White Zinfandel is a type of Rosé wine that falls between the categories of off-dry and sweet. It is made from Zinfandel grapes, which are typically used to produce a full-bodied and spicy red wine, also called Zinfandels. White Zinfandels were purportedly created by Sutter Home Family Vineyards winemaker Bob Trinchero in 1975 through a chance occurrence during the fermentation process. In 2018, Sutter Home held a significant market share in the White Zinfandel industry, accounting for 29.1% of the total dollar sales and 73.1% of the 187 mL (6.3 U.S. fl oz) segment of the market. Other wineries and beverage manufacturers also produce and sell this variety of wine.
