Wine fault/taint vials

In today’s highly competitive market, the purchase of one ‘bad’ bottle of wine can be enough to influence a consumer to seek an alternative brand or label.

To assist wine producers and other key wine industry stakeholders in their quest for producing and selling high quality, taint- and fault-free wines, AWRI’s Analytical Service is now offering for sale vials containing pre-measured quantities of 12 commonly encountered ‘Wine fault/taint’ chemicals. When mixed into a 750 mL bottle of wine, these chemicals yield ‘spoiled’ wines which can be used for Sensory Assessment training or for comparison purposes.

Kits may be assembled from any number or combination of the following compounds:
