Yeast cultures composed of multiple strains require longer fermentation periods than those of lesser number. At temperatures below 60°F, time of fermentation becomes greater, and is more significant as temperature is lowered. When SO2 is added in amounts of 20 ppm or less, the effect on fermentation is slight. At 40 ppm the effect becomes quite measurable, with a 7-day prolongation of fermentation time. Wet compressed yeast offers many advantages over traditional culture. In use, propagation or preparation systems may be simple, or entirely eliminated, with considerable savings in time and control program. A vigorous end fermentation is secured, this being essential for cold fermentations below 60°F. ER -
