SUCRE DE RAISIN
COEI-1-SUCRAI Grape sugar (rectified concentrated grape musts)
- Objective, origin and scope of application
Grape sugar is obtained exclusively from grape musts. The addition of grape sugar to wine is subject to regulation.
The label, or, when this is absent, the documentation accompanying the containers of grape sugar, must cite the sugar percentage.
- Properties
Syrupy, milk-white or slightly yellowish liquid with a sugary flavor.

- Tests
3.1. Preparing the Sample
Drawing samples for the various different analyses is difficult; therefore. the following two dilutions are recommended:
3.1.1. Principal Solution I - for the following tests: titration acidity, total sulfur dioxide and total cations
Weigh exactly 200 g of grape sugar. Fill to 500 ml with water.
3.1.2. Principal Solution II - necessary for the following tests: Folin-Ciocalteu index, pH, conductivity, sucrose test and absorbance at 425 nm.
Dilute the grape sugar with water until it has a concentration of 25° ± 0.5° Brix (25 g of sugar in 100 g of solution).
3.2. Refraction Index at 20 °C (total sugars)
3.2.1. Equipment:
The refractometer used gives the following, based on type of graduation:
- 0.1% by mass of sucrose (or dry matter or Brix degrees)
- the 5th decimal of the index of refraction
The refractometer used should be equipped with a thermometer (+ 10 °C at + 30 °C).
3.2.2. Procedure Method:
Place two drops of grape sugar on the surface of the fixed prism. Lower the moving prism and point the instrument toward a light source that illuminates the graduated scale. Observe the line of separation on this scale between a lower clear zone and an upper dark. Read the graduation line at which this line of separation occurs and record the temperature in °C.
3.2.3. Calculation:
If the device is graduated in percentage (m/m) of sucrose (or dry matter or Brix degrees), the measurement converted to 20 °C using Table 2 is recorded in Table 1 which provides (Column 3) total sugar content in percent (m/m) expressed in terms of sugar.
If the device is graduated by refraction index, the index measured at t °C is used to obtain the corresponding value in percent of sucrose (m/m) at t °C in Table 1 (Column 1). This value as expressed at 20 °C using the temperature correction table N° 2, transferred to Table 1, which, in Column 3, gives the total sugar number in percent (m/m) of invert sugar.
To obtain the refraction index at 20 °C, refer to the total sugar content expressed in terms of invert sugar in Table 1.
3.2.4. Recording the Findings:
Total sugar content is expressed parts per 100 by mass of sucrose and is recorded with a decimal.
The refraction index at 20 °C is expressed to 5 decimal places.
3.3. Absorbance of a 25° Brix Solution at 425 nm (Chromatic characteristics)[1]
Proceed to the analysis according to the method described in the Compendium of international methods of wine and must analysis (Method OIV-MA-F1-08).
3.4. Measuring pH[2]
Proceed to the analysis according to the method described in the Compendium of international methods of wine and must analysis (Method OIV-MA-F1-06).
3.5. Titration Acidity[3]
Place 10 ml of Principal Solution I in a cylindrical vessel (3.1.1). Add Proceed to the analysis according to the method described in the Compendium of international methods of wine and must analysis (Method OIV-MA-F1-05).
3.6. Sucrose Test by HPLC[4]
Proceed to the analysis according to the method described in the Compendium of international methods of wine and must analysis (Method OIV-MA-F1-04).
3.7. Sulfur Dioxide[5]
Proceed to the analysis according to the method described in the Compendium of international methods of wine and must analysis (Method OIV-MA-F1-07).
3.8. Folin-Ciocalteu Index of the 25° Brix Solution
Place the following, in order, in a 100 ml volumetric flask:
- 5 ml of Principal Solution II
- 50 ml water
- 5 ml Folin-Ciocalteu reagent (R)
- 20 ml of sodium carbonate solution (R)
Fill to the 100 ml level with water. Stir to homogenize. Wait 30 minutes for the reaction to stabilize.
Determine absorbance at 750 nm in 1 cm as compared with a control prepared with water instead of Principal Solution II.
Expressing the results:
Express the results in the form of an index obtained by multiplying the absorbance by 16 in order to obtain a scale comparable to that used for wines.

Dilute 5 g of grape sugar in 50 ml of water. Dry 50 μl of the dilution and 50 µl of a methyl D-glucopyranoside solution in a concentration of 1 g/liter, (internal standard) under a vacuum in a small 2 ml flask.
Dissolve the residue with 100 μl of pyridine. Add 100 μl of trimethylchlorosilane. Seal the small flask with a teflon stopper and heat at 80 °C for 1 hour. Inject 1 μl with division of the injected volume to 1/60.
