon Reserve’, the grapes are hand harvested in the cool of the morning and gently pressed as whole clusters, minimizing skin contact to retain freshness and vibrancy. Almost all of the juice is barrel-fermented in French oak, 42% new, for a slow, cool fermentation. Some of the juice ferments in two cement egg-shaped tanks. The wine is then aged on its lees (sûr lie) for nine months and hand-stirred (bâtonnage) twice weekly, for a creamy texture and to enhance the volume and length. A small amount of Semillon is added giving the final blend a richer mouth feel and further complexity.
