An old grape variety of exceptional quality, deservedly famed for the varietal wines it produces in the Vinho Verde region, specifically in the two sub-regions of Monção and Melgaço. Alvarinho has a highly characteristic floral and fruity profile with notes of lime tree, balm mint, honeysuckle, peach, grapefruit and apple, all well-married with the high acidity typical of crisp white wines from north-west Portugal. The grapes yield balanced wines with good structure and alcohol levels. Alvarinho’s qualities are being “exported” to more southern wine regions such as the Setubal Peninsula and Estremadura.
