(19)Data on wine production and other market information, including stocks, are currently reported annually by Member States. Production and stocks notified are based on the declarations by producers and other operators referred to in Articles 31 and 32 of Commission Delegated Regulation (EU) 2018/273note and the specific rules laid down in Commission Implementing Regulation (EU) 2018/274note. While this yearly frequency is suitable to monitor production, it is not sufficient to monitor the evolution of the level of stocks, which strongly influences the situation of the market along the marketing year. A more detailed notification breakdown of the production and the stocks by colours and types of wine would facilitate the assessment of disparate market situations at Union level, facilitating the consideration of policy measures that are fit for particular needs.
