I was wondering if the Saccaromyces cereviseae sold in the supermarket are active yeast. Anyone tryed it? couldn't read the whole thread.
Also, could bananas replace malted grain for beta and alpha amylase? Or should I just spit in my Mash? (Apocalyptic cenario, I should malt my own cereal ;) )
Not 50/50 if the water is frozen.. In fact it will need to be much less since latent heat (melting) is so much bigger than sensible heat.
To decrease temperature almost instantaneosly from 100ºC (boiling temp) to 24ºC (about 75F) you will need 0,72 liters of frozen water for every liter of most...
