Albarino, also known as Alvarinho, is a white wine grape native to Galicia on the north Atlantic coast of Spain. It is best known for being the key grape variety in the Rias Baixas DO, where it produces crisp white wines with peach, citrus, and mineral characters. The variety is also used to make a lightly sparkling Vinho Verde wine in Portugal. Albarino is high in acidity and can be produced in a light or full style, with oak or lees aging adding to its texture and richness. Its marine characteristic and ability to cope with maritime macroclimates has led to its planting in various other parts of the world such as California, Oregon, Washington, and New Zealand. Despite its popularity, there are still challenges in identifying Albarino correctly as it has a tendency to mutate and adapt to its environment.
