Just thought I'd bizzump this 4-year-old thread rather than start a new one (it shows that I have done a search, which makes people like me more).
I have a Kolsch which has been in primary just over 2 weeks. I was going to transfer to secondary for lagering next weekend (assuming FG has been reached, I haven't checked yet but was planning on taking a sample on Wednesady), however I only have 25 litre buckets. There's currently about 4 inches of head space at the top of the one I'm currently fermenting in, obviously if I transfer to secondary this will be slightly more as I will be getting rid of the trub.
Basically, will this be ok? If it has reached FG will there still be a little blankie of CO2 protecting mah beer? Or do I need to get a more suitable container to use as a secondary?
Also, while I am here, I will probably be bottling these beers. Will there still be sufficient yeast in suspension to carbonate them after 3 weeks in primary and 4 weeks lagering? If not, any recommendations on how to introduce yeast at bottling time to ensure carbonation? Just add a pinch of US-05 or something?
