Rosé wines are generally made from red grape varieties such as Zinfandel in the United Stated and Grenache in France. The initial stages of the process are the same for rosé wines as it is for red or white wines. When the grapes have reached ideal maturation, they are gently harvested and brought to the winery. Upon arrival at the winemaking facility, they are tossed in the receiving hopper that evenly feeds the grape clusters into the crusher/destemmer and separates the leaves and stems from the grapes. Simultaneously, a small amount of sulfur dioxide is sprinkled over the crush to prevent spoilage and oxidation.
