Metabolite Identification
Common NameDiacetyl
DescriptionDiacetyl is a natural by-product of secondary or malolactic fermentation. It is also a product of butanoate metabolism. It is a vicinal diketone (two C=O groups, side-by-side) with the molecular formula C4H6O2. It has a buttery aroma. Beer sometimes undergoes a diacetyl rest, which entails waiting two or three days after fermentation is complete, to allow the yeast to absorb the diacetyl it produced earlier in the fermentation cycle. The makers of some wines, such as chardonnay, deliberately promote the production of diacetyl because of the feel and flavors it imparts.
