Chardonnay - Semillon wines are wine blends that are created using two elegant French grape varieties. They are commonly blended together in Australian wineries to create full - bodied and complex wines with smooth and waxy tropical flavours. Because these wine blends are generally produced in warm - climate regions, imparting a good acidic level to the wine becomes a difficult task. In this blend, Chardonnay grapes add tropical fruit flavours while the Semillon grapes impart a rich frame and texture to the Chardonnay characteristics in addition to adding nutty, strawy flavours and a lively zeal. Terrific wines have been created by blending together both these varieties but for the most part, winemakers produce low - budget Semillon - Chardonnay wine blends that are designed for immediate consumption. Food pairings that taste delicious with this blend are marinated white anchovies, sautéed mushrooms on polenta and roasted chicken with thyme.
