Thanks a lot drawdy10, I now understand how it should be done. I'm sorry but I don't know what to answer to your question, I guess it's because I don't have any. I was going to place the fermentor in the coolest room I can find.
About the yeast, I couldn't find the WLP400 or the Wyeast alternative one, so I got Wyeast Forbidden Fruit and Safbrew WB-06. Since I'm a new with this I wanted to see by myself the difference yeast makes to the beer and I was planning on brewing 10 liters in total (5 liters for each yeast).
What do you think? I'd like to know your opinion
