Organic wines are territorial expressions produced in compliance with European legislation that prescribes the use of only organically grown grapes, with restrictions on the use of sulphites and enological products during vinification. In order to comply with these requirements and thus be able to display the famous green logo on the label with the leaf formed by 12 stars that certifies organic production, producers may not use synthetic chemical products or genetically modified organisms in the vineyard and, in the cellar, may only use certified enological products, limiting the use of sulphites . Various certifying bodies have the task of ensuring that these conditions are respected, thus safeguarding the value of a rapidly growing production that is increasingly qualitative, sustainable, territorial and genuine.
