“Catty, like blackcurrant juice or tom cat urine”
Certified Beer flavour standard used to train professional beer tasters to recognize and scale the intensity of catty character. Catty notes in beer can arise in several ways. They can occur as a positive note via hops; an off-flavour associated with beer ageing; and a taint derived from the interaction of a chemical contaminant with a yeast metabolite.
