Product Description

Leathery, like new leather”

Beer flavour standard used to train professional beer tasters to recognize and scale the intensity of leathery character.

Isobutylquinoline and related compounds are formed in beer during ageing in package It acts synergistically with other flavour notes to impart a stale off-flavour to beer.

Food grade | Free from sensory impurities | Extensively tested | Safe to smell and taste.

IMPORTANCE

ORIGINS

It is likely that compound other than, and in addition to, isobutylquinoline are responsible for the leathery flavour associated with stale beer.

Leathery flavour characters resulting from oxidation are best detected in beer as follows. Without covering the glass, swirl the beer to release the aroma. Take a single short sniff. Repeat as necessary.
