I have a Chocolate raspberry stout that has been sitting in the primary since saturday and it was starting to get going pretty good for a little while but the airlock never went crazy like it normally does. I know, airlock activity is never a good indication of fermentation. But, i just popped the top on it and there is no krausen and there is only a VERY small ring of dried krausen just above the beer line. This was my first PM and i have been keeping the fermentation temps at 68 but bumped it up to 70 early this morning. The reason i bumped up the temp is because i have a belgian abbey ale sitting in the primary (been in there almost 2 weeks now) that still hasn't finished out fermenting and i have heard some yeasts get going better at a little higher temps so i figured bumping up the temps on both might get them both going? The belgian seems to be picking up a little bit but the stout isn't at all. Do i maybe need to go warmer or colder to get the fermentation to finish out or what? I was planning on getting the temps up to 72 maybe. Or do i need to do something completely different to get the fermentation to pick up.
Oh yeah, i also used a starter for the first time with this stout and when i started it (the starter) i never saw any airlock activity in the starter nor did i see any activity at all in the wort. Could this maybe also be related to my problem?
