IMPORTANCE

The odour of butyric acid is reminiscent of rancid butter or baby vomit. The flavour of affected wines can be worsened by the presence of 2,3-butanedione (diacetyl) produced during the malo-lactic fermentation.

ORIGINS

The origin of butyric acid in winemaking is unclear. It is possibly produced in grapes prior to pressing due to the action of contaminant bacteria. Over-vigorous malo-lactic fermentation has also been implicated in formation of butyric acid.

HOW TO TASTE

The best way to detect butyric acid 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.
