Product Description

‚ÄúIsoamyl acetate, like bananas or boiled sweets”

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

Isoamyl acetate is formed by yeasts during fermentation. The concentration formed is yeast-dependent. Carbonic maceration, must aeration, and must clarity also play a key influence on the amounts formed. The compound contributes a banana-like note and complexity to neutral white wines and to red and white premier wines. When present in excess it can mask key varietal characters.

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

IMPORTANCE

Isoamyl acetate contributes a banana-like odour and aromatic complexity to neutral white wines and both red and white premier wines. It is present in all wines, usually at or above its flavour threshold. When present in excess it may mask some varietal aromas. Must aeration, clarity, fermentation temperature and the use of carbonic maceration are key parameters in its formation.

ORIGINS

Isoamyl acetate is formed by yeasts during fermentation. The concentration formed is yeast-dependent, with aerobic yeasts developing early in the fermentation playing an important role.

HOW TO TASTE

The best way to evaluate banana ester flavour in wine is as follows. Cover the sample with your hand and swirl the glass to release the aroma. Remove your hand and take a single long sniff. Repeat as necessary.
