Product Description

Musty-TBA, like corked wine with a rubbery overtone”

Certified wine flavour standard used to train professional tasters to recognize and scale the intensity of musty character.

Tribromoanisole taints can be contributed to wine by contaminated cork closures. Such is their incredible flavour activity they can also be picked up from the winery environment via airborne transmission. These compounds suppress varietal characters in wine when present at low concentration. When present above their recognition threshold they impart unpleasant musty, mouldy odours, reminiscent of wet hessian.

Food grade | free from sensory impurities | extensively tested | safe to smell and taste.

IMPORTANCE

2,4,6-Tribromoanisole suppresses varietal characters in wine when present at low concentrations. It imparts an unpleasant musty, mouldy odour to wine, imparting a flavour which is reminiscent of wet hessian. It is derived from methylation of bromophenols by moulds. This is one of the few flavours that can taint wine through airborne contamination during production.
