Product Description

Butyric‚Äú, like baby vomit or spent grains, rancid”

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

The origin of butyric acid in cider-making is unclear but it is most likely associated with use of poor quality apples which have suffered from bacterial rot. It imparts a rancid flavour to cider, with the intensity of the note being affected by product pH value.

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

IMPORTANCE

The odour of butyric acid is reminiscent of that of rancid butter or baby vomit. The flavour of affected ciders can be worsened by the presence of 2,3-butanedione, or improved by ethyl butyrate derived from metabolism of butyric acid by yeast during fermentation.

ORIGINS

The origin of butyric acid in cider-making is unclear. However, it is likely that it is produced in apples of poor quality prior to pressing due to the action of contaminant bacteria, including Bacillus and Clostridium.

HOW TO TASTE

The best way to detect butyric acid in cider 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.

CAS NUMBER

The CAS registry number of acetaldehyde is 107-92-6.
