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 to 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 which include:
The recommended use level of Yeast Food is 40 ppm (1g/25L). It should be slurried in water and added to the kettle about 15 minutes before the end of boil.
