Beer Sensory

Cause of Flavour

One of the basic tastes - bitterness is important for all beverages. Being able to understand it for products that are typically bitter and being able to detect it in products that should not have bitterness.

Bitterness is important in many beers - as it is imparted by hops during the brewing process. Craft beer and other beer styles are focused on high bitterness levels and unique bitterness profiles.

Coffee Sensory


The fundamental taste factor associated with a caffeine solution.

FlavorActiV's GMP Flavour Reference Standard Bitter 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 Bitter is of the 24 validated flavour reference standards.
