Coffee Sensory

Acetaldehyde (Peapod)

FlavorActiV's GMP Flavour Reference Standard Acetaldehyde has undergone evaluation by the same research team behind the first World Coffee Research Lexicon, and has been approved for inclusion within the latest World Coffee Research Lexicon as a validated coffee flavour reference.

In early 2014, together with two of the coffee industry’s leading organisations, FlavorActiV developed and launched an advanced Calibrating Coffee Sensory Plan to provide cupper training, cupper calibration and coffee tools throughout the coffee supply chain. In 2016 FlavorActiV partnered with World Coffee Research to validate the use of FlavorActiV's GMP Flavour Standards as reference standards within WCR's lexicon. FlavorActiV's Acetaldehyde is of the 24 validated flavour reference standards.
