Isoamyl Acetate Beer Flavour Standard

Isoamyl Acetate

Isoamyl Acetate is a common ester flavour which is present in all beers. It is perceived as a banana, pear drop or fruit like flavour.

This flavour plays an important part in all beers and the overall flavour profile of the product. Isoamyl Acetate is produced by yeast during fermentation and is present in large amounts due to this. However this flavour can be a serious flavour impact character if it is present at high levels.

As this is one of the most common flavour components of beer we recommend that all sensory panels are trained and tested with this flavour at regular intervals.

Our Isoamyl Acetate Beer Flavour Standards are available in blister packs contain 5 capsules.

To train with this flavour cover the sample glass with your hand and swirl to release the aroma. Remove your hand and take a single long sniff.


Isoamyl Acetate is a recommended flavour standard of ASBC and the EBC.
