I brewed a milk chocolate stout from northern brewer on 4-13-13, everything seemed to be going as planned and this morning I didn't see any real activity I opened it up and still see a thick head of krausen on top, I guess let me back track I used wyeast smack pack 1332 northwest ale yeast, I also made a 16oz/.5 cup dme starter, I let that finish decanted, added fresh wort and did this three times so I could have a great starter for fermentation.i have been fermenting it at temps between 65--68 degrees as the package says 65--75 for optimum temp...now am I just being a newbie and being to hasty with this or is this something I need to worry about?? Thanks for all the help
