Primitive density of must

The primitive density of must corresponds to the dry Pourcentage in Masse of Extrait from the Moût before Fermentation.

Scales of mesure

See also: Degree Baume, Scale of Brix, Degree Balling, Degree Plato

The scale of Balling was developed by the German chemist Karl Balling. It gives the concentration of a solution of Saccharose expressed as a percentage its weight to a temperature of 17,5 °C.

The scale of Brix is initially resulting from a recalculation of the scale of Balling by Antoine Brix with a temperature of reference of 15,5 °C. That currently used comes from new calculations with a temperature of reference of 20,0 °C. A good approximation is given by the formula 261,3 × (1 - 1/G) where G is the density of the solution with 20,0 °C.

The scale of Plato is also an improvement of the scale of Balling. It uses a temperature of reference of 17,5 °C and a slightly different measurement. A good approximation is given by the formula 260,0 × (1 - 1/G) where G is the density of the solution with 17,5 °C.

The three scales are often interchangeable because the differences are tiny:

  • the scale of Brix is especially used for fruit juices, the wine making and the industry of sugar.
  • the scale of Plato is mainly used in the brewery field.
  • the scale of Balling still remains on old saccharimeters and is always used in the industry of the wine in South Africa.

Legislation

The primitive density of must is used in Germany in calculation of the tax on beer. The categories are

  • 0-7  %: Einfachbiere (example: Malzbier )
  • 7-11  %: Schankbiere (example: Berliner Weiße )
  • 11-14  %: Vollbiere (examples: Pils , Weizen )
  • 16-28  %: Starkbiere (example: Doppelbock )

In Swiss, a bill in process of examination at the Parliament (2006) follows the same diagram:

; Article 10 - Base of calculation
  1. the tax is calculated per hectolitre and on the basis of content of must of origin, expressed in Plato degrees.
  2. the Plato degree is the content of must of origin of beer, expressed in grams by 100 grams of beer, such as it is given using the great formula of Balling on the basis of of the alcoholic strength and content of extract.
  3. At the time of the determination of the Plato degree, only the first decimal is taken into account.

; Article 11 - Income tax rate

  1. the tax is assembled to:
  2. : a. up to 10,0 degrees Plato (light beer) 16 FR. 88 per hectolitre;
  3. : B. from 10,1 to 14,0 degrees Plato (normal or special beer) 25 FR. 32 per hectolitre;
  4. : C. starting from 14,1 degrees Plato (strong beer) 33 FR. 76 per hectolitre.
  5. the beer whose alcoholic strength does not exceed 0,5% of volume (beer without alcohol) is exonerated from the tax.
