Krausen has fallen Like the first krausen... Never mind that. Usually I let my lagers sit in the primary for 3 weeks. I brewed a Munich Helles on June 27th. The yeast said I should see activity within hours. I did not. It took a day. I did start it warm, as the instructions said. I think it was 24 hours when I reduced the temp. It took about 48 hours from pitching to see a krausen start to form. A day later, it was good and thick. I looked at it today, and the krausen has fallen. I'm contemplating raising the temp to 68° or so now for a couple days, and then racking and lowering gradually to lagering temp. My question, do you think if I raised the temp to 68° now for 2 days that the fermentation would be complete, based on the variables I stated? I can't really pull a sample to check with my hydrometer. The carboy is too tall. I did buy a baster to draw a sample, but it leaks so badly I can't fill my thief with it. Maybe I'll put a hose clamp on it and try.
