Bodegas Iranzo exclusively makes wines from grapes grown in its own vineyards, entirely cultivated in accordance with EEC Regulation 2029/91 on organic agriculture. This is certified by the Organic Agriculture Committee of the Valencian Community, the arm of the Valencian Regional Government responsible for such matters.

Organic agriculture certification was awarded for the first time with the 1994 vintage, making Bodegas Iranzo one of the four oldest-established vineyards in Spain to apply this European regulation.
