Detailed explanation-1: -In terms of fermentation, lager yeasts are routinely fermented between 40–54 °F (4–12 ºC) while ale yeast is used from 55–70 °F (13–21 ºC). The optimal fermenting temperatures of yeast vary considerably. Some ale yeasts for example, do not perform well below 65 °F (18 ºC).
Detailed explanation-2: -Fermentation temperature during bottom fermentation ranges from 5 to 16°C. An increase in temperature can result in increased yeast activity deterioration of foam stability and beer colour, decrease in pH and higher loss of bitter compounds.
Detailed explanation-3: -SafLager™ W-34/70 allows the brewing of beers with a good balance of floral and fruity aromas and gives clean flavors and high drinkable beers. Yeast Features: Ideal Fermentation Temperature: 52–58F.
