This wine is composed of 90% Hondarrabi Zuri and 10% Hondarabbi Beltza. The grapes are unique to the the Bask region and are not grown anywhere else in the world. Zundukarai is lovely, crisp and acidic and light in body . Historical in the Basque region fishermen found that many traditional wines could not survive the long time required for a voyage at sea. Txakoli became the wine of choice because its high acidity gave it a much longer shelf life .
