Yeast food is a blend of yeast nutrients formulated to increase yeast activity during fermentation so that attenuation can be reached more rapidly and the fermentation cycle shortened. This shortening of the lag phase can help reduce off-flavours in beer that are due to bacteriological contamination. Yeast food can cause a reduction in the final gravity by invigorating the yeast and enabling it to give a more complete fermentation. This can reduce the diacetyl content in the finished beer.
The blend contains nutrients and minerals.
It should be slurried in a few litres of liquid and added to the kettle towards the end of the boil.
Appearance: Free flowing pale brown to yellow crystalline powder
