Commission Regulation (EC) No 625/2003 of 2 April 2003 amending Regulation (EC) No 1623/2000 laying down detailed rules for implementing Council Regulation (EC) No 1493/1999 on the common organisation of the market in wine with regard to market mechanisms
Commission Regulation (EC) No 625/2003
of 2 April 2003
amending Regulation (EC) No 1623/2000 laying down detailed rules for implementing Council Regulation (EC) No 1493/1999 on the common organisation of the market in wine with regard to market mechanisms
THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Community,
Having regard to Council Regulation (EC) No 1493/1999 of 17 May 1999 on the common organisation of the market in wine(1), as last amended by Regulation (EC) No 2585/2001(2), and in particular Articles 26, 33 and 36 thereof,
Whereas:
(1) Chapter I of Title I of Commission Regulation (EC) No 1623/2000(3), as last amended by Regulation (EC) No 1795/2002(4), lays down the detailed rules for applying the aid scheme for the use of grapes, grape must, concentrated grape must or rectified concentrated grape must. Experience has shown that the comestible products not eligible under the scheme should be specified in greater detail, the administrative burden placed on users and processors of juice should be lightened and adequate arrangements should be introduced to ensure that proper use of the juice is monitored. The percentage of quantities of comestible products which must be checked must be higher than under other schemes because the product is often used in a Member State other than the one where the aid is paid.
(2) Under the aid scheme for must used to increase the alcoholic strength of wine products, the reference to the method of determining alcoholic strength should be corrected. To facilitate the work of the Member States, they should be responsible for the administration of aid applications. To allow detailed and effective checks, checking arrangements should be specified.
(3) To ensure that problem cases are treated equally, the provisions relating to payment of the aid provided for under the various aid schemes covered by Regulation (EC) No 1623/2000 should be harmonised.
(4) To allow detailed and effective checks to be carried out in the case of aid for the private storage of wine, checking arrangements should be laid down and the tolerance margins for verifying the alcoholic strength of grape must, concentrated grape must and rectified concentrated grape must should be clarified. To facilitate the payment of advances under this measure, the related administrative procedure must be changed.
(5) As regards the arrangements for the distillation of by-products of wine-making, it is fair to modulate aid and prices according to the type of by-product concerned. The flat-rate aid and the flat-rate price should therefore be abolished. In addition, in order to respond to structural changes in the sector, the Member States concerned should be allowed to extend the exemption from the obligation to deliver by-products for distillation to certain categories of producers.
(6) If a Member State decides to vary the buying-in price paid to producers according to yield under the distillation arrangements referred to in Article 28 of Regulation (EC) No 1493/1999, it should be possible to extend the deadline by which the aid is to be paid to distillers.
(7) To ensure that financial transactions under crisis distillation as provided for in Article 30 of Regulation (EC) No 1493/1999 are properly implemented, it should be confirmed that the advance on the price to be paid to distillers by the intervention agency is to be treated the same as the aid provided for in the case of other distillations.
(8) For all distillation measures, the provision relating to the use of part of the wine checked as being representative of all wine delivered for distillation should be abolished. In addition, the advances paid for crisis distillation and treated as aid should be included in the system of penalties, and the same arrangements should be introduced for all the different distillations to ensure that producers are paid the minimum price for their wine where the distiller fails to do so.
(9) Experience has shown that the arrangements for disposing of alcohol obtained under the different distillation measures and held by the intervention agencies should be adjusted. The deadlines for removing alcohol should therefore be fixed on a case-by-case basis where large quantities are involved. To enhance marketing opportunities the present geographical limitations on sales of alcohol should be removed. The conditions for checking the destination of alcohol used in the fuel sector should also be specified.
(10) Since managing the intervention measures requires the Member States to provide the Commission with a great deal of information, the rules for doing so should be laid down.
(11) Regulation (EC) No 1623/2000 should therefore be amended.
(12) Some amendments aim to clarify existing provisions or to provide additional information and are favourable to market operators. They should therefore apply retroactively.
(13) Other amendments aim to improve the conditions governing isolated measures for disposing of alcohol. They should therefore apply from the publication of this Regulation.
(14) By far the majority of amendments provide for technical changes in market management measures. To avoid disrupting the current wine year, these amendments should apply from the next wine year.
(15) The measures provided for in this Regulation are in accordance with the opinion of the Management Committee for Wine,
HAS ADOPTED THIS REGULATION:

Method 13: Determination of 14C content in ethanol
1. METHOD TO DETERMINE TYPE OF ALCOHOL
Determination of the 14C content in ethanol permits a distinction to be made between alcohol from fossil fuels (synthesis alcohol) and alcohol from recent raw materials (fermentation alcohol).
2. DEFINITION
The 14C content of ethanol is understood to be the 14C content determined using the method described here.
The natural 14C content in the atmosphere (the reference value), which is absorbed by living vegetation by assimilation, is not a constant value. The reference value is therefore determined on ethanol from raw materials of the most recent vegetation period. This annual reference value is determined each year by collaborative analyses organised by the Community Bureau of References and the Joint Research Centre, Ispra
3. PRINCIPLE
The 14C content of samples containing alcohol with at least 85 % mass ethanol is determined directly by liquid scintillation count.
4. REAGENTS
4.1. Toluene scintillator
5,0 g 2,5-diphenyloxazole (PPO)
0,5 g p-bis-[4-methyl-5-phenyloxazolyl(2)]-benzene (dimethyl-POPOP) in 1 litre analytical grade toluene.
Commercial, ready-to-use toluene scintillators of this composition can also be used.
4.2. 14C standard
n-Hexadecane 14C with an activity of about 1 × 106 dpm/g (approximately 1,67 × 106 cBq/g) and a guaranteed accuracy of determined activity of ± 2 % rel.
4.3. 14C-free ethanol
Synthesis alcohol from raw materials of fossil origin with at least 85 % mass ethanol, to determine the background.
4.4. Alcohol from recent raw materials of the most recent vegetation period with at least 85 % mass ethanol as reference material.
5. APPARATUS
5.1. Multi-channel liquid scintillation spectrometer with processor and automatic external standardisation and display of the external standard/channel ratio (usual design: three meter channels and two external standard channels).
5.2. Low-potassium counter tubes suitable for the spectrometer, with dark screw-tops containing a polyethylene insert.
5.3. Volumetric pipettes, 10 ml.
5.4. Automatic dosing device 10 ml.
5.5. 250 ml round-bottom flask with ground-glass stopper.
5.6. Alcohol distillation apparatus with heating mantle, e.g. type Micko.
5.7. Microliter syringe 50 μl.
5.8. Pycnometer funnel, pycnometers, 25 ml and 50 ml.
5.9. Thermostat with a temperature stability of ± 0,01 °C.
5.10. Official alcohol tables in accordance with the Council Directive of 27 July 1976 on the approximation of the laws of Member States relating to alcohol tables, published by the Commission of the European Communities (ISBN 92-825-0146-9).
6. PROCEDURE
6.1. Adjusting the equipment
The equipment should be adjusted according to the manufacturer's instructions. Measuring conditions are optimal when the value E2/B, the quality index, is at its maximum.
E= efficiency
B= background
Only two meter channels are optimised. The third is left fully open for control purposes.
6.2. Selection of counter tubes
A larger number of counter tubes than will later be needed are each filled with 10 ml of 14C-free synthesis ethanol and 10 ml toluene scintillator. Each is measured for at least × 100 minutes. Tubes whose backgrounds vary by more than ± 1 % rel. from the mean are discarded. Only tubes new from the factory and from the same batch may be used.
6.3. Determination of the external standard/channel ratio (ESCR)
During the process of setting the channels (6.1) the ESCR is determined using the appropriate computer program when the efficiency is determined. The external standard used is 137caesium, which is already built-in by the manufacturer.
6.4. Preparation of sample
Samples having an ethanol content of at least 85 % mass and free from impurities, which absorb at wavelengths below 450 nm can be measured. The low residue of esters and aldehydes is not a problem. After the first few ml have been discarded the sample is distilled direct into the pycnometer and the alcohol content of the sample is determined by pycnometry. The values to be determined are taken from the Official Alcohol Tables.
7. MEASUREMENT OF SAMPLES USING EXTERNAL STANDARD
7.1. Slightly extinguished samples such as those described in 6.4 with an ESCR of around 1.8 may be measured via the ESCR, which provides a measure of the efficiency.
7.2. Measurement
10 ml each of the samples prepared according to 6.4 is pipettes into a selected counter tube checked for background and 10 ml of toluene scintillator is added via an automatic dosing device. The samples in the tubes are homogenised by suitable rotary movements; the liquid must not be allowed to wet the polyethylene insert in the screw-top. A tube containing 14C-free fossil ethanol is prepared in the same way to measure the background. To check the relevant annual 14C value a duplicate of recent ethanol from the latest vegetation period is prepared, a tube being mixed with internal standard, see 8.
The control and background samples are placed at the beginning of the measurement series, which should contain no more than 10 samples for analysis. Total measuring time per sample is at least 2 × 100 minutes, with the individual samples being measured in part stages of 100 minutes so that any equipment drift or other defect can be detected. (One cycle therefore corresponds to a measuring interval of 100 minutes per sample).
Background and control samples should be freshly prepared every four weeks.
This method requires little time and material and is particularly suitable for non-specialist laboratories processing large numbers of samples.
In the case of slightly extinguished samples (ESCR circa 1,8) the efficiency is only negligibly affected by the change in this value. If the change is within ± 5 % rel. the same efficiency can be expected. For more greatly extinguished samples, such as denatured alcohols, the efficiency can be established via the extinction correction graph. If an appropriate computer program is not available the internal standard must be used, and this gives an unambiguous result.
8. MEASURING SAMPLES USING INTERNAL STANDARD HEXADECANE14C
8.1. Procedure
Control and background samples (recent and fossil ethanol) and the unknown material are each measured as duplicates. One sample of the duplicate is prepared in a non-selected tube and an accurately dosed quantity (30 μl) of hexadecane14C is added as internal standard (added activity around 26269 dpm/gC approximately 43782 cBq/gC). For the sample preparation and measuring time of the other samples see 7.2, but the measuring time for the samples with the internal standard can be reduced to about five minutes by presetting at 105 pulses. One duplicate each of background and control samples is used per measuring series; these are placed at the beginning of the measuring series.
8.2. Handling the internal standard and counter tubes
To prevent contamination when measuring with the internal standard these must be stored and handled well away from the area where the samples for analysis are prepared and measured. After measurement the tubes checked for background may be re-used. The screw-tops and tubes containing the internal standard are disposed of.
9. EXPRESSION OF THE RESULTS
9.1. The unit of activity of a radio-active substance is the becquerel; 1 Bq = 1 decay/sec.
Indication of specific radio-activity is expressed as becquerels relative to one gram carbon = Bq/gC.
To obtain more practical results it is best to express the results in centi-bequerels = cBq/gC.
The descriptions and formulae used in the literature, based on dpm, may be retained for the time being. To obtain corresponding figures in cBq merely multiply the dpm figure by 100/60.
