Azal branco is a white Portuguese wine grape[1] planted primarily in the Minho region but with greater expansion to Amarante, Basto, Baião and Vale do Sousa sub-regions.
[2] It noted for the high acidity of its wines, and is used for white Vinho Verde.
[3] 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.
[4] The Azal variety provides an intense green color when maturated and an aroma of citric fruits (such as lemon or green apple)[5] and nuts.
