Winemaking in the Carinena region has a long history. Indeed, it is the oldest denomination in Aragon, and one of the oldest in Europe. In 1585, King Philip II visited Carinena, and in celebration the town's central water fountain ran with wine. Today, this is still commemorated by Carinena during the annual wine festival held in September when the fountain can be seen to run with wine instead of water. Situated in the province of Zaragoza, Carinena covers an area of 16,600 hectares consisting of 60 vineyards which produce 72.6 million litres of wine annually. Carinena is also a grape variety, however ironically Garnacha Tinta is the most widely-planted red grape variety in this DO, while Macabeo is the most popular white wine grape variety. Nevertheless, Chardonnay, Merlot, Syrah and Cabernet Sauvignon also do well here.
