Still Spirits Heat Wave Turbo Yeast

This is the only yeast to use when the air temperature is above 33C. It delivers excellent quality alcohol in hot conditions. Heat Wave is also the only yeast recommended for "stacking" (making more than one batch together in a large fermenter). It is possible to combine up to 8 batches (200 litres) with 8 sachets of Heat Wave yeast as long as the starting liquid temperature & air temperature are both 20C (this is important).
