“Acetaldehyde, like emulsion paint or green apples”

Certified spirits flavour standard used to train professional beer tasters to recognize and scale the intensity of acetaldehyde character. Acetaldehyde is produced by yeast during fermentation. It imparts an apple-like flavour to cider, perceived as somewhat like emulsion paint as the concentration is increased. High levels can be indicative of process problems.
