culturing a week or two in advance.

As far as cooling and maintaining such a large volumn of wort I intend
to ferment in smaller containers. I also have access to 55 gallong
containers that I think will make excellent fermentors, so once the
initial brewing is done I am going to break the fermentation down to
the smaller containers, then into a climate controlled building to
ferment. I do not know how much yeast I will need, I do not know how
much of anything yet, that is why I am looking for help.

have to rush out and do today. The brew pot is not going anywhere so I
have some time to get some home work done. When I make the brew I will
invite you guys up for a glass of beer, I think I will have enough to
go around and it is not far from your home stompoing grounds, maybe
thirty five miles.
