Wine Standards

SAWLA is introducing the use of Wine Standards in South Africa, so that our wine industry can regain its former position in the international market, using an indisputable scientific approach. To avoid discrepancies in the results obtained from different laboratories, incontestable wine standards can be used to ensure you produce reliable and accurate results.

Our company is currently supplying wine standards developed in France and used in Europe. Made to Certification ISO 9001: 2000 standards and providing both, a reference to calibrate apparatus and to assess and control methods of measurement.

The calibration reference

• AA supplies a range of ordinate values for the 7 most common parameters to calibrate the response patterns of automatic equipment. (1 box = 20 x 10ml ampoules)

• IR is a calibration range (ascending alcohol, descending sugar) designed to measure the reducing sugars/alcohols pair by infrared reflectance in fermenting wines.

The control reference

• BTA addresses 15 parameters. Used every 10 samples of wine analysed. If a deviation in the value measured is observed over time then corrective action is called for. (1 box = 20 x 10ml ampoules)

• BTB is designed for controlling manual analyses. 15 parameters can be accurately obtained. (1 box = 6 x 250ml bottles)

Total Acidity (TA) and Volatile Acidity (VA) values are based on g dH2SO4/L

BTB values are also derive in meq/L
