From the Importer: "The Akutain Crianza is comprised of mostly Tempranillo with Garnacha, is fermented in fiberglass vats with native yeasts, and then raised for 1 year and 9 months in used American oak barrels, with an additional year in the bottle before release - far exceeding the Rioja D.O.’s aging requirements for Crianza wines. A very good value in traditional Grower Rioja."
