Ethyl Butyrate Beer Flavour Standard

Ethyl Butyrate (ethyl butanoate)

Ethyl Butyrate is perceived as a tropical fruit, tutti fruity, mango or pineapple flavour. One of the ester flavours found in most beers, it can also be perceived as a slightly cheesy fruit flavour. Ethyl Butyrate generally occurs in beers due to fermentation and too much is normally considered an off flavour.

Ethyl Butyrate can also be introduced into beers due to poor brewhouse hygiene as worts can end up containing butyric acid and enhances the production of this flavour.

This flavour although common is more prominent in some beers than others, we recommend that all beer sensory panelists are trained in this flavour. However regular training is dependant on whether this is a common problem in your specific brewery.

Our Ethyl Butyrate is available in blister packs of 5 capsules.

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


Ethyl butyrate is one of a range of butyrate esters found in beer. Such flavours are important in defining the character of several major lager beer brands.
