The addition of tirage liqueur may not cause an increase in the total alcoholic strength by volume of the cuvée of more than 1,5 % vol. This increase shall be measured by calculating the difference between the total alcoholic strength by volume of the cuvée and the total alcoholic strength by volume of the sparkling wine before any expedition liqueur is added.6.The addition of expedition liqueur shall be carried out in such a way as not to increase the actual alcoholic strength by volume of the sparkling wine by more than 0,5 % vol.7.Sweetening of the cuvée and its constituents shall be prohibited.8.In addition to any acidification or deacidification of the constituents of the cuvée in accordance with Regulation (EC) No 479/2008, the cuvée may be subject to acidification or deacidification. Acidification and deacidification of the cuvée shall be mutually exclusive. Acidification may be carried out only up to a maximum of 1,5 grams per litre, expressed as tartaric acid, i.e. 20 milliequivalents per litre.9.In years of exceptional climate conditions, the maximum limit of 1,5 grams per litre or 20 milliequivalents per litre may be raised to 2.5 grams per litre or 34 milliequivalents per litre, provided that the natural acidity of the products is not less than 3 g/l, expressed as tartaric acid, or 40 milliequivalents per litre.10.The carbon dioxide contained in the sparkling wines may be produced only as a result of the alcoholic fermentation of the cuvée from which such wine is prepared.Such fermentation, unless it is intended for processing grapes, grape must or partially fermented grape must directly into sparkling wine, may result only from the addition of tirage liqueur.

Cool the two tubes externally with the freezing mixture. Connect the flask to the collecting tubes and begin to flush the apparatus with nitrogen at a rate of three litres per hour. Heat the wine to 80 °C with the heating mantle, distil and collect 45 to 50 ml of the distillate.Stabilize the chromatograph. It is recommended that the following conditions are used:injector temperature: 200 °C,column temperature: 130 °C,helium carrier gas flow rate: 20 ml per minute.With the microsyringe, introduce a volume of the standard solution such that the peak corresponding to the allyl isothiocyanate can easily be identified on the gas chromatogram.Similarly introduce an aliquot of the distillate into the chromatograph. Check that the retention time of the peak obtained corresponds with that of the peak of allyl isothiocyanate.Under the conditions described above, compounds naturally present in the wine will not produce interfering peaks on the chromatogram of the sample solution.Apparatus for distillation under a current of nitrogenB.SPECIAL ANALYSIS METHODS FOR RECTIFIED CONCENTRATED GRAPE MUST(a)Total cations1.PrincipleThe test sample is treated by a strongly acid cation exchanger.

Oxidation of the ethanol in the distillate by potassium dichromate. Titration of the excess dichromate with an iron (II) solution.2.Apparatus2.1.Distillation apparatus used to measure the alcoholic strength3.Reagents3.1.Potassium dichromate solution.Dissolve 33,600 g of potassium dichromate, (K2Cr2O7), in sufficient quantity of water to make one litre of solution at 20 °C.One millilitre of this solution oxidizes 7,8924 mg of alcohol.3.2.Iron (II) ammonium sulphate solution.Dissolve 135 g of iron (II) ammonium sulphate, Fe SO4, (NH4)2SO4, 6 H2O in sufficient quantity of water to make one litre of solution and add 20 ml of concentrated sulphuric acid, (H2SO4), (ρ20 = 1,84 g/ml). This solution more or less corresponds to half its volume of dichromate solution when just prepared. Subsequently, it oxidizes slowly.3.3.Potassium permanganate solution.Dissolve 1,088 g of potassium permanganate, KMnO4, in a sufficient quantity of water to make one litre of solution.3.4.Sulphuric acid, diluted 1:2 (v/v).A little at a time and stirring continuously, add 500 ml of sulphuric acid, (H2SO4) (ρ20 = 1,84 g/ml) to 500 ml of water.3.5.Ferrous orthophenanthroline reagent.Dissolve 0,695 g of ferrous sulphate, FeSO4, 7 H2O, in 100 ml of water, and add 1,485 g of orthophenanthroline monohydrate, C12H8N2, H2O. Heat to help the dissolution. This bright red solution keeps well.4.Procedure4.1.DistillationPlace 100 g of rectified concentrated must and 100 ml of water in the distillation flask. Collect the distillate in a 100 ml volumetric flask and make up to the mark with water.4.2.OxidationTake a 300 ml flask with a ground glass stopper and with a widened neck enabling the neck to be rinsed without loss. In the flask, place 20 ml of the titrant potassium dichromate solution (paragraph 3.1) and 20 ml of the 1:2 (v/v) dilute sulphuric acid (paragraph 3.4) and shake. Add 20 ml of the distillate. Stopper the flask, shake, and wait at least 30 minutes, shaking occasionally. (This is the "measurement" flask.)Carry out the titration of the iron (II) ammonium sulphate solution (paragraph 3.2) with respect to the potassium dichromate solution by placing in an identical flask the same quantities of reagents but replacing the 20 ml of distillate by 20 ml of distilled water. (This is the "control" flask.)4.3.TitrationAdd four drops of the orthophenanthroline reagent (paragraph 3.5) to the contents of the "measurement" flask. Titrate the excess dichromate by adding to it the iron (II) ammonium sulphate solution (paragraph 3.2). Stop adding the ferrous solution when the mixture changes from green-blue to brown.To judge the end-point more precisely, change the colour of the mixture back from brown to green-blue with the potassium permanganate solution (paragraph 3.3). Subtract a tenth of the volume of this solution used from the volume of the iron (II) solution added. Let the difference be n ml.Proceed in the same way with the "control" flask. Let n′ ml be the difference here.5.Expression of the resultsThe ethanol is expressed in grams per kilogram of total sugars and is quoted to one decimal place.5.1.Method of calculationn′ ml of ferrous solution reduces 20 ml of dichromate solution which oxidizes 157,85 mg of pure ethanol.One millilitre of iron (II) solution has the same reducing power as:((157,85)/(n)) mg of ethanoln-n′ ml of iron (II) solution have the same reducing power as:157,85 × ((n′ — n)/(n)) mg of ethanol.Ethanol concentration in g/kg of rectified concentrated must is given by:7,892 × ((n′ — n)/(n))Ethanol concentration in g/kg of total sugars is given by:789,2 × ((n′ — n)/(n′ × P))P = percentage (m/m) concentration of total sugars in the rectified concentrated must.(f)Meso-inositol, scyllo-inositol and sucrose1.PrincipleGas chromatography of silylated derivatives.2.Reagents2.1.Internal standard: xylitol (aqueous solution of about 10 g/l to which a spatula tip of sodium azide is added)2.2.Bis(trimethylsilyl)trifluoroacetamide — BSTFA — (C8H18F3NOSi2)2.3.Trimethylchlorosilane (C3H9ClSi)2.4.Pyridine p.A.

After mixing, 100 μl of solution is taken and placed in a flask (point 3.6) where it is dried under a gentle stream of air. 100 μl of absolute ethyl alcohol may be added if necessary to facilitate evaporation.The residue is carefully dissolved in 100 μl of pyridine (paragraph 2.4) and 100 μl of bis(trimethylsilyl)trifluoroacetamide (paragraph 2.2) and 10 μl of trimethylchlorosilane (paragraph 2.3) are added. The flask is closed with the Teflon stopper and heated at 60 °C for one hour.Draw off 0,5 μl of clear fluid and inject using a heated hollow needle in accordance with the stated splitter ratio.5.Calculation of results5.1.A solution is prepared containing:60 g/l of glucose, 60 g/l of fructose, 1 g/l of meso-inositol and 1 g/l of sucrose.5 g of the solution is weighed and the procedure at paragraph 4 followed. The results for meso-inositol and sucrose with respect to xylitol are calculated from the chromatogram.In the case of scyllo-inositol, which is not commercially available and has a retention time lying between the last peak of the anomeric form of glucose and the peak for meso-inositol (see diagram), the same result as for meso-inositol is taken.6.Expression of the results6.1.Meso-inositol and scyllo-inositol are expressed in milligrams per kilogram of total sugars.Sucrose is expressed in grams per kilogram of must.
