White port is a polarizing style of port produced by every major house on the Douro river. The style, often derided by traditionalists, has become increasingly popular as a chilled aperitif and mixing agent in cocktails. , White port is almost universally produced to a medium (or higher) sweetness level. Higher residual sugar levels are responsible for the sweetness and alcohol levels tend to be slightly lower than red-port styles. The wine receives little or no maceration during fermentation.
Of the 50 or so varieties permitted in a white-port blend, only half are actually white grapes.
