I use a lot of Northern brewer beer and have started using Brewers Best also. On some of those instructions in Brewers Best it says to let yeast ferment 5 to 7 days and transfer BEFORE fermentation is done. What is up with that? I thought that would defeat the purpose of fermentation in the primary? This is in the instructions of American pale ale and American pale wheat which after 12 days i still have active fermentation which i have never had before in 14 previous beer batches since i have got into home brew. Still have not moved to secondary for fear of losing active fermentation. Any ideas?
