Azal branco is a white Portuguese wine grape planted primarily in the Minho region. It noted for the high acidity of its wines, and is used for white Vinho Verde. Varietal Azal Branco wines can be somewhat reminiscent of Riesling.
Total Portuguese plantations are around 5,100 hectares (13,000 acres), which makes it the second-most planted grape variety of Minho, after Loureiro.
