Wine Proficiency Testing Scheme

Laboratories play an important role in the monitoring of wine production at all stages of wine making, including: grape ripening, must adjustment, fermentation, stabilization and maturation. Analytical testing of grapes and wine complements the art of winemaking by assisting with:

  • Quality control in ripening, processing and aging of grapes & wines

  • Spoilage reduction

  • Process improvement

  • Blending precision

  • Export certification

  • Regulatory requirements

Wine quality and in particular chemical and physical analysis is generally dependent on a winery’s own winemaking staff and, in some instances, that of independent testing laboratories. The reliability of these results can be difficult to assess in-house, and participation in an Inter-Laboratory Comparison Programme (ILCP) can alert you to potential problems, and assist you to gauge your performance against other laboratories.

 

Wine Sample Description

Two wine samples (red and white) are despatched three times per year – February, June and October. An optional extra is also available in each round - grape juice (in February), Méthode Traditionnelle (in June) and Rosé (in October). Refer to timetable.

Participants are given up to 2 weeks to examine the samples and return results.
