Callebaut White Callets W2Callebaut White Callets W2 is as Belgian as can be, since it's predominately made with milk from cows grazing on Belgian pastures and sugar from locally grown sugar beets. It has a delightful taste with pronounced milky, creamy, caramelly and vanilla notes that are in perfect balance. W2 can be paired with a wide range of ingredients and flavors: from sour to bitter, spices to herbs and from fruits to beers.
