  1. Haha i think anything about 8c is good for us Brit's, anything about 20c/25c is just to much, it gets very humid very quickly and so becomes uncomfortable. Its about 13c here as i write this and its perfect for an out door drink. 

  2. hi, i am wondering, do you live in England? if so define hot. i am interested because i know someone who lives in England and i asked how the weather was and he said it was quite warm and i asked what the temp was and he said about 10c where i live the only time it gets below 10 is at 3 am in the morning in the middle of winter!!!! and in summer it can get up to 40

  3. I'm not an chemist, just a lowly engineer. But what is the yeast doing? Is it a catalyst or is it a reactant? You are not explaining clearly what the active yeast is contributing.
