Mark Ekkerman
Head of Laboratory
"We heat up 1 millilitre of the wine sample, making its substances volatile for precise analysis. Cork taint, such as 2,4,6-trichloroanisole (TCA), can be detected at levels below 1 part per trillion. This advanced technology, adapted from the food industry, allows us to confirm even the faintest off-notes in wine."
