moved towards producing sparkling wines, they continued to produce both sparkling and still rosés often by means of blending a small amount of red wine to "color up" an already-made white wine. The depth of color was dependent on the amount red wine added, with the red wine having more influence on the resulting flavor of the wine if added in larger volumes. After World War II The history of rosé would take a dramatic turn following the conclusion of World War II when two Portuguese wine producer families both released sweet, slightly sparkling rosés to the European and American markets. These wines, Mateus and Lancers, would go on to set record sales in Europe and the US and dominate the Portuguese wine industry for most of the 20th century, but their popularity has declined in the recent years of the 21st century. While they still have a presence in the European and US markets, the trend towards traditional, drier rosés, as well as the development of American "blush" wines like White Zinfandel, have cut into their market shares. In the early 1970s, demand for white wine exceeded the availability of white wine grapes, so many California producers made "white" wine from red grapes, in a form of saignée production with minimal skin contact, the "whiter" the better. In 1975, Sutter Home's "White Zinfandel" wine experienced a stuck fermentation, a problem in which the yeast goes dormant, or in some cases dies off before all the sugar is turned to alcohol. Winemaker Bob Trinchero put it aside for two weeks, then upon tasting it he decided to sell this pinker, sweeter wine. In 1976, wine writer Jerry D. Mead visited Mill Creek Vineyards in Sonoma County, California. Charles Kreck had been one of the first to plant Cabernet Sauvignon vines in California, and offered Mead a wine made from Cabernet that was a pale pink and not yet named. Kreck would not call it "White Cabernet" as it was much darker in color than red grape "white" wines of the time, though not as dark as the rosés he had known. Mead jokingly suggested the name "Cabernet Blush"; later that evening, he phoned Kreck to say that he no longer thought the name to be a joke. In 1978 Kreck trademarked the word "Blush". The name caught on as a marketing name for the semi-sweet wines from producers such as
