  • Flavour chemistry: identifying faults in wine

    What do “volatile acidity” and “reduction” smell like? What is the difference between a taint and an off-flavour? Find out at this tasting, led by sensory scientist Sietze Wijma.

    Hundreds of different flavour and aroma compounds have been identified in wine. These can be traced back to different grape varieties, winemaking techniques and microorganisms. However, sometimes things don’t go according to plan. The unintentional appearance of wild yeast and bacteria can result in undesirable flavours. Taints can come from various external sources in the vineyard and the winery.

    During this masterclass, you will learn to identify 10 important faults in wine by tasting. We will discuss the origins of the fault and what preventive and corrective measures are available to the winemaker.


    How will it work?

    You will receive 11 glasses of the same neutral wine, where 10 glasses have a single flavour compound added. These are the compounds that have been identified by the scientific community as being responsible for a certain fault. Examples of these compounds are TCA, acetaldehyde and guaiacol.

    The session will conclude with a blind recognition activity to put your tasting skills to the test. This is the perfect event for any intermediate-level wine students or enthusiasts looking to take their tasting ability to the next level!
