2.8.91 Official Journal of the European Communities No L 214/39 COMMISSION REGULATION (EEC) No 2348/91 of 29 July 1991 establishing a databank for the results of analyses of wine products by nuclear magnetic resonance of deuterium THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Regulation (EEC) No 822/87 of 16 March 1987 on the common organization of the market in wine ('), as last amended by Regulation (EEC) No 1734/91 (%), and in particular Article 79 (3) thereof, Whereas the experience gained by the competent bodies in the Member States has demonstrated the need for more effective controls on the preparation of products which are offered on the wine market, in particular as regards compliance with national and Community provisions governing the adjustment of the potential and actual alco- holic strength of grape must and wines; Whereas the second subparagraph of "Article 16 (2) of Council Regulation (EEC) No 2048/89 of 19 June 1989 laying down general rules on controls in the wine sector (°), provides that each Member State must forward to the Joint Research Centre, hereinafter called the ‘JRC’, samples and analysis reports to be determined for the establishment of an analytical databank for wine products ; Whereas adjustment of the potential and actual alcoholic strength of grape must and wines by the addition of sucrose of concentrated grape must or of rectified concen- trated grape must is an oenological practice which is sometimes used fraudulently in that the approved limits are exceeded or the alcoholic strength of wine products which cannot legally by enriched is adjusted ; whereas the analysis of wine or wine products by nuclear magnetic resonance of the deuterium in the ethyl alcohol contained in these products is a method of analysis recognized by Commission Regulation (EEC) No 2676/90 (*); whereas the application of this method of analysis can improve . checks on the enrichment of wine products ; whereas, in order to facilitate interpretation of the results obtained by () OJ No L 84, 27. 3. 1987, p. 1. () OJ No L 163, 26. 6. 1991, p. 6. () OJ No L 202, 14. 7. 1989, p. 32. () OJ No L 272, 3. 10. 1990, p. 1. this method of analysis and to make it more trustworthy, an analytical databank should be created to enable comparison of the results obtained by the above method of analysis and those obtained using the same method during previous analyses of products with similar physi- co-chemical characteristics as a result of their originating in the same or in a neighbouring area and of other condi- tions of production ; Whereas detection of the enrichment of wines requires particular attention ; whereas, therefore at least initially, provisions should be made for the analytical databank to be restricted to date obtained from samples analysed by nuclear magnetic resonance of deuterium ; Whereas the analysis of wine products by nuclear magnetic resonance of deuterium is a relatively new method ; whereas to extend scientific exchanges between the official laboratories and promote cooperation in the interpretation of analytical results, the databank at the JRC should be accessible to the official laboratories using this method of analysis and to other official bodies requesting such access, subject to observance of the prin- ciples of the protection of private information ; Whereas the measures provided for in this Regulation are in accordance with the opinion of the Management Committee for Wine, HAS ADOPTED THIS REGULATION : Article 1 An analytical databank for wine products at the JRC is hereby established pursuant to Article 16 (2) of Regulation (EEC) No 2048/89. This databank shall be limited to data obtained from the analysis of wine products by nuclear magnetic resonance of the deuterium contained in the ethyl alcohol of the product in question in accordance with the method described in Chapter 8 of the Annex to Regulation (EEC) No 2676/90. The databank is to help harmonize interpre- tation of the results obtained by the official laboratories of the Member States by imposing the above method of analysis. '
